acetone
My dad told me he was reading up on fuel-saving tips and tricks and one of them he came across said to add 3 oz of acetone to an almost empty tank and then fill the rest of the tank with regular pump gas (as a fuel additive). He was wondering what kind of effects it would have on naturally aspirated or forced induction engines (as far as the actual improvement in the fuel efficiency and performance). I was curious about acetone injection.

Acetone
Like many urban legends the idea of using Acetone in fuels has some small basis in fact and a lot of bad science or at least missundertanding of basic chemical and engineering principles.
Acetone is a Ketone CH3-CO-CH3, it is a very powerful solvent, used in paint/laquers, nail polish remover, and frequently used in industry to completely degrease components. It has very high cleaning power and will quickly degrade many rubber like fuel system components. In very small amounts it can help clean dirty fuel injectors due to its very high cleaning power. That said, it is quite similar to alcohols in some of its characteristics. It is miscible with water, and is highly flamable, having a lower explosive limit than ethanol or methanol at 2.6%. The alcohols however have higher upper explosive limits and will burn at richer mixtures. It was used in small quantities in some exotic fuel blends during the hey day of racing in the early 1900's. My best informantion is that it was added to increase burning speed of the fuel air mix and suppress pre-ignition in lean fuel mixture. I can't find any reliable info on its octane rating.

Due to its very high solvent cleaning action, it should not be used in large quantities in normal fuel systems due to possible problems with degradation of rubber hoses and seals / gaskets / O rings etc. Acetone has a reasonable octane ( like the alcohols in the 100+ range) but has been used in some exotic racing fuels more to help control pre-igniton, and increase burn speed, than to contol detonation when running very lean fuel mixtures. (lean mixtures make good power and are important to racers who must make pit stops for fuel during the race. Reduced fuel consuption means less fuel to carry.) Larry |

Found this on a volvo forum:
http://www.lubedev.com/smartgas/additive.htm and http://www.peswiki.com/index.php/Dir..._Fuel_Additive Who's willing to try this

FWIW, I tried 4 oz in my 14 gallon tank, 1996 Ford Mustang coupe, 3.8L V6.
No changes noted at all in regards to mileage or power. I put 206 miles each way in my commute to work and I know exactly what kind of mileage I get, 25 mpg, which is exactly what I get with the acetone added or without it. So no improvement here. |

My uncle drove from long beach, ca to phoenix, az on one 12 gallon tank of gas in his VW Fox. He said he was never able to get that kind of milage ever. Tomorrow I am going to try 3 fl oz of acetone for the 10 gallon tank in my '93 ford festiva. I already get close to 40 mpg, but It would be nice to up that number. I am astill curious about using acetone for wi in my turbocharged saab. Say, instead of my 50/50 setup of water to alcohol, i'll add 0.75 fl oz of acetone to my 2.5 gallon wi resivoire. In my Saab I am looking for power gains, not necessarily milage. Just a thought

Whats up uberfast?If you decide to try out the acetone,wich I was told to stay away from solvents,I forgot why but its in my old posts somewhere--anyway theres a fuel made for alchohol burning stoves called SOOT FREE BRAND wich has a little Acetone in it and is advertised to burn cleaner than straight Alky.Maybe they achieve this with the acetone.I bought some at one of those major marine supply stores.the cost was the same as regular Alky.just wanted to let you know about it.
