   Oh, come on.

   The energy to increase fuel economy 25% comes from somewhere The two places I can see are: 1. increasing the carnot cycle efficiency, but that would require a hotter engine, or 2. better burning unburned fuel, as the article implies. Is this saying that 20% of your gasoline goes unburned in the engine?

   I have read this before on the internet. I bought some acetone at the hardware store and added some to my gas tank. I tried this in a 1990 Geo Tracker and a 1992 Dodge Dakota pickup. I did not notice any change at all in performance or gas mileage.

   That’s what it sounds like, but this topic is out of my league. Any know if we can trust this?

   “That excess fuel was formerly wasted past the rings or sent out the tailpipe but when mixed with acetone it gets burned, though the engine still thinks it is running straight gas.”

   Those “Cheap plastic innerds” he was mentioning generally include the tube that you would have to pour the acetone through to reach your gas tank. oh and the paint on the outside of your car as well.

   Not Recommended.

   I’ll take the bait, I’ll try it. I plan to run it on an old gasoline-powered lawnmower with a 1/2 gallon fuel tank. First fill it with pure gasoline, time how long it takes to “fuel-out” and then try with the acetone mixture. If all goes well, the acetone mixture will last longer. I’ll probally be able to test performance and heat at the same time, but will be qualitative, being I don’t have an accurate way to measure performance other than cutting grass

   We found this on a forum last year when gas prices were above $3.00/gal. I ran this in my F150, and my two co-workers in their 2002 Rav 4 and Subaru Outback. All three of us noticed gains in gas mileage and performance. The biggest difference was in my F150 (5.4L V8 4×4). I went from 16mpg (city/highway) to 18mpg over the course of 4 weeks. Right now i average about 19.5 with my driving to work which is about 25%city and 75% highway. My co-workers also saw gains of 10% - 20% in mpg for their 4cycl.

   If we stop using it, which we all tested mpg went back down. We also found it was true if you use too much acetone, it has an adverse affect. My truck fell to 12mpg with 8:10. I have been running it in my truck for almost 9 months now and i have no leaks from degrading plastic, etc.

   We have tried this over a 2500 mile road trip, Fuel efficiency was increased ~15% with no fine tuning of the amount added. Acetone was added to empty Fuel additive bottles and mixed with gas. Mixture was then added to fuel tank

10. David Johnston says:

    It seems like the biggest things to watch out for using acetone are using too much in your mixture and, of course, its tendency to eat up plastics (and the paint on your car). Other than that, this sounds like a pretty neat idea. I’d be interested in trying it at some point.

    Ludicrous…

    If you follow the “reference” articles (all written by Louis LaPoint) all the way back to their source you’ll find the site (also by LaPoint) chock full of total BS.

    This is the standard “I’ve discovered a miracle but a vast conspiracy is keeping me down” sort of thing (see: UFO, bigfoot, 100mpg carboureter, cancer cure, etc.}

    In fact if you use the Turbonater, Tornado, and acetone your car will actually make gas!!

    I did it, I have a spreadsheet documenting my experiments, I got at least 25% increase with the acetone. My research showed me 2 types of information: people who try it and swear it works, and people who say it won’t work so they won’t try it. I suggest running 2 or 3 tanks without it to get baseline mileage per tank first, record both the miles and the gallons at the pump, then use the acetone, 3 oz per 10 gal. It works!

13. Godbear839 says:

    Ran it in my F-150 over the past four months am noticing roughly 50-70 miles more per tankful. also noticed better idle and no hesitation of my gas pedal when I mash it down. If your still unsure about how well it works try it in your lawn mower. That is where we started using it to make sure it doesn’t hurt anything. Also any container that can handle gasoline should be able to handle the acetone. And don’t mind the people like trak they are too afraid to try something new.

    I have been using acetone (2oz/10 US Gal)in my 97 Ford Escort for about a year and it works well in my car. My latest results: driving from Toronto to Ottawa: 4.5 hours travel time at around 60mph (100kph). My car experienced 40 miles per gallon! A similar trip the year before to Windsor (Detroit), I got 31 miles per gallon without acetone.

    In town, my car revs lower, has improved acceleration and the last emmissions test was cut in half compared to the same test done two years ago.

    As for the comment #1: there is no magic here. Energy is not being created. The article explains why: an improved burn due to smaller droplet size. Gasd that would normally be wasted, isn’t.

    It’s winter right now and usually I get 1 week out of a tank of gas. I’m into (but not completed) my second week.

    Measure it correctly when you tank up! 2 to 3oz per 10 US gallons is good. As we’re metric, I use 20 to 23 ml per 10 litres. I put it in the tank before I fill up so the acetone mixes better.

    Look at http://addacetone.com/ for more information.

16. Jdogg says:

    I use 3oz added to the tank WITH A LONG NECK FUNNEL after I fill my 95LX Escort. I get approx. 310 miles per tank (10gal) with acetone, and 280 miles per tank without. A gallon of acetone costs approx $7 to $10. Im still on my first gallon.

    Yes I think its worth using have done so since last summer with no problems.

    Given the fact that modern engines burn 98% of fuel, not 80%, and the other rather dubious claims that LaPointe makes, I would have serious doubt as to whether this actually does anything.

21. Less Cynical than YOU says:

    Ok, so you’re a cynic, that’s obvious. The thing is, you obviously don’t know or rarely leave the small world of your microcube. The Real World does, indeed, have other interests at play which would in fact be adversely impacted by improved fuel efficiency. My dad worked for 35 years as a General Motors engineer, and one of his primary project focuses was fuel economy systems, including exhaust systems. Even then, years ago, the automakers are aware that several high efficiency motors and other fuel economy devices exist, and now they hold the patents to them. I suspect we’ll begin to see them in the upcoming years as Peak Oil becomes a more relevant factor. Point is, my dad tested a carbuerator in 1973 that achieved in excess of 45 MPG then, which would translate to about 60-70 mpg now with the fuel additives which seek to do exactly what acetone supposedly does. It was deemed ‘not conducive to profit stability’ at that time, and propmtly shelved, along with the manufacturing process and design specifics. My father was not allowed to see the interior components of the device, and it had it’s own specific technicians to adjust and tune it. My dad always felt he and his team were being used as observers so there could be a rubber stamp on the closure of the inquiry. They apparently bought the design from a private inventor for a very tidy sum.

    It IS true that the majority of combustion engines operate on an extremly flexible margin of efficiency, which is highly dependent on many factors. Included among those is the (relative) grade of the gasoline, efficiency of the firing system, proper lubrication and efficient waste removal. Also relevant is the method of fuel injection into the pistons for firing in the first place.
    Chemically, as a hydrocarbon, Gasoline does tend to glob together, which is why most FI ports are designed to spray the gasoline evenly along the (hot) sides of the piston, where contact with the sides furthers the evaporation and vaporization process, thereby allowing a greater fuel-*air* mixing to occur. It stands to reason that if the surface tension of the substance, which admittedly I’ve not chemically tested, were to be reduced, the vaporization tempurature and rate would radically increase, thereby improving burn efficiency. This would produce a greater bang for the buck, at the least, but how that affected fuel economy is another matter dependent on the other factors mentioned, and also taking account that simply having proper inflation of your tires can improve your fuel economy, maybe as much as 1-3 miles per 2 gallons, but it all adds up.
    Yes, there is a significant waste of fuel from piston action, somewhere between 4-18% depending on the vehicle, it’s performance, and the efficiency of the engine. You have perhaps noticed that, in an ideal combustion engine using all the fuel it was burning, the end result SHOULD be Water and Carbon Dioxide. In practice, that is no where near the case, and thus the reason for many exhaust components, including catalytic converters, etc, to rectify some of the ‘excess’ to make it ‘environmentally friendly’ and etc.

    I did try this, using a baseline 1:3 addition in my older Cutlass Supreme, 1979. I used this because it’s a big V8 engine, and was quite the guzzler. I was averaging about 15-16 MPG city, and maybe 20-22 Hwy prior to this, and I did notice after the second tank an increase of approximately, well. Here’s the numbers. I have a 12 gallon after market plastic tank. I installed this myself. I filled it with regular, with as low a content of alcohol as I could find, which happened to be a Citgo product. (Don’t buy premium, you’re just buying additives) To that I added 4 ounces Acetone, bought at K-Mart. I pumped in 4 gallons, added the acetone, then filled up to mix it thoroughly, and that has become my routine. Before I did this, I got on average about 235-250 miles to the tank. That remained only slightly different on the first tank full, although the majority of that week was city driving, so that was noticable improvement in just thhat. The second tank saw more improvement, and I ended up getting almost 290 highway miles to the gallon. (286 before I started sputtering, to be exact). To be absolutely certain I was nearing the bottom of my tank, I was carrying a half gallon of gas in a seperate tank, for just this purpose. I didn’t end up using it, but I have to say I remain pleased. I still average around 285-300 a tankful, when I drive that car.

    I must also post that I did notice an increase in output, really. It was particularly apparent when passing, or otherwise rapidly accelerating, and seems to have peaked out after the third tank full.

    I’m not saying this is a panacea for the gas woes, but I trusted this on my baby, and I’m now using it on my 525, for 3 months and with no ill effects. My auto tech knew about this, and was even more skeptical about what I was going to do. He does this with his truck and cars now, and will probably continue to do so, although he won’t advise others to do so which is reasonable.

    About using a lawn mower to test it, I don’t think a two-cycle engine would really see appreciable benefits to the use, although a motorcycle or other sport vehicle might. I’ll think about that for this coming summer. Don’t know if I want to test my Hog on this yet.

    Take these words as you please, but if you’re not sure, buy a beater, learn how to do something other than complain, tune it up, and run about 5 tanks through it. If you can’t find someplace far enough away you’d drive there 5x you’re pretty sad. Do the first two with regular gasoline, purchased from a vendor available at both ends and along the way, then do the third and onward for the last 3 with the acetone mix. If you want to really test how efficient it is, remember to fill up fully, carry a spare tank of ‘reserve’ gasoline to get you to station to fill again, and keep a log every time you drive, and what type of driving it is.

    I’m pretty happy, which is what prompted me to write this. You can take it or leave it

    Oh, and I no affiliation with Louis LaPoint. I actually hadn’t really checked into him very much, just tried it on a car I had planned on selling anyway. Now, however, it’s more useful to drive, and I’ve rediscovered the joy of riding a big steel car again.

26. Andrew Carroll says:

    I’m not doubting that some people are seeing gains, but as with the other miracle cures (tornado, electric supercharger, etc) the gains are mostly perception. For someone going from 31 mpg to 40 mpg on the same trip, I would have to see what other factors such as temperature, speed, wind, traffic, etc, before I would believe you increased your mileage 10 mpg.

    As for the people who say your RPMs stay down around town, don’t you realize that means that you are driving more slowly, or your car is shifting into a higher gear? Once your torque converter locks up (automatic), or your clutch stops slipping (manual) your engine is going to spin at the same RPM at the same speed unless there is another outside factor. Your gear ratio (tranny / differential) and tire size are the only thing that affect RPMs, not your engine. Here’s an example: Let’s say you are going up a hill at 55 mph, and your engine is spinning at 3200 rpm. Your engine is still going to spin at 3200 rpm on level ground at 55 mph (in the same gear), but your injectors are going to be pumping more gas into the cylinders. So, your mileage will vary, but your RPMs won’t.

