Total BS.
The tricks to improving your gas milage are as follows:
1) A clean air filter
2) Properly inflated tires
3) Spark plugs and wires in good condition
4) properly working, clean fuel injectors
Another one that works really well is a LIGHT right foot!!

.... it just doesnt add up to me. i could very well be wrong, but i play with chemicals all the time, and this idea is not really adding up to me. first of all, acetone is a wicked polar solvent. that makes me worry about all the plastics in a car it may come in contact with, which it would dissolve (ie. fuel delivery!!!) . second, if it's so great, why isn't it in gas already? third, it evaporates extremely quickly, so i think the effects would be short lived. my general impression is that it may (at best) act as a cleaner for the first few miles since it's a great solvent, but after that i think it will have left the system.... i'm going to check whats in my fuel injector cleaner tomorrow!Even if it doesn't give you any increase, it will keep your fuel system clean. For the people that think this will hurt the fuel system, dream on...2 to 3 ounce for 1280 ounces of gas (10 gallons)...the ratio is rediculosly small. Fuel injector cleaner is about the same quantity.
