i dont think it will work. first of all, i think acetone and hydrocarbons (gasoline) are immiscible..... but aside from that, gasoline has very little surface tension to begin with, and acetone is just way too volatile to really help. they say to add a little in, but ive dumped about 1/4 cup of the stuff on the counter in the chem lab just for fun to watch it evaporate over the course of about 20 sec. they say to add very little, by the time u get to capping it, uve probably already lost most of it (thats assuming you can get polar and covalent fluids to mix...)

i think the term you are looking for is polar and nonpolar. hydrcarbons, such as gasoline, are theoretically long strands of carbon atoms whch are saturated with hydrogen. in reality, the primary constituents of gasoline are hexane and benzene. typically, these molecules will have two forces which bind them to on another; london forces and induced dipole, both of which are very weak attractive forces. since there is the existence of induced dipole in hydrocarbon molecules, acetone will be slightly miscible in gasoline. that's why you can't add too much, it won't mix.
as an interesting side note, i want to debunk the octane myth. higher octane fuel is not more combustible than lower octane fuel-quite the opposite. higher octane fuels are harder to combust, which is why higher octane fuel will resist detonation. the octane rating we use just refers to the fuels ability to resist detonation. so by purchasing octane booster and high octane pump gas, what you are actually doing is using a fuel that is less combustible. the myth that i am debunking here is that you will get better gas mileage with higher octane fuels. patently not true. the higher octane just allows you to use more advanced timing without the fear of detonation, THERE IS NOT INCREASE IN FUEL ECONOMY.
as another interesting side note, try mixing equal parts acetone and nitric acid. please do so from a distance. there is another name for this particular mixture: rocket fuel.

I took the chance and put it in my 95 escort beater car gets 40 mpg anyway but more is better I used 2oz to 10 gal I did not see much of a diff. but it did run better and the slight spark knock it has went away. ran that gas out put straight gas in and spark knock is back I will put less acetone in it 1.5 oz per 10 gal. of gas. I also got brave and put it in the wife everyday drive 2000 mustang v6 and I can tell you this it is on a record for mileage as of now I mean huge gains it gets around 170 miles to a half of tank and has got 214 this time and that was 2oz to 15 gals and the car runs better also. So it is working in one and not the other I think I got to much in the escort and that is why I have not seen big changes. the P/S Ford truck is next. I do think it is helping mileage and I know it is making them run better. But I can fix any thing I break up so that does make a diff. in tiring something

if u increase ur timing there is an incerease in mileage with higher octane fuels!!!! and the engine will run cooler and operate smoother!!

i actually heard of this. back when i was trying to decide what car to buy, i was on the wrx-sti path for awhile and i read that you put a gallon or pint or liter or quart or can or bottle or bucket or shot glass or mug of the stuff, cant remember, in each time you fill up, acts like a serious octane boost and gives you a minty fresh exhaust smell.

just fyi......Mythbusters proved that acetone in the gas tank to increase mileage was absolute crap. It actually made the fuel burn more quickly, decreasing the mileage. It ironically was on last night after I had spent the afternoon reading you guys discussing it on here, so it was cool to watch them "bust" the myth. They proved it in a vehicle with carb and with fuel injection...no gain what so ever, in fact made it worse.

did they try it w/ varying amounts? That's strange since some people swear it's been workig for them.....

Well I watched mythbusters last night and they busted, absolutely made no difference, seems like a self fulfilling prophecy for everyone that says that it worked, they even ran it on a dyno. It's amazing how a diesel motor can run on straight filtered used vegetable oil with only losing 3 mpg.