    But anyways…like the rebunk posted in #18, this really isn’t applicable. I can see there being slight benefits to running acetone through your fuel system and cleaning out varnish and deposits, but the quantity of acetone isn’t sufficient to make any difference. Plus, the downsides (paint, fuel lines, plastics) don’t outweigh the risk.

    wow, congratulations guys! You discovered what happens when you want your gas mileage to go up…you don’t accellerate as hard, you don’t brake as hard or often. You drive slower or more consistently in the “sweet spot” of the engine in top gear.

    sure the oil companies are out to get us, but if it were this easy, the oil companies would be selling fuel additives that were acetone and food coloring, and charging 15 bucks a bottle for them.

29. Some Guy says:

    This totally works!!!!1!!!1!!!11

    I added acetone to my 1986 Ford Escort, and I got 83 mpg city/178mpg highway. Also, my Escort broke the land speed record (although someone with a 1993 Geo Prizm loaded with acetone and wood alcohol beat my speed right afterwards). Also, my car has developed sentience and a cool red led panel on the front of the hood. We travel around the country fighting crime, now, and my perm has never looked better.

    Seriously, it all happened, thanks to acetone. Don’t let the capitalist oil-barons fool you, the only reason they don’t add acetone to all fuel is they want you to keep using more gasoline than necessary and paying less per gallon than they could charge for such “enhanced” super-fuel.

    About using a lawn mower to test it, I don’t think a two-cycle engine would really see appreciable benefits to the use, although a motorcycle or other sport vehicle might. I’ll think about that for this coming summer. Don’t know if I want to test my Hog on this yet.

    Take these words as you please, but if you’re not sure, buy a beater, learn how to do something other than complain, tune it up, and run about 5 tanks through it. If you can’t find someplace far enough away you’d drive there 5x you’re pretty sad. Do the first two with regular gasoline, purchased from a vendor available at both ends and along the way, then do the third and onward for the last 3 with the acetone mix. If you want to really test how efficient it is, remember to fill up fully, carry a spare tank of ‘reserve’ gasoline to get you to station to fill again, and keep a log every time you drive, and what type of driving it is.

    I’m pretty happy, which is what prompted me to write this. You can take it or leave it

    Oh, and I no affiliation with Louis LaPoint. I actually hadn’t really checked into him very much, just tried it on a car I had planned on selling anyway. Now, however, it’s more useful to drive, and I’ve rediscovered the joy of riding a big steel car again.

    This isn’t the sort of thing you can accurately measure using your car. Conditions aren’t constant, so you can’t isolate one parameter (ie: inclusion of acetone in different amounts) for proper analysis. Other considerations: 1) double-blind testing if possible, 2) randomized testing order, 3) elimination of human (driver) factors, etc.

    Also, the referenced web site pushes the use of OBD-II meters for live mpg calculations. This data is not very accurate, as it is often based on the air flow sensor (air flow is proportional to fuel consumption).

    I’m not saying it’s not possible that acetone can influence the combustion characteristics of gasoline. However, if any proponent wants to be taken seriously, proper testing should be done on an engine connected to a dynamometer and fuel-flow measurement. One could also do more accurate emissions measurement. This along with cylinder temperature measurements could help describe exactly where the changes is fuel efficiency originate, either in changes to the engine’s thermodynamic characteristics, or more (or less) complete burning of the fuel.

    The wording in the article smacks heavily of pseudo-science, talking about the “energies” of molecules affecting how others behave. It makes for an entertaining read, but doesn’t give evidence of any real science behind it.

    Lastly, giving selected first-person testimonials doesn’t sway me to believe this really works. “Real-world” testing is very imprecise, people easily get the results they want, and only those data that support the argument are provided. It’s like an informercial that says a food supplement helped people to lose 100lbs. Usually those are non-typical results and the supplement wasn’t the only factor. Often it may not even be a contributing factor, rather one that would be determined to be insignificant under proper scientific study.

    Alice: Try to be more careful about posting pseudo-science as *real* tech.

    How? All a carb does is mixes fuel and air. You know why they don’t make carbs anymore do you?

    It’s called fuel injection. Specific and precise metering and vaporization of fuel as it enters your combustion chamber or intake. They don’t spray on the ‘hot’ part of the cylinder, the whole cylinder is hot and needs the quench of vaporized fuel to avoid hotspots, pinging, and knock.

    Virtually every car today has injectors, because carbs don’t do the job as easily, cheaply, or effectively. They are technology that simply isn’t needed once technology was able to create injectors that can surpass the abilities of carbs. Same reason that nobody uses distributors anymore, just coil packs.

    So, no. I’m not doubting that they had a carb, engine, and car that got 45 mpg. You can go buy a Geo Metro, baby it, and get that mileage out of it without doing anything special. But, a carb that doubles / triples mileage? No way. A gallon of gasoline only has so much energy in it, and while you can get more of that energy to the road by improving drivetrain efficiency, there is a hard limit to how much energy you can get out of it, basically once you have a stoich mix of 14.7:1 air/fuel ratio, then you need to start pumping more air and more fuel into the cylinder to make more power.

    That’s just simple physics and chemestry.

    I’m an analytical chemist so I take this kind of claim with an open skepticism. The Acetone may reduce droplet size, lower vapor pressure and clean out deposits and sludge. However it may also eat into your fuel lines, gaskets and filter meshes so be careful. Toluene and xylene may also give similar performance increases with less risk of damage. I’d like to hear if anyone has tried those two. If I’m not mistaken, formula 1 is gasoline with 20% toluene.

    I wouldn’t risk this on a new engine but if I had a beater I knew would be heading to the yard in a year or two I’d be willing to try this. Correct tire size, balance and tread go just as far to increasing mileage without the potential to damage your car. If boost and get up and go are important, chipping and port polishing are safer. Don’t handle acetone without gloves and ventilation. The flashpoint for acetone is lower then that of gasoline.

    I have not tried this but I did do some research on it this last summer.

    3 ounces of Acetone/10gal will not hurt your car. There are some engine cleaners on the market that use acetone as an ingredient.

    The Berryman Chemicals company list an MSDS for all their additives. You will notice some of these contain quite a bit of acetone as an ingredient. Some of them have over 30% acetone for a 15oz can so that is almost 5 oz to treat up to 15 galons of fuel according to the label.

38. Jim Duncan says:

    First, the only scientific method to test this type of claim is on a Dynamometer - a machine that is used to test automotive variances under IDENTICAL circumstances… A dynamometer can be programmed to replicate the exact driving pattern multiple times - allowing for the only difference to be the fuel additive. These tests probably have not been done because there is no scientific basis to support this claim. The claims made here are totally arbitrary, even if true - there are so many variables when driving in the real world that the “claims of improved mileage” may actually have occurred due to other environmental variances.

    People are always looking for “the miracle cure”, “something for nothing” or the “easy buck”. As with most word-of-mouth passed along miracles, this one has no foundation based on science, only claims from “first-person testimonials”. Perhaps if the people who provided the alleged “first-person testimonials” wore their helmets lined with tin foil (like they were told to!) they wouldn’t have had these strange thoughts transmitted to their (alleged) minds!

    Have been using acetone on a 2001 chevy suburban.
    to get good numbers I have used a diagnostic port reader called a scan gauge (scangauge.com) (cheapest unit I could find)
    gas used is 89 grade exxon (bought from same station at approximately the same time of day each time)

    5 tank average before acetone with mountain, (I live on a mountain) city, and a little bit of highway driving
    11.2 mpg

    20 tank average with 3 oz acetone per 10 gallons of gas
    13.53 mpg

    numbers break down to 1-2 mpg boost on the mountain and city driving
    2-5 mpg boost on highway driving

    the rules are that if there is ethanol in the gas that this won’t work
    use between 1-4 oz per 10 gallons of gas (every vehicle is different. use a gauge to get precise numbers. average at least 4 tanks on a specific ratio to get more concrete numbers before changing the ratio.
    some vehicles see no change mpg wise
    all newer vehicles use a DuPont product called viton for fuel systems. it is resistant to methanol, ethanol, and a lot of other hard core chemicals so disolving or swelling parts is really not an issue

41. Eldapper says:

    Tried in a ‘04 VW Passat Diesel. There was an improvement in mileage that was equivalent to my use of a diesel injector cleaner (the STP or Napa injector cleaner that I use contains acetone). It seems more likely that if your fuel injectors are clean and the fuel pattern is correct, your fuel efficiency increases. A fill-up of my tank shows a range of 620 miles. Driving directly onto the interstate, my range will increase to 640 miles and begin decreasing 20 miles for about every 23 miles driven until the tank shows half-full and by then the trip computer has a handle on the situation and shows mileage decreasing mile for mile. Not using an injector cleaner under the exactly identical conditions my fill-up will show the same 620 miles but drop quickly to 585 and decrease mile for mile.
    So, I stick with the injector cleaner. The acetone is simply too much of a hassle to work with except for perhaps only the most dedicated do-it-yourselfers. The potential for saving a few pennies vs. putting my car warrantee in danger and having an established motor additive company stand behind their product and the peace of mind that comes with that performance promise is worth it to me.

49. Anders Finn says:

    Ok just a couple things here.

    1) “If I’m not mistaken, formula 1 is gasoline with 20% toluene.” nope, not mistaken. That’s formula 1. They’re working with the same thing here.

    2) This talk from “http://www.fuelsaving.info/acetone.htm” is also a bunch of crap. The author has not spent any time actually researching this topic either. He’s guessing. The 98-99% fuel burn is just that, fuel BURNT. Anyone who knows hydro-carbons knows that burning of hydro-carbons does not mean HC + O2 -> CO2 + H20 . . It means HC + N2 + O2 + H2O + others + -> CO2 + H20 + CO + S02 + NOx + other stuff. So “burning” isn’t exactly a great term to describe how the energy transfer works. To get down to it, our best cars get about 15-25% of the energy stored in hydrocarbons out of them (I’m not even talking about wind, powertrain etc losses here, I’m just saying in the engine). It’s not hard to see how a smaller drop size, thus a more even heat distrabution could boost fuel efficendy. HOWEVER

    3) What doesn’t make sense about this to me is why:
    a) isn’t already added to our fuels, this is something gas companies would love and can’t be patented or copyrighted.
    b) isn’t it sold premade in lil 6oz bottles at every gas station by “super gas” or something like that?

    If it’s such a perfect solution, someone would have picked up and started marketing it. To me I also see problems with your injectors with this. Acetone thining out your fuel mix by breaking the hydrogen bonding of the gas and probably interfering with Van Der Waals forces as well. (I’m sorry, I didn’t go look at it THAT closely) I would assume you’d need finer injectors as well. Back about a year ago I was looking at ethanol and moving my vehicle to E90 (90% ethanol and 10% gas) and eventually to 100% Ethanol like the Brazillians do. I found that the MAIN problems were fuel o-rings as ethanol tends to attack many types of rubber and. . well, I’d need new injectors designed for ethanol. Now, that’s not a big deal here, we’re talking about $200 in parts but we’re also talking about skill and a car/truck you can DO this to. Sure, I think that acetone has possibilites here, but I wouldn’t put it in my 2000+ Car or my 1990+ US built car. I’d go find myself a nice mid-80’s to mid-90’s Honda or VW (like a fox =) or something with that wonderful 1.8L 8v. Those cars are troopers as far as the engine goes and are as simple as can be. I’d pull the full fuel system from the tank fill to the injectors and rebuild it with this fuel mix in mind. Then. . well, heh, you already probably bumped up your fuel efficiency a bit right there maybe 2-5% just by cleaning up those dirty injectors and such so. . don’t forget to take your results with a grain of salt. Personally, I recommend NOT doing this with any EFI car unless you know what you are doing.

    side notes:

    Car talk don’t know crap about this kinda stuff. . Sorry guys, yer great but this is not your area.

    Acetone is a serious corrosive and well, it will clean the piss out of your fuel system. If you put it into an anything but new car (or new fuel system), you’re more than likely to plug your injectors, your fuel distributor (or fuel rail) or/and your fuel filter. If you do do this. after you run a couple tanks through, please go change your fuel filter. Your car will thank you.

For those of you that don’t know what all that is. the bigest thing that matters is the carb. the car does not have fule injection. At the time I started useing this I was puting 250 to 300 miles on my car a week. I had to fill up at 250 every week. also my car had got rather slugesh whenever I wanted to pass a car. after the secone day with the acetone in the tank I pulled out to pass a car and the slugishness was gone. but I didn’t notice and gane in gas mileage. but the second tank there was, 50 miles to be exact. I could get 300 miles a tank. on avarage I was geting 25 miles a galion out of a 20 year old sports car. Also Acetone will clean out any bad stough in the fule system. I’ve sence stoped useing Acetone and my millage has droped back down but my car still runs good. I will be useing Acetone again now that I’ve found somewhere to get it buy the galion. And newer cars probly won’t see the big jump in mallage but older cars and those with bigger V8 motors will.

53. alacrity says:

    Something else people might keep in mind while trying the acetone is the air delivery system to the engine. If the gasoline is more vaporized with acetone, then the air requirements will be higher for best burn. Maybe the people who are failing to get good results need more air? (or maybe even just a clean filter)

    That also brings up the question of exhaust restriction. If the engine cannot get rid of the burned gases, that would also reduce the performance.

57. Justin says:

    One thing that I’ve noticed nobody covering is the FLASH POINT. Lower octane fuels require more “spark” to get the same amount of combustion/compression, thus lower mileage. If it takes less energy and you can create a “hotter” spark (lowering cylinder temperature), then you’re fuel efficiency will increase (that comes back to a clean oil pan. Lubrication is a big factor in combustion engine power.) Think about why all of these street racers use nitrous. They sell nitrous in amounts of HP, from a 3+ HP gain, all the way up to 300+ HP gains, depending on the amount of NOS that is injected into the fuel. NOS doesn’t actually increase your horsepower, instead it lowers the temperature of the fuel being delivered to the cylinder; lower fuel temperatures, along with the same amount of energy to ignite the air/fuel mixture creates a bigger bang (transference of energy). That amounts to MORE POWER, or at lower engine speeds, better fuel economy. I can see how the THEORY behind using it might work, as the flash point of acetone is so much lower than petrol, but the cohesion to gasoline atoms is something that I can’t discuss, because I don’t have a chemists degree. Regardless, proper tire pressure, external forces of nature (wind, rain, temp, humidity), INTERNAL LUBRICATION, transmission and rear end lubrication, and a clean exhaust should be sufficient for most people. I have yet to try this, but I’m willing ot put my car up. It’s a 95 BMW 318ti, with an OBDI computer, over 135,000 miles. It averages 29 MPG with 80% highway and 20% city, with an avg speed (recently, at least) of about 45MPH. I can get 400 miles out of the tank with those numbers, higher avg speed I can get 450 out of a tank, but that’s all highway driving at about 80 mph avg. let me lower the flash point of my engine and see what happens.

    January 30th, 2006 at 5:43 pm

60. Justin says:

    Martinelli, I never claimed that it was safe, or without risk, but the Bosch fuel system is limited in the amount of heat that it can dissapate, especially when that heat is trapped INSIDE a cylinder. If you lower your intake temperature, be it by colder air, NOS, or a chemical with a very low flashpoint, it serves the same purpose, some obviously more destructive than others. Hell, if you put too big a NOS shot on, it’ll blow the tops right off the pistons, and/or scour the cylinder walls, but that never stopped anyone that knew the risks. Besides, my BMW is approaching “beater” status.

    January 30th, 2006 at 5:58 pm

61. Dan says:

    Many modern engines have knock sensors that adjust ignition timing depending on the octane rating or knock resistance of the fuel. Using premium will increase power and range because the engine self-adjusts. Acetone just does the same as premium gasoline. You can put your own additives in, or you can buy them at the pump. Of course it helps to be a fuel chemist to know which additives are compatible with the engine components, and it’s nice to have that warranty.

    RE: #42. Honda Civic’s can NOT handle any kind of high compression. Put high performance spark plugs on your civic-SI, and have fun finding a replacement engine head (like a friend of mine did). The head was warped so badly that it could not be repaired (couldn’t handle the extra compression), and SI heads were not to be found at any salvage yard near or far.

    RE: gas mileage. Obviously car companies CAN produce cars that have GREAT mileage. Once Chevy screwed up and made a 1976 Monza: stick-shift, hatchback, rear-wheel-drive, V6 engine. You could squeal the tires in three gears easily and still get 45 (YES FORTY-FIVE) miles to ONE gallon of gas with that car. It may have been a fluke, but if one car can do it by accident, others can too - by design. Consider the forces at play that keep that kind of feul economy out of the consumers hands. It is not a happy thought.

Even put the $$ spent on that last tire squealing start, seems like if you had the choice between getting somewhere fast or going a little bit slower and over the course of a week you have one free lunch, people would drive much nicer.

    I would not try it in my current BMW!!! It is not worth any kind of risk to me.

    Back in 1995 When I was much younger (dumber) I decided to run very high octane gas and alcohol in my (stock) 1991 Chevy Z28 before going out drag racing. I did not notice any change except that the exhaust smelled like burnt candy.

    A short time later one third of my fuel system (injectors - fuel rail - fuel regulator) was plugged up with a white chalky powder. Several of my injectors were also leaking. The motor only had about 40,000 miles on it. I don’t know if I pissed some one off and they put something in my gas tank or if it was the alcohol. My friends and I tried to fix the fuel system but it became a big ongoing catastrophe. The car burnt down in the middle of the street one night while I was driving it. What a mess…

    I would try these other things instead; your vehicle will run better, last longer, and get the mileage that was intended.

    Clean and oiled K&N air filter
    New fuel filter every 15,000 miles
    37 PSI in each balanced & rotated tire
    Bounce test your shocks & struts replace if needed
    New properly gapped spark plugs after 60,000 miles
    New plug wires after 60,000 miles
    Change the Oil every 3,000 miles
    Fuel injection system cleaner every 60,000 miles
    Rebuild carburetor every 60,000 miles
    Distributor cap and rotor every 60,000 miles
    Repack or replace the wheel bearings every 100,000 miles
    Check the timing on older cars
    Clean the junk out of your trunk
    De-virginize the back seat regularly and you won’t care about the mileage

    If you don’t do most of the stuff in the list you will most likely be spending more on big repairs in the future. The mileage will seem trivial at that point.

    Good luck and have fun!!!

I read about it in an old magazine back in the late 80s. It worked very well in high compression engines that were designed to run on leaded fuels. Octanes were designed to slow the fuels burning a little to decrease detonation by spreading the burning cycle out over a longer period of time during the combustion process. It worked great in my el-Camino. But I don’t think I’d try it in a fuel injected car, because I’m not sure about the effects on the o-rings or gaskets. Modern cars have pretty much replaced rubber in the fuel systems with neoprene, but I’m not sure. As far as fuel economy, any time you improve the combustion process you’ll get improvements in fuel economy, but I’m not sure the difference in the costs of the additives will give you any pocket money.

    I’ve been doing this for over 3 months now, since I found out about it. My 98 Blazer with the 4.0 liter Vortec engine went from 16.9 mpg highway to 22 mpg. In the city I’m getting 19 mpg, which is better than what I used to get on the highway!!! And the performance factor shot way up too, like adding nitrous or something. I buy acetone by the gallon at Wal-Mart for about $12, and it last a long long long time. I have a smaller acetone container that I carry around in the Blazer though. I don’t like the idea of carrying a full gallon of acetone. I’ve worked with that stuff for years and know what it’s capable of….
    I was in the process of trying different amounts to see if lessoning it would make the mileage better, less is more with acetone in the gas. I’m using 3 oz per 10 gal now and was going to go down to 2 oz per 10 gal, but I’ve been pulling a trailer and other things and can’t accurately test it.

    Possible I have the year wrong (it was 20 years ago that my friend had this car), but I sure have the car right. I believe it was a Monza-Spider. And don’t tell my about no V6. Six spark plugs = six cylinders, 3 to a side, V-6. I made no claims that this car was advertized to get 45 MPG, I said it DID get 45 MPG (with a powerful V6). Had I been a bit older, I would have bought it from him for the engine alone. I’ve yet to see one like it for performance + mileage.

    @Anders Finn: In what way exactly is my site ( http://www.fuelsaving.info/acetone.htm ) “a bunch of crap” ? Sure, combustion of fuels in engines is a complex process, but so is pretty much any combustion other than pure hydrogen in pure oxygen. We can still use the word “burn”, though.

    Two facts are absolutely determined by experiments:
    1) The remaining chemical energy in the exhaust of a typical modern engine (the amount you waste due to incomplete combustion) is only 1 or 2% of the chemical energy in the input fuel
    2) If you run an engine on completely vaporised fuel - either pre-vaporised gasoline, or a naturally gaseous fuel such as propane - the improvement in economy is vanishingly small

    From (1) and (2) it is not difficult to conclude that
    a) Acetone almost certainly doesn’t give big mileage gains, and
    b) If it does, it almost certainly doesn’t do it by improving vaporisation

    Critics are welcome to discuss this with me further via the email address on my site

    I have a better solution than using acetone…. why don’t you morons that believe acetone increases your gas mileage put water into your gas tank!?!?!?!?! It is free, non-polluting, won’t eat the paint off your car and it is not explosive! Using the “scientific processes” that you claim show increased mileage after adding acetone to your gas tank, I see no reason that you will not be able to make the same claims of increased mileage after adding water…

    Using your same reasoning, I have another “miracle solution” for all of you morons stupid enough to put acetone in your gas tank - hook up your jumper cables to your car battery, hook the other positive cable end to your left ear. Place the negative cable end on your tongue - it will either raise your I.Q. 20 points, or eliminate the problem! Either way, the world benefits!

I have used Acetone for over 5 yeaqrs in my lawn equipment, starts first pull every time! But I also only use Premium gasoline!

    I’m a little skeptical about the great claims of acetone as most of the volatile hydrocarbon based liquids will produce some sort of ‘favorable’ results if viewed through rose-colored lenses.

    Please refer to comments 67, 81, 84

    Over the years I have used a variety of chemicals in my vehicles. Some of my experiences: i had a ‘80 Corolla from ‘83 to ‘94 and i did have a large container of toluene at my disposal to which I would add about one soup can load (approx. 10 ounces) to the gas tank and the engine would run smoother but be prepared to change out the fuel filter more often, at least at the beginning as it will dissolve and move much of the accumulated ‘crap’ that resides in the fuel system especially on an older car. Kinda like a ‘cleansing’ that some people partake in.

    I also picked up an ‘88 Ford Tempo a few years ago for $600 which some may claim was too much but anyways here is the story. The guy was selling it because his wife didn’t trust it any more as it was getting older and it had a tendency to stall at say the lights with your foot on the brake and in ‘drive’. I learned to slip it into neutral and rev it a bit ’til my turn to go. I tried a few bottles of the standard injector cleaner that you add with each fill-up to no avail. That stuff is just paint brush cleaner anyways. When I went to the automotive shop I noticed that they also had ‘heavy duty’ injector cleaner which sold for $14 (can.) for a 350ml aluminum container. On the back for poison treatment it said ‘Warning: contains Naptha’. Another name for naptha is ‘white gas’ or ‘Coleman Fuel’ which all the older lantern and campstoves use. I used the old standard soupcan load for the next two tankloads and problem resolved. Cost - about $7 for 4 litres. A friend was having similar problems with his injection system and it cured it the same way. I now periodically use it on my past ‘89 and present ‘94 Taurus - both V6 3.0L - which get nearly 40 mpg [ 7L / 100km ] on longer highway drives if you don’t drive like an dumb@ss.

    TBONE - see that key on the left side of your keyboard marked “Caps Lock”? Do you know what that key is for? If you press that key, you get Capital Letters EVERYTIME you press a key! Amazing, huh? Obviously, your third grade education has gotten you far!!! Someday (after you save enough money using acetone in your “pull start” lawn equipment), you might be able to afford lawn equipment with an “electric start”! WOW! Until then, I shall do everthing possible to piss off you “rocket scientists” who are conducting research (under the most inconsistant and random circumstances, I might add!) - I am NOT going to use acetone (or any other additive for that matter!). I am going to use only gasoline!!!!!

    If all you “rocket scientists” are so sure this works, why hasn’t anybody PROVEN this with a Dynamometer test? It is very easy to run the same tests with the same car, once with acetone and once without acetone. You haven’t because this test will DISPROVE this myth and you idiots won’t have anything to “brag” about!!

    Not one of the proponents of this myth has provided ANY scientific (or documentable) proof that it improves gas mileage, only “first person testimonials” that are “conducted” under the most uncontrolled, inconsistant fashion possible. They “prove” nothing!! Only that they got “different results” than the last time they checked their gas mileage. There is absolutely NO PROOF offered, only first-person testimonials…. If they expect people to believe it increases gas mileage based on their testimony, why I have several bridges for sale too!! TBONE, are you interested?

    I agree with #38 above - Perhaps if the people who provided the alleged “first-person testimonials” wore their helmets lined with tin foil (like they were told to!) they wouldn’t have had these strange thoughts transmitted to their (alleged) minds!

    I couldn’t have said it better!!!

    all the stuff about molecular bonding may be true but its just a fuel injector/carb cleaner in this instance. treat it as such.

    if you really want a boost, take out your injectors and soak them in acetone for a few days that’ll really clean em up

Before adding acetone, my van was getting 15.7 miles to the gallon. Average in a trip from New Orleans to Houston. I then tried a mixture of 1 oz of acetone per 10 gallons. Monitored this for 3 trips. Milage went to a flat 16mpg. I then tried 2 oz. An increase to 17.3mpg. Then I tried 3 oz, there was a decrease to 14mpg. First I checked plugs, wires, etc.. All were running optimal. I went back to 2 oz mixture. Milage went to 17.5 and has been almost perfectly consistant for the last 12 trips. I think I found my perfect mixture. As far as performance, I noticed no change.
     Next I will try my mixture on my next oil change along with a slightly thinner oil and a quart of Lucas oil stablizer.

102. Beaugrand says:

     The methodlolgy of testing mileage is inherently flawed if you’re running the tank dry. I check my mileage continually, with every fillup, getting a good, clear picture of my average mileage.
     To begin testing you need to start with a FULL fuel tank, and record the odometer reading with the tank FULL. Drive the vehicle normally, until the next time you fill up. Record the odometer again after filling the tank FULL, subtract the old reading from the new to get the actual miles driven, divide this by the amount needed to fill the tank FULL, and you have your mileage. The actual, exact accuracy of the odometer isn’t important (unless the inaccuracy is caused by impending meter failure; in that case, replace it and begin the test all over), because you’re looking for a PERCENT CHANGE in mileage, thus it’s more important to consistently use the SAME odometer and the SAME driving techniques. I do this all the time anyway, because I’m a tightwad.
     You need to do this for several tanks of fuel to establish a “baseline” of fuel economy, then try ONE improvement at a time- increased tire pressure, chassis lube, new shocks (yes, they can affect mileage), fuel additives, whatever.
     I’ve been doing this since I had my first car, in 1968. The best improvement I’ve ever gotten from additives alone was a measly 5% increase in the 1976 Lincoln Town Car I had back in the ’80s (the best overall mileage increase in the Lincoln came from replacing the air and fuel filters, the second came from a combination of installing new tires and new shocks). Some additives, such as gas line antifreeze, actually worsened mileage (not by much, but statistically signifigant).
     Acetone hasn’t worked for me. If it did, I’d use it and keep my mouth shut about it, because I’m a tightwad, and because I’d use that information to invest in companies that produce acetone fuel additive.
     I’m waiting for somebody to rediscover water injection, it actualy works, somewhat.

I do this to protect the valve guides and keep the pistons clean. I have a old 1983 Ford Ranger 4 cylinder and wanting to improve the gas milage. I recently repaired defects in the emission system including hoses but the gas milage is still not good. I think I’ll try the Acetone or Toluene using 2 oz per 10 gals and see if it works. One more thing, don’t use the additive called Restore. It caused me lots of problems when I added it to one of my engines.

105. Victor Carvis says:

     I am laughing my butt off reading some of the comments here. It’s now quite evident to me that the ‘establishment’ (ie. media controlled by Big oil and ‘Big Brother’) has most of you guys totally brainwashed. I want to give you some FACTS based on personal knowledge.

     I work in Harris County Texas (Houston). Here EPA emissions testing is strict w/ special tests done to pass inspection annually. I have used a .28 oz/gal acetone to gasoline ratio in 3 vehicles for over a year now, and emmissions readings on these vehicles have dropped 50% on average. All vehicles have shown an average increase in MPG around 10%. All have shown noticeable increase in power. The smaller 4-cyls (Toyotas) show the most improvement, but the greatest improvement was on my 140K mile ‘96 Plymouth Voyager V6. I had a ‘Service Engine’ light coming on indicating ‘Cylinder Misfire’… and it stayed on for 6 months w/o me figuring out the problem. I started using the acetone additive and it went off after 2 tanks!

     I work for a major petroleum and chemcical engineering company with over 5,000 employees in Houston alone… 40,000 worldwide. After sharing my info in the Houston office, about a dozen ‘brave’ souls tried it. The results I got back I will note below following my 3 vehicles first. I drive a consistent pattern of hiway and intown traffic equaling 700 miles per week. I buy gas at the same station/same pump/same time weekly for normalization of test data, now 1 year out:

     ‘85 Toyota Camry 4-cyl = 10%+ MPG, better performance
     ‘97 Toyota Camry 4-cyl = 9%+ MPG, MUCH better performance
     ‘96 Plym GR Voyager V6 = 12%+ MPG, Corrected ‘Engine Light’

     ‘94 Chev P/U V8 = 12% MPG, more power, better emissions test
     ‘92 Ford Explorer V6 = 5% MPG, passed after failing emissions
     ‘90 Nissan 280Z V6 = 10% MPG, gets 28MPG hiway @ 75MPH

     ‘97 Jeep Cherokee = Passed emissions test after flunking
     ‘01 Toyota Pathfinder = (Ditto above)… 2 tanks after
     ‘94 Lincoln Cont’l V8 = (Ditto above); 10%+ MPG

     All have been saying roughly 10%+ mpg, but most notably the increased performance. If you aren’t getting the mpg, you should be checking the air filters: requires more air to gain new burn efficiency.

     As for asking oil companies… they aren’t going to tell you this is good for many reasons.
     First, they CANNOT add the additive like others because it is so high end distillate that it won’t remain in storage for very long (it dissipates quickly)… and if they can’t control adding it they don’t want you to gain on their profit loss.
     Second, if everyone did this and gained 10% mpg, the immediate loss of 10% market share w/o ANY profit going to Big Oil is a marketing “No-No” to them.
     Third, the corporate farmers pushing ethanol have too much in the pockets of congress to let you know that something this simple works. They want you to burn ethanol (from corn) that maintains the fuel ‘inefficiency’ and keeps not only Big Oil company profits high, but adds another group to the mix in the corporate farmers of ethanol.

     Lastly, if anything were going to damage an internal engine component, ethanol would at a ratio of 1:10 in your gasoline. Most cars built after ‘94 have compensated w/ updated neoprene, N-Buna, and nylon components to handle the ethanol mixtures. Acetone at the ratio mixes we are talking about is 1:200… so miniscule that it is basically immeasurable as to harmful effects on an engine.

     The overall economic impact now w/ gasoline at $3.00/gal of even a 5% increase in mpg = net savings of $0.25/gal if you are purchasing acetone at $12/gal using it at a .25oz/gal ratio. Relationly, the effect is 5 cents per gallon for every percent increase you gain… and if you gained -0- mpg, you would still get a cleaner engine, prolonged engine oil life (less blow-by gas from cylinder rings into oil), and save the life of your catalytic converter… as well as CLEAN UP THE ENVIRONMENT! (Hey, if you are burning more of the same fuel, less of it is escaping into the air… “DUH!”)

     So, you skeptics keep dumping your garbage out there. Anyone with common sense and a will to be environmentally cleaner will at least test the theory. You can see a noticeable difference in performance at the very least, and know that you are emitting much less hydrocarbons into the air.

     What I have noticed is that Wal-Mart is now having to inventory more acetone on their shelves… just ask the mgr of the paint department. More ‘Joe Public’ is learning the truth than you skeptics!

     Tried it, 2000 Dodge Caravan, 3.0 engine….Put 4 oz. in while filling her up, and then hit the highway…247 kms each way to be exact…I put the cruise on at 105 kph, and drove off…Filled up when I returned and put no more acetone in, drove that tank out and then filled up again, no acetone, then set off for the same 247 km each way trip, same cruise, bla, bla, bla…The van normally get around 28 mpg on the highway, on the acetone tank, I got just over 32 mpg.. This vehicle has 100,000 kms on it and was only ever estimated to get 33 mpg when it was brand new….Ya I know, must be a fluke right, wrong, I’ve run the test several times now during different seasons and the same results. The best is when I set her up with the acetone in the tank and set her through the DriveClean emissions test. I zeroed out on almost everything, so low in fact that they ran it again later in the day after checking their own machine, and the second run was the same as the first…
     If you honestly set up a test and there isn’t something seriously wrong with your vehicle you should get excellent results as well…..

     Re: #105-I started using acetone [~2oz/10 gals] in my ‘93 Ford Ranger 3.0 X-Cab 4×4 about 1200 miles ago and stop n’ go mileage has increased from hi 15’s to l7.9.

     Warmer weather and my heightened awareness of the fact I’m trying to improve mileage may account for some of that, but it cannot account for the fact that it most definitely starts quicker and runs more smoothly, with idle RPM’s dropping from 800 down to 725-750 range.

     I’m itching to take it on an extended highway cruise to see if I can beat the 24.6 I posted on a trip to Calif. from Montana August before last…

     I’ve noticed the same thing at WalMart, Victor-they ALWAYS had 4 gallons in stock, and now they’re empty for the past 3 weeks…

     I am going to try this because I have a foster sister that actually works for a big oil company in Houston Tx., and she told me that her boss was not able to let the public know about this because of the lost profits that they would incur if the general public was to become aware of this on a widespread basis. She also told me that a lot of the additives in the higher grades of fuel were made partly of acetone, just not at the ratio of 2-3 oz per every ten gallons,also the additives were not pure acetone and that it was just one of several ingredients, and the pure stuff would surely increase power along with mileage. {She is one of the vice presidents secreaty of Bp oil in TX. So I am going to try it and see what happens.

     well all this is good and makes for interesting read. it may even help in some or many cases.
     my experience is:

     if one wants better performance, mileage and so on a simple change of the cam shaft in the engine (no matter what general consumer gas engine you are running) and you’ll be shocked.

     all of the car mfg have been using the same lift and durations for their big block motors. same cam, same old same old. they won’t change it even just a little because it’ll cost them a couple of bucks and they are indeed working with the oil industry in some manner or another. they are queer for each other i believe.

     ask an automotive engineer, someone with the software to simply check it out. you’ll be surprised what you will find can happen by a simple cam shaft change out. you can get as much as 5 miles or more per gallon of gas.

     with this improvement, we could cut gas consumption by 20% or more if all the new cars were refitted with a different cam and we did the same to the used cars. but, we won’t. we’re pretty wasteful and would rather blame others for our needs.

I tried it Knowing that if it will harm my engine probably just slow it donw. I don’t think it will harm any major components. . i used my car driving at an average of 50km/h . including traffic. before i normally get 5.5 km/L. this morning I refilling my gas I computed the amount of fuel used per km. hmmmmmmmmmm 7.3 km/L? This is something I gotta tell my friends…… Before I use to drive my car to work earlier where there is less traffic but yesterday the whole day I use it . there was traffic anywhere. Shocking isn’t it

     Well, many car manufacturers struggle to meet the required MPG factors required by federal law, meaning, the average fuel economy of all vehicles manufactured by each company must meet a certain floor. In over 20 years, manufuacturer gas mileage has increased only 1 MPG, on average. I am surprised that none of them has used this trick to attempt to get an advantage.

     I still have an 1986 GMC Jimmy 2.8L … 270,000 miles on a virgin engine. I started to have issues with fouling plugs about every 6 months. I was soon to trash the Jimmy. I started with a 2 OZ regiment for every 10 gallons of fuel. I figured it was a junk truck what could it hurt. After the last 2 years I have not needed a set a plugs and my milage went from 17 mpg up to 22 mpg. Now my OD has turned over 285,000 miles.

     Now when I read the fooools like BOB/Mooseman, I am sure they live in a apartment/cell in some big city(jail) and never leave their computer. I on the other hand am a certified mechanic and have personaly seen how clean the components (spark plugs/injecter tips) are and have yet to seen 1 system failure of fuel line degradation are injecter component or O-ring failure. (NOTE: I do not know about the composit floats in old carberators but the brass ones come out clean and the fuel filters last longer from the lack of varnish build-up)

     You tell’em DR.Engine. And by the way: The water powered hydrogen car works and is so simple to convert any car. The implications of putting the oil companys and power companys bankrupt overnight with this new proven technology will be the end of slavery for the american people. These companys and there outright GREED and refusal to lose there nest egg have brought inventers and 6000+ patents to the internet which brings out the truth of Fact vs. Fiction. The internet has made it possable for the world to communicate and that they can not stop. Its sad to see that good men have been Murdered over this new proven technology namely Stan Meyers 1998. The best we can do at this point in politics is to induvidually convert our own cars ourselves. Over all the oil companys will stay alive because the majority of the general public would rather watch Barney than assert any intelligence other than there GED. Sooner than later the oil,power,automotive manufactures reign will come to the end they have brought upon themselves. Then watch how fast these same companys will be cutting each others throats and begging for your business on what is left over after (WE THE PEOPLE) unite. That was the great thing about the 60’s. I have no respect for people that are willingly comatose. These people have less worth than a bag of bird seed. Ironically they are the people in power that supress and do as they are told. You know them well. They are the ones with a box of Dunkin dounuts on there desk. Slavery is alive and well! Convert your own car to run on Hydrogen/Oxygen before you criticize this issue any further. Then you will have the facts needed to live your life on your terms. Imagine all the people with there oil and power Stocks (shares) being totally worthless ovenight. It is comming and they know it. They are doing what most business’s would do if they had the knowledge of bankruptcy on the very near horizon. Rape everyone for every penny that they can get there hands on. Im fortunate enough to have a water powerd car myself and it feels real good to have that extra $200.00+ a month. I am an automotive machinist. I could have been a daycare babysitter and still have done the conversion myself. The only rocket science involved is getting off your azz and do it. If you want to get information on how to do this yourself i can email you all the info you will need. It is readily available right here on the internet as well. If you do not take the time to investigate this claim and make an effort to change your thinking then thats on you. Remember all you need to do is pickup the phone and make the call.

     It works. Nobody should say it does not until they try it. Remember the bumble bee. Therortically it cannot fly…but it does. For crying out loud just try it 1 time with pure acetone at a 1 to 10 mix. 1 time is not going to ruin an engine in those small quantities. I have a geo metro 1.0 liter 5 speed. It should get 50 mpg but the best I can do is 42. After the first tank I gained 2 mpg. I thought this must be fluke. But in secret I also added some to my wifes 2004 Elantra. She has no idea she is using it so in no way is she changing her driving habits. She has told me she always gets between 27 and 28 mpg. I just filled it for her and she got 32 mpg. She is on her second tank now with 2oz with an 11 gallon fill up. At the end of the week I’ll have the second results. She still has no idea what I’m doing. I call this a real test. Forget the facts and figures and theory. If it works it works. I don’t believe in magnetic braclets either but people swear by them. I have no pain so I haven’t tried that yet but my sister and a guy at say they work…no I don’t get it but if it works do it for crying out load.

     It stands to reason that claims that acetone in small quantities can harm a fuel system can only be bunk. Has anyone seen what gasoline can do to oil based compounds (like asphalt for instance). Yes acetone is a strong solvent, but so is gasoline.

     I’ve used it sparing in my first partial tank of gas (only a half ounce in a 14 gallon tank that was less than half full) and I noticed right away a quieter engine (less knock and ping).

     In my second tank, I’ve used three ounces of acetone in the entire tank and I have noticed the gas gage is dropping a lot slower. And when the engine is cold and just started, I can barely hear the lifters in my 1992 Honda Accord, unlike before I used acetone (a 16-valve high mileage engine can be noisy when it’s cold).

     The car has 300,000 miles on it, and runs very, very well. The way I look at it is if I’m ruining my fuel system by using acetone, I’m not a out a lot of cash anyway.

     And with the improvement in fuel economy I expect, I’ll be saving money. If I don’t see an improvement by the time I’ve tried it for one more tank full, I will stop using it. But I’m already greatly encouraged.

     In another few days, I will know conclusively if my fuel economy is improved. I will keep you posted.

127. Ed Sinclair says:

     I saw a device demonstrated at a car show back in 1950 that astounded me. It was a little four bladed impeller that went between the carburator and the intake manifold. It could be slid in and out of place by a lever. When it was out, a straight through hole was in its’ place. The engine was a Ford V8 60 with a single
     throat carb. When the impeller was in place the engine would run on as few as four cylinders.
     When the impeller was removed, the engine would promptly die. The impeller was spun by the intake air rushing past. The claim was that the air/gas mixture was more finely atomized by the impeller thus resulting in a more complete burning of the gas. It made sense to me then and it makes sense now. I have never seen one on the market in all these years. This new “Tornado” works on a similar principle but is not quite the same thing. It seems to me that the spinning impeller really is a better idea. I wish it were still available. I would install it on all my carburated vehicles.

     I did a test run this morning with a 2007 Ranger XLT with a 2.3L 4cyl and a ScanGauge II. It’s a new truck with 1600 miles on it. It had typically achieved 20-22 mpg up to this point. The test run was a 37 mile loop from one exit on I5 to another several miles away, and then back again. It’s a generally straight and flat piece of road in good condition. Weather was clear and mild with no wind. On the first test run it got the expected 22.3 mpg. I then added 2 oz of acetone purchased from NAPA to 12.5 gal of gas. On the second run it got 24.5 mpg - a ten percent increase.

     I’m willing to give this concept a try, and report back as I see more mature results.

     I have been putting acetone in my 89 300ZX and my 97 Corolla for a year now and it has GREATLY IMPROVED my gas mileage. My Z car gets an extra 5 MPG with acetone and my Corolla gets an extra 9 MPG. It took 4 fillups with 2oz per 10 gals to show the peak increase in mileage. My Z car is only driven on weekends and rarely on the highway. My Corolla is driven daily and for road trips. Before, my Corolla was getting 30 mpg on the highway, now 39 mpg with acetone and it is he Base model corolla with the smaller engine and the 3 speed auto. tranny. I have not had any problems whatsoever with either car. DO NOT expect an increase right away, as I said it took 4 fillups to see the BIG increase. Now my 97 corolla is known for having vibration while at idle. It now idles very smooth and I no longer sit in my car while idling to get a massage from all the vibrations.

     As for the acetone dissolving or causing corrosion on plastic parts and fuel lines. Here’s an experiment for you IGNORANT people who are so skeptical about acetone. Go to the auto parts store and buy some fuel line and plastic carburator and fuel injector parts, then put 2-3 ounces of acetone in a big metal tub or drum, then DILUTE IT with 10 gallons of gas and throw in those parts, you will be amazed at all 2-3 ounces of acetone scramble as fast as it can to those parts to start dissolving them. NOT!!!!!! You people are IDIOTS if you believe it. Funny I have never seen Paint Thinner disolve the bristles on cheap Paint Brushes, since Paint Thinner is MOSTLY ACETONE!

     Anything that helps gas vaporize more efficiently in the combustion chamber, IS going to increase mileage. There have been people who have invented vaporizers for cars, and tested a car with a V8 engine would and get 40-60 MPG with the device installed, but as soon as BIG OIL gets word of it, these people Disappear off the face of the Earth. Why? That would cause BIG OIL to lose too much money. You people do realize that European cars (in Europe, not here in the US) in European countries get 10-20% better mileage than American cars do, because BIG OIL Controls more in the US. They could care less about dimenishing fossil fuels or the Enviroment. All they want is MONEY AND POWER.

     lol. this is funny.

     but any who, i have been running acetone for 5 months now. after following various internet sites and friends for the past few years who run it.

     i have always kept fuel/maintenance logs since day one in my 2001 VW 1.8t using a 93 octane ECU program(www.goapr.com).

     i always range from 22–30 mpg depending on time of season and driving habits. twice getting 34mpg on 400+ mile road trips the average mpg was 24.5 (Oct 2003-Jan2007 average)

     over the past 5 months running 2 oz/10 gal acetone i have ranged from 26-32 mpg, averaging 30 mpg(jan 2007-April 2007). i have not been on any trips longer than 100 miles in on drag.

     i use a vag-com diagnostic tool/software (http://www.ross-tech.com/) to occasionally monitor engine parameters. EGTs (exhaust gas temps), injector firing times, and many other parameters have not changed at all using acetone. the only numbers that have changed are the amount of timing being pulled at WOT, and the engine knock count.

     if my fuel system gets eaten up, oh well, i must have f’d up. but for now i’m happy getting ~18% better gas mileage.

No problems with anything on my truck from using it. I have however use it with every other tank and that worked best for me since I would not run my tank down between refills.

138. Pea Brains will believe anything! says:

     Yo acetone guzzling idiots! Now that the acetone has cleaned the fuel injectors (and other most likely gummed-up parts of your fuel system of your cars with 2,458,920 miles on them), have you tried NOT using the acetone anymore? If it is truly the acetone “improving” your MPG, it should decrease back to prior to using acetone levels. I’m quite sure that you will find it does not go back to the prior levels, your fuel system is now clean and running more efficiently.

     Also, after *all* of these so called miracle increases, how come we have not seen one scientifically proven result (dynamometer, etc.)? This is a really a very simple thing to test and actually verify, but I assume that you people who were dropped on your head as babies have no interest in finding out whether acetone is the reason for the increase because it is just another delusion of grandeur in your life that you will have to replace!

     Like Jim Duncan stated up above:
     Perhaps if the people who provided the alleged “first-person testimonials” wore their helmets lined with tin foil (like they were told to!) they wouldn’t have had these strange thoughts transmitted to their (alleged) minds by aliens!

     Hi!

     I read some of this , and i must agree alittel whit the guy calling you mindless sheep.
     The acetone might cleane the fule lines and injectors. So the gaine in hp and milage is the original hp and milage that the car used to have.

     Iv been looking all over the web for any info on how to make my car go longer (faster) and cheaper.

     Im goint to test this thing when iv done building my car and my new engine. I also going to use alcahole injection and water injection. Im also reading on using hydrogen in the car using some of the electrisity that the car produce whit some solar energy.
     I was also thinking of using some electric car brakes to make electrisity when braking.
     More power to make hydrogen-

     If i find any other fule saving tips i might try to use them to.

     My project might cost more then the gaine, but how else can you learn.

     Been reading over these many threads over the past several months.
     Last Wednesday, I decided to try this, by first putting 3.0 oz into my 1998 Subaru Outback wagon with 12 gallons of regular.
     I drove 106 highway miles, mostly level highway miles.
     My wagon has never gotten more than 25 mpg on the freeway. On this first trip of 106 miles, I gassed up at the end of this short trip with 2.9 gallons………..pretty good increase.
     Today, I tried 2.0 oz in my 2003 BMW X5, tank had approximately 13 gallons of fuel already in the tank…..SUV is equipped with the 3.0 automatic. I had business at the same address, 106 miles away, and on the 52 mile trip down, my trip computer read 30.8 mpg. Over the course of owning my bimmer new from the factory in late 2002, I have never gotten this high of reading from the trip computer….and yes, it was reset once I was on cruise on the freeway at 65 mph.
     On the return trip of 52, I was reading 28.9 at 68 mph.
     The best I have ever gotten at 70 mph has been 24.5…..
     I don’t claim to be a chemist or scientist, all I know is what I know.

     I saw this site and thought I’d speak to an industrial chemist. Did that and he said there would be a definite increase for diesel as acetone reduces the surface tension of the fuel. He said there *may* be an increase with petrol, but not likely. He said acetone WOULD NOT compromise any parts if it was diluted 2oz/gallon (25ml per 10 litres).

     I have a 99 Landrover Discovery, V8 Petrol.

     Tried it and saw a 12% increase in enconomy and smoother idle. Next tank I filled up without and saw reduced economy. Been running now for around 12 months. BTW, also ran wiithout acetone a few months back when I went country and didn’t have time to get some acetone - it resulted in WORSE economy…so those who say it only cleans the injectors calling people “pea brains” are obviosly pea brains themselves

     Well, people.
     I get 12 mpg more on a manual transmission GMC sonoma 96′ with X1R and Bosch +4 platinum plugs and a minimum of 7 mpg more on an automatic. These practices have served me well and continue to save me more everyday! On another note, the acetone is only good for keeping the injectors clean and removal of any water deposits found in the vehicle. There are some other goodies that I do use that have increase mileage even more but don’t have time to discuss it.

     Alright guys, first of all, we all know that experience is worth more than other people’s 2 cents. That being said, everyone posting on here should either be trying this or have documented information. No one on here cares about everyone’s opinion on the matter. I work at Volkswagen of America so I have hands on experience on fuel emissions and consumption daily. First of all, carbs don’t simply mix fuel to air so that they are 14.7 to 1. They also emulsify and atomise the fuel. This is extremely important. Liquid fuel does not burn. It is the vapor or gas surrounding the fuel that actually burns. Therefore, any chemical that aids in vaporising the fuel or encouraging it to be airborne will aid in the effieciency of the engine. Power, throttle respose, and fuel consumption are all part of engine performance. Also, I read this somewhere, nitrous does not lower the temperature of the fuel. The main engines face is volumetric effiecency. In other words, pulling motor into the combustion chamber and then pulling it out. Nitrous is basically compressed oxegen so that the motor doesn’t have to pull the air in, it is rather injected. The other half of this issue is that the mixture has to be just right. The articles I have read say that 1-3 oz our good so when I read that guys are throwing unmetered amounts of acetone in the tank and not seeing a difference, I think that can be blamed on them. I have started this test 3 days ago and have not filled up yet to analyze the results. I think everyone should stop arguing and trying to out-do eachother and just do a little research.

146. drive a hybrid says:

     I have a hybrid and my wife has a gas hog. I regularly get 45+ mpg in my hybrid while my wife gets less than 20 mpg. We recently switched cars and my wife was only able to achieve 32 mpg in my hybrid while I got over 30 mpg in her hog. How could this be??? not acetone, not any additive just driving style. Try coasting down hills, allow your car to slow down while climbing hills (the traffic behind you - screw them). You could try stopping the engine at red lights like my hybrid but might wear out the starter after a while (I didn’t do this). Also try to find a route that is less hilly it may have more miles but if your engine isn’t working as hard to get you from point A to B then chances are that you can catch a couple of mpg.

     Acetone increased my toyota,s mph by 5 mpg . As far as acetone dissolving parts take a look at fuel additives like B12 and STP or others open them up and smell them and you find that sweet smell of Acetone. I use about 2 oz per 10 g and 5 mpg increase.

     I’m with James on this. Too many opinions and not enough testing. I see a lot of people saying that it will mess with the o rings or the fuel lines or other parts. How ever I have never read yet where anyone has confirmed that.

     I have a 2000 Pontiac Montana and I am going to add acetone on my next fill up. The Montana holds 25 gallons so I will start off with trying only around 3 oz for the tank and will increase it to 2 oz per 10 gal and then 3 oz. per 10 gal. I will keep records and come back and post after each tank of gas. Currently I am getting around 20 - 25 mpg with mostly highway driving. After 3 tanks of gas I should have a good idea if this is going to work or not. If it does not work I am out a few bucks for the acetone and then won’t use it any more. But I am sure that it will work. I’m hoping for at least 5 mpg. I may only add the acetone every other tank and see what that does too.

     Thanks Gene,

     It has been a few weeks now. The first fill up I got 28.5 MPG compared to my usual 23-24. My second fill up I got about 27 mpg. I am trying different ratios ranging from 1.5 oz to 10 gallons to 3 oz to 10 gallons. I will try to keep this site updated with my findings. I have not noticed any increase in performance or throttle response.

     re Less Cynical than YOU comments…

     Re the carburetors and FI efficiencies I agree whenever I have bought a new car I have been very lucky and seem to always have receive the car with the secret testing stuff on it (LOL). Really my 1988 Cavalier loaded with 7 cases of beer hundreds of lbs of camping equipment inside, in the trunk and on the car got well over 40mpg. Not loaded like that it got much higher and it was rated at only 26-28 mpg. I should have never scrapped it.

     My 2002 Saturn Vue was rated at 24-26 hwy and loaded when I drive non aggressively gets 40+ without acetone…these values are better than today’s hybrids…so there are obviously things the manufacture can be doing and are not… and I am still going to try the acetone because of my understanding of chemistry I know that there should be at least some increase in mpg…

     Funny thing is I’ve actually improved my MPG just by changing the EFI parameters in my EEC. If this thing will show you my link I have a few Mustangs. I tune them with a product called a Tweecer R/T. (Real time datalogging). I have picked up 2mpg on my 50 minute commute of 70-85mph 4 lane speeds mixed with 10 minutes of city traffic and stop lights.

     I’d provide links but you can google the products I’m talking about as I’m not advertising for them.

     The reason I’m here? A friend of mine HAS tried this instead of saying what it will or wont do and he has noticed 4 mpg improvement in his civic. He only gave $1500 for it. I refuse to listen to someone who never did it either way. Do it and say no, or do it and say yes. Otherwise why bother trying to influence anyone, yay or nay?

     So… I’m trying it in my Mustang. Why? Because I built my current projects from the ground up. I have no concerns over the plastics because hey, if they disolve big deal. I’ve got more.

     I can FULLY datalog the improvement in progress at the end of each trip without having to pull up to a pump. How? Just like Mythbusters did with the 18 wheeler drafting test.

     If you don’t believe me I can send you screen shots of the changes.

     So far my changes have been to activate DECEL strategy in the A9P Ford Processor. At load values below 17 and RPM’s above 1200 the PW’s (injector pulsewidths) drop to 0.00. I’m also working with EGR scaling so that I don’t have as much engine drag and pumping losses. I have been able to rescale the engine loads (sea level load scaling -VE tables) and properly curve my MAF (Mass Air Flow meter) for my parts combination.

     Keywords you can search on are…
     Binary Editor
     EEC Analyzer
     Tweecer
     EEC Tuner
     EEC Tuning
     …and combinations of those terms in one search line.

     There are also at least 3 yahoo user groups

     You will find a group of people who actualy test, test, test and test some more. Instead of sitting behind a keyboard wondering about it or telling people their car is getting 250mpg on using watermelon seeds and twinkie wrappers as a joke.

     To certify my lack of concern for damage by Acetone if this posting does show you my website and you view my engine build I can show you the build sheet that outlines the cost in excess of $9644 just for the motor.

     I try to be objective either way. I also belong to a group of people who just 7 years ago exclaimed we would never see a 7.40 ET on TRUE RADIAL tires through the 1/8th mile.

     WE are now eating crow! We have people who have surpassed that by a large margin. We also have in our group a NMRA Drag Radial champion who won last year and set a new world record in the process. He did so with an 8.13 1/4 mile pass in a street car runing DOT drag radial tires at over 175mph.

     This year? He’s already gone 8.02.

     The point? People said it couldnt be done but never tried it until he actually did it. Now everyone is doing it.

     The world used to be flat too…

     Round 1. I decided to test it. I was never much on being in a race with no horse. READ: until you try it, why not shut your pie hole either way? I mean seriously, how credible can your information be- um, on either side of the discussion?

     That said I spent the last few weeks pulling data logs and base lines from my car. I ended up going open loop for economy because the factory O2 sensors hold me to 14.7 and I wanted to go lean as possible regardless of emissions. Sue me for poluting..

     Anyhow I ended up with a combination confirmed on my wide band O2 that is between 15.8 and 17.5 AFR on cruise loads. After dialing in my injector slops verses my Mass Air Sensor (89 Mustang). Keep in mind Ford uses something called adaptive control that updates KAM (keep alive memory) for corrections to it’s AFR for closed loop operation.

     Long boring story short for you non technical type let me say I’m full time open loop, no adaptive control or corrective action from the EEC can occur. This means one thing. A perfectly running car verified by a perfectly operating wide band O2 sensor confirming commanded air fuel ratio.

     I can also data log mpg but lets not go there yet.

     First you should know that I’m running 3oz in a 16 gallon tank.

     I run 87 Octane only.

     I have confirmed ACETONE has caused my wide band to show 2 points richer than commanded AFR (air fuel ratio).

     What does this mean? Well all things being equal, and considering I have disabled lambda correction that means the EEC has no clue I have done anything to it’s fuel. Meaning it is commanding the same AFR but I’m getting a DIFFERENT (richer) result on the wide band O2 sensor.

     Richer = unburned fuel.

     But hold on. Wasnt ACETONE supposed to cure that? Wait, theres more. ACETONE increases the octane of fuel, in this case about .3 points. So in effect I’ve experienced going from 87 to 90 octane with 3oz of acetone.

     Do you know that octane slows down the burn process? That much is obvious. Why is it obvious? Well as an Air Force Fuel specialist I konw that octane basically raises the fuels flashpoint.

     Still confused? Ok, HEAT is an essential element to have fire. You need 3 things. Fuel, heat, and oxygen. Remove one, and no fire. Doubt me? Look at your shirt, it is fuel, and you are breathing air, no fire. So your surrounding AFR won’t support combustion.

     Still with me? If the AFR inside your engine is too rich or too lean your engine wont run either. Too much fuel is too rich. Consider that the next time you BBQ and close the lid and smoke out your grill and flame. Plenty of everything except air…

     So back to the MPG increase or not. Well I’ve told you I am running richer than my “normal” baseline. That is where I am right now. So I’ll recurve my OL fuel table. Why? Because for instance you might already know E85 runs a richer AFR than gas, right?

     So I’ll respost when I get that done…

     Meanwhile that is a result. A difference. Left alone with out recalibrating the fuel tables would in my instance mean I’m either not going to see a difference, or get worse mpg.

     Seriously though to those who havent tried a thing, why not shut up? I could care less if you get 2 mpg. The argument here is, the world was flat until someone got off his lazy arse and went to have a look!

     I mean if nothing else, 3 oz of acetone has only increased my octane rating to an engine that doesnt require it but if it did, is that 3 oz cheaper than the higher grade of gas? Would I have known this if I just sat here laughing at Christopher Columbus?

     Stay tuned…

WHAT NOT TO DO: Engine and Fuel Additives, Alternate Fuels, and "Miracle" Products Various unproven products to improve vehicle fuel economy have been reported ranging from magnets that align molecules to chemical combustion improvers. Most products claiming to provide benefits are based on unsubstantiated claims. Those that do present "scientific" results generally either have too little supporting data to be conclusive, have not conducted experiments in a controlled fashion, or cannot be substantiated by anyone else but the product’s manufacturer. The U.S. Federal Trade Commission summarizes results for products tested by the federal government at FTC Bureau of Consumer Protection. A review of the list shows that the majority did not work, and for those that showed some effect, the benefit was too small to be cost effective. Harmful Ideas That May Damage Your Vehicle and Increase Emissions One more recent poor idea to improve fuel economy that should not be attempted is to blend either kerosene or diesel fuel into gasoline. Why? Both kerosene and diesel fuel are distillate fuels meant for use in compression ignition engines, not spark ignition engines. They have very low octane and since they are heavier (higher density) than gasoline, they will cause heavy engine deposits and degradation of engine oil. Notice: Never put Kerosene or Diesel Fuel in your Gasoline Engine vehicle. This may result in inconsistent performance and permanent damage to your vehicle that is not covered by your New Vehicle Warranty. Notice: Never use acetone, ketones, or methanol additives in your vehicle. Some of these solvents may damage or corrode your fuel system. They are also very damaging to the painted surfaces of the vehicle if spilled. Chemicals that are normally used as solvents also should not be used. These include acetone, ketones, and methanol. These solvents can be incompatible with your vehicles rubber or sealing components, and may dissolve the vehicle�s paint finish.

     It doesn’t work, it’s that simple. Many have tried and generally the more presice the measurments the less improvment is seen from Acetone.

     I have a theory that if your engine is in really really bad shape the acetone might clean it up to the point where you get a few extra mpg.

     It shouldn’t be harmful to try at least, you only lose the cost of the acetone.

     Scientific Methods

     Science does not need to be done in an expensive highly controlled laboratory for it to be sound. Most scientific discoveries happened far from a lab. It is desirable to be able to control all the variables however, it is not always possible. The heart of any experiment is to focus on a point of interest, test it, and then observe the results. The best part of science is when someone does discover something new or provides new insight from experimental observations. The recording of the experiment allows others (peers) to replicate the experiment and observe the results for themselves, either confirming or disproving. It does not matter either way (approve or disprove)… that is the scientific method. Before science accepts new ideas or findings, the subject is usually proved thousands of times. Often initial experiments warrant further investigation and more detailed experiments.

     So before you flap your trap (sound like a ‘tard) on the subject, document your own experiment, quantify the results and comment.

     As an after thought, if you cannot confirm the results claimed, perhaps you should think about why the claimant was successful in their experiment and why yours failed (this is very important, because you may have just discovered why the claim is false or why your experiment failed as well-this usually can be found in the variables).

     Acetone used in Gasoline - Numbers do not Lie

     A few notes about acetone. Acetone is NOT CORROSIVE. Acetone is NOT TOXIC (do not drink it of course). Acetone will not harm good fuel line components and can be stored in HDPE plastics. Anyone worried about acetone in their fuel can do a 30 second Google search for gasoline formulations and you will see Shell’s formula allows 0-10% acetone. (I suspect actual product is around 0%).

     My observations:

     I have kept detailed records of my vehicle’s mileage for years. I own an ‘88 Dodge Dakota, V6, 5spd, 4×4 and typically got around 18mpg city/25 mpg highway. I was satisfied with this economy for this vehicle. I replaced this vehicle with a ‘97 model with the same powertrain. I was really disappointed when I was only getting 13 mpg city/18mpg highway. This vehicle was 10 yrs newer and was only getting 2/3 of the mileage. I had the truck into the dealer several times to complain of high fuel consumption; each time I was told there is nothing wrong with the truck. I tried replacing filters, o2 sensors, etc: No help. From discussions with many people, the mileage of my ‘97 truck is typical and within specified ranges (lower at beginning and upper after improvements). So much for technology advancements.

     I always felt the engine was running too rich. The exhaust always smelled of unburned fuel. In cold weather it would be hard to start and flood. My thinking on this was that the engine needed more air to lean out the mixture. As such, I modified the air intake to allow more air flow (essentially a ram air set up where vehicle speed will provide positive air pressure to the throttle). This improved my economy (&power) by about 4 mpg (17 city/22 hwy). I ran the vehicle this way for 4 yrs. Record mileage on highway was 23 mpg. Quite happy with the improvement. Results varied little. Documented to prove results.

     This year I began looking for other ways to improve mileage as I was still getting less than my old truck. I found the idea of adding acetone to fuel. I was skeptical of the claims (I’m an engineer and I doubt everything until I see it proven). But for $8 I bought a quart of acetone and tried it in the prescribed amount. In the first tankful, I was wowed. I saw a 15% increase in my mileage (up to 20mpg city). I really wanted to get my truck on the highway (driving is less variable than in the city) and try out the mixture. My first tankful on the highway (3rd tank with acetone) I reached a record 26.5 mpg. I’ve just finished my 9th tank of fuel with acetone and just completed another record of 29.5 mpg on the highway. This is a rate I never expected or could believe possible. My mileage is still increasing with each tankful. I’m curious as to where it will top out. To date acetone added to gasoline has increased my mileage 7+ mpg on highway.

     I have also tried acetone in my Jaguar X-type. I observed an improvement from 34 mpg best ever to over 40 mpg in the first tank.

     I have other plans to increase mileage, but I have yet to quantify the effects of acetone alone. When I see my mileage stabilize around repeatable numbers, I will try my next experiment.

     Other observations with acetone use:
     - tailpipe smell seems to have cleared up
     - engine does not cough/choke/sputter at low rpm
     - better idle
     - reduced knock

     My conclusions:

     I expect you can see mileage improvement up to 30% with acetone use alone (as prescribed) in your gasoline powered car. Most people should expect a 10-15% improvement. You might have to tinker a bit with the mixture to get the best results.

     Comments on Octane Rating of Gasoline

     I have seen several misunderstandings about gasoline written here and in other forums.

     Octane rating is a misnomer. It should be called Antiknock rating. The rating number of the gasoline has nothing to do with engine performance, power, or economy. If you buy high octane rated fuel for these reasons you are giving your money away to the oil companies. People have the perception that a higher number equals higher quality or performance. WRONG!!! (I should be in the business of selling 200 octane fuel to all those reading this and thinking I’m stupid).

     Read your owners manual. Use the fuel specified. Your engine was designed for that.

     Here is what the octane rating means. It is the ability of the gasoline to prevent autoignition (higher flash point). If you are experiencing knock, try one octane rating higher. It should clear up. You can also try colder spark plugs.

     The reason to use higher octane rated fuels is for engines with higher combustion temperatures such as higher compression (heavily modified mechanical - crank, rods, pistons, heads) or engines with boost (superchargers & turbochargers). These conditions create higher temperatures at compression and need fuel more resistant to autoignition.

     Best fuel economy comes from gasoline that is really close to knocking or pinging in your engine. Higher octane rated fuels actually have LOWER fuel economy and LESS POWER for your car. The reason for this that the higher octane rated fuel is more difficult to burn. It is harder to ignite and more difficult to keep the flame front active. It also results in more unburned fuel leaving your engine.

     Some people have asked what F1 uses for fuel. It is a highly guarded secret of course. I have heard once that it is 85% toluene and 15% n-heptane. The n-heptane is used as filler to keep the fuel within IAF rules. I would recommend against using aromatics in your fuel as they are known to be hazardous to your health.

     Acetone, as I’ve been told, has been used as a racing fuel additive for nearly 50 years. Pure it is 150 octane rating (see, there is no octane in acetone, but it has an octane rating). Adding acetone to your fuel should increase the octane rating (although slightly). In observations it represses knock and many people report that they can use one octane rating lower fuel in the same car. So not only does acetone improve mileage, you can buy cheaper fuel. The benefits to the wallet seem obvious.

169. J.D. says:

     I agree that you may not necessarily need to eliminate every variable for a test to be believable. Simple statistical analysis can be used to track the repeatability of an experiment. The more repeatable the experiment is, the more believable your results become. For you people tracking many tanks of gas, record your mpg on each tank and figure your mean, average, and standard deviation. These are easily calculated using Microsoft Excel.
     For best results with statistical analysis, you will want a fairly large data set (greater than 6 but does not need to be greater than 60) of mpg using acetone and a data set with the same number of points not using acetone. For instance: find the mpg for 10 tanks of gas with acetone, and then for 10 tanks without. Then use the data you collected to calculate the mean, average, and standard deviation.
     If the “personal testimonials” on this blog are true, the mean and the average mpg will be higher in the data set where you used acetone. The reason why I included the standard deviation, is because that is a measure of how repeatable each data point is. A small standard deviation states that all data points are very close to the mean. A larger standard deviation states that the data points are more likely to fall farther away from the mean. Some variation is common for any system, but wild variation just means that your experiment is unrepeatable, and thus unbelievable.
     If anyone is confused by this, Wikipedia probably has a better explanation of basic statistics. Hope this helps…

     2. some info on mileage gain usage of acetone in a carburetor engine?

     Wow! what a huge number of different opinions and results. Me now, I live in Albuquerque where the regular gas is 86 octane (and I really don’t know why). Anyhow, my 2006 Impala is an E85 fuel compliant vehicle. The dealer recently did the E85 reflash on my computer and this added 2 to 3 MPG to my all around mileage. My question is: Since my vehicle came with all the SS tank and lines, would adding acetone (in 3 to 4 ounce quanities) to E85 “corn squeezins” raise the performance and octane levels enough to run the stuff? I presently get 30+ MPG on the highway, GM says that E85 will drop that to 24 (or less). See whrer I’m going with this? Comments please.

     I have a 2006 BMW 330i.

     I tested the “Acetone” theory and I found that, previously, in city I sued to get about 21-22 MPG….after I put the first 10 gallons of fuel, I went to an average of 29 MPG. The lowest I registered in city was 27 MPG.

     I can’t wait to take it for a long trip. My Bimmer has already reached 35 MPG before on log trips, before I found this acetone thing, so know I want to tested on a long trip to see what happens.

     I believe it does work!

     November 12th, 2007 at 10:45 am

179. Chuck says:

     ok.. time to put an end to this blog. The reason why some people see “results”, and others cry about not are they haven’t tried acetone, or, they have a low compression car and a weak computer program. For example, my current car has a 10.3 to 1 compression ratio and i use 87 octane gas(which, the owners manual surely says to use minimally 91).. However, the car runs and i am cheap. If acetone does what people say it does and produce a higher “flash point” to the fuel, i have very very very cheaply increased the octane rating of my car. And, U can see why “big oil” doesn’t want this trick to get out, because then they would not be able to sell their high octane fuel anymore at at least a 40 to 50 dent more a GALLON price than good ole crappy 87!.. Now, how does it take 3 to 4 tank fulls for it to work?.. Your computer in your car adjusts to the fuel quality in the tank. And, also, surely acetone is also cleaning out the cylinder chamber also, allowing the computer to advance the timing and produce max “push” from the gas without detonating. That is why across the board you will see big engines making the most gains from it. Because as the piston increases diameter, it becomes very easy to “detonate” cheaper or lower quality fuel. Thus, even without the computer increasing timing, a big engine almost gains power and gas mileage instantly. Once i had a 74 cutlass, and thought i was losing power and someone asked me if i ever had put high octane fuel in my car. Well, i tried it and it seemed like i had a TURBOCHARGER in it, even at only a 8.5 to 1 compression ratio because i was the computer, and i had already manually adjusted it for a n aggressive advance curve!.. So, acetone isn’t a miracle, and i am not soo sure about its “magical vaporization’ or its other claims that only anger logical people. However, any gear head can tell you that if you buy an aftermarket chip for your car, and use the recommended 93 octane for it instead of the crap gas u were using previously to take advantage of the newer timing, your car not only is more powerfull, but if you could keep your lead foot out of it, you would get the average 2 to 9 more mpg that cars are getting. Oh, to “speed up” the process?.. Simply disconnect your battery for 30 seconds or so to reset your comptuer. After it comes out of closed loop operation you should have max power curve to run with acetone. And again if you have a 8.5 to 1 or lower compression car, and the cars requirements for octane are only 87, then any higher octane or octane booster would be simply a waste of money UNLESS you could obtain a aftermarket chip that reworked the advance curves aggressively enough to make more power out of the higher octane. And, this is ALSO why when you add TOO MUCH acetone, your results and gas mileage GOES DOWN.. Because, if you add too much octane that your low compression engine can not utilize quickly enough, raw fuel will exit out of the exhaust and flow down into your oil. So, hope this helps to understand what is happeninng and even the pussycats that are afraid of putting an oz of anything in their tank thinking the world will come to an end, hope U guys can grow some.

186. Melissa you Twit! says:

     Melissa, that is because your engine sensors were so gummed up that when you added acetone to your fuel, it cleaned them off! Just as all the INTELLIGENT people above (the ones that REALLY work on cars, not the ones that forgot to line their helmets with tin foil like we told them to) stated up above, any fuel injector/carburetor cleaner would have done the same thing. If you clean out your engine with any fuel injector/carburetor cleaner (or acetone) & drive with the same driving habits consistently (impossible to do accurately), you will find that you are going to be getting better gas mileage without any additives!

How can they, in one episode, have enough quantitative, scientific data presented to completely lead you (the sheep) into believing Acetone has NO effect on any part of the combustion cycle of gasoline? They are in the entertainment business guys! You would have been bored off your butt had they spent the time needed for proper laboratory analysis in this case.

     I have a 2001 chevy tracker with 130000 on it. It is a 4 cylinder 2.0. When I got it new I only checked the mileage on trips because gas was cheaper. Best highway mileage was 31 then. Recently I checked the mileage and it was down to 26-27. I started putting two and one half ounces per ten gallons of gas. The gas has ethonal in it. I have checked the last 9 tanks of gas. My combined city and highway averages 29-32. Highway mileage only averages 34-35. I noticed immediate improvement in idle and smoothness of engine. On the highway I drive 65 to 70 with cruise on. I did this before I started putting acetone in. For all I know it may have just cleaned the injectors. I also put the acetone in the tank after I fill it up and drive it home. I use a 60 ml. plastic surrenge with a rubber boot on the end. That’s 7.5 ml. per galllon. It also has not melted like everyone says it would. Granted acetone will melt paint if you leave it on long enough but if you are not smart enough to get it in you tank without dumping all over your car you probably shoundn’t be driving anyways. I have been using acetone for years as a cleaning solvent and if by some chance you do happen to get some on the paint dab it off with a towel before it can react with the paint and you will never know you spilled it. I buy the acetone from my local hardware store. Most of the people I told about doing this have started using it in their cars. Guess what they all had positive results. I will continue to use it.

Those that did not see an increase, don’t know how to check there mileage correctly or are just plain stupid! It will work with any car any engine. Melt your nylon or plastic parts? I dought it very much, too much gas mixed with the acetone to do that. Next I’ll check it with new spark plugs, then with a fuel heater and other improvements…..

After adding acetone mileage improved, could we also speculate that the acetone cleaned or removed carbon/gunk build up and now they are seeing a better running engine that is back to the should? I would like to see someone test it on a new car that has not be subjected to the years of fuel and oil wear. Since I do not own a car newer than 1999 I could not do this test.

What made me nervous service engine soon light came on. Started adding 2-1/2 ounces to ten gallons of gas again. Mileage went back up. Check engine light went out after second tank with acetone. The only reason I stopped using it is I ran out and to dam lazy to stop at home depot and get more. Bought a gallon this time. I am going to try 3 ounces per ten gallons and document the results. After I figure out the optimum ounces per gallon I am going to mess around with the hydrogen generator.

As for the IGNORANT Tree Hugger thats 3 gals gas exhaust vs 2 oz acetone. Don’t have to be a genius to figure that out. Acetone does not work for EVERYONE’s car, my Dad’s 2007 Dakota 3.7 V6 does not see any improvements in mileage so I know it doesn’t work for all cars. Another thing, it takes 2-3 tanks of before you see improved mpg so the MythBusters experiment was FALSE as they only drove the car a few miles not a few tanks as recommended. Hydrogen SAFER? Isn’t that what they used to make BOMBS out of and the fuel used in the Space Shuttle. Acetone doesn’t make old engines run as they should, it makes them run BETTER than they should.

     My 1991 Plymouth Acclaim 4-cylinder automatic is EPA-rated at 26 highway, 21 city, and that’s about what I was getting. With 3-oz of acetone in a full tank(about 14 gallins), I’m getting 30 highway, 25 city. Not to mention the car runs smoother. Pretty impressive!

224. Acetone Fanatic says:

     I have been using 3-4 oz of acetone off and on for about six months now. I have found that it does in fact increase your gas mileage fairly dramatically. I have noticed about 20%-30% reduction depending on the outside temp and air pressure in my tires. The technique I have found to work best is to add the Acetone before a fill up when you still have at least a 1/4 tank of gas. I have no idea why but that technique seems to work. One thing to look out for is additives in the acetone such as moisturizers, fragrance and other additives. One reason that I have read that it works is that the acetone decreases the surface tension of the gasoline allowing it vaporize more easily. I think the impact may be greater on older vehicles as they are the ones more likely not to be running at full capacity. I say give it a try, my family thinks it’s crazy but they envy my mileage.

     i would use acitone along with a water injector. the acitone for fuel breakdown and the water for super cooling the chamber.
     this way can have power and performance. you can also put a rev limiter that sends a electric shock to the driver seat, once you rev to high the spark burns your rear. danger too much personal gas in drivers area could cause explosion. maybe send that captured gas to a charcoal canister and burn it with a nos nosle hidden in the intake manifold.

     acetone is much more explosive than gasoline and thinner, so duh

     Plain & simple this “miracle additive” can be tested accurately using a dynamometer, a machine made specifically to test exactly this type of claim.
     see: “http://en.wikipedia.org/wiki/Dynamometer”

     Until it is tested & proven in a controlled environment using a dynamometer, all of your claims are purely unscientific & a bunch of hogwash!!!!!

     All of your first person claims are totally worthless, as there are WAY TOO MANY variables involved in driving!

     PT Barnum was right: There’s a sucker born every minute!!!!!

     Anybody wanna buy a bridge?

228. Acetone Forever - Not! says:

     The Hummer dealers recommend that you do this from the moment you drive off the lot.

     Once you have left their premises, you own the vehicle and any modifications you make to it void your warranty.

     So when you come back in with a fried engine from using acetone, they can charge you about $10,000 to fix it up.

     Oh - Have A Nice Day, Pinheads!

     We need more skeptics to keep giving the oil companies more of their hard earned pennies. With the price of fuel dropping fast, our precious oil producers are needing all the help they can get.

     By the way, if you want to buy pure acetone, look on the container label for the designation of ‘USP’, or ‘CP’, it means that the product is chemicaly pure.
     The best source I’ve found is the paint department at hardwares, home centers, or farm stores.
     Some places you can even get 5 gal cans of it.
     Of intrest; Any gain in milage above about 3 % will start to get cost effective.

     Looks like there are pros and cons. I will give it a try and if it works, great. I have 3700 mile trip to test it. will be testing on a 1990 ford van starting mpg is 11mpg. I will post results around the 1 st of April. Nothing ventured nothing gained. Lets hope the outcome will be an improvement. I cannot control the gas I buy, with a limited range I have tobuy at the closet station when gas is low. However the baseline is from the same trip eastbound. I will be trying to duplicate the return trip exactly the same. Not accounting for the earths rotation. Hope it will work out.
     It’s going to take about 15 tanks of gas, and it’s going to be a fair test. Not going to bull shit myself or anyone else. Back at you in April.

236. You Acetone Users Are Absolutely Retarded! says:

     The is no point in arguing with a retard like you Acetone users - facts just get in the way of your argument!!!

     If you would only line the inside of your helmets with tin foil like we told you to, you wouldn’t keep hearing these voices telling you to do these asinine things!!!!!

     I have a 2001 Dodge Stratus, I believe that acetone works, here is what I did to my car:
     1.changed the air filter bought it at Walmart
     2. I bought the Halo Spark Plugs
     3. I bought synthetic oil
     4. tire pressure is at optimal
     5. lastly, I drilled small little holes in the front end bumper of my car in the direction of the opening of the air intake, this works in the following way as I am driving my car let’s say 65 mph the air that is coming into contact with my front end bumper is being carried in, directly into the opening of the air intake (blast ), I do not have an after market air filter , I used a plain air filter from walmart , the purpose of doing this is to allow more air perhaps more oxygen in my car the results are great, breathing

     I also added to my fuel tank 2 oz of acetone, at every gas fill up. I use it. I think I am pushing 33 mpg

     Hi, I’ve heard of it about 2 years ago and I did not belive it, but, when gas prices went u, I took it seriously. finally last month I tried it on my v6 chevy malibu 1998 wich I had an avg of 17-19 (combined city and highway) and my milage went up for an avg of 27 mpg with 3oz/13 galons gas tank, now I’m going to try hho gas.

     Now If I don’t add acetone in one tank, my milage is still over the previous I used to have, I get avg of 22mpg without anymore additives. its been over a month and the spark plugs are clean, the oil went really dar at first, but when i changed it, it looks a lot better than before and it fells almost as thick as new.

     So far I research that may not work on all car because of the computer and the o2 sensors
