Acetone will eat any rubber/plastic/composite material completely.

Not quite true....near as I have been able to research, acetone was used in racing in the 50/60's with little ill effects on the parts. It some cases, it's still used in racing today.

Acetone is not as hard on rubber, viton and buna-n as gasoline.

It won't disolve polystyrene and similar substances like gasoline will and it breaks up the surface tension of gasoline, the oposite of alcohols.

It will attack certain plastics, but not those uses as fuel tanks or tank floats.

Acetone is actually a byproduct of making phenols and considered about one step better than waste, which keeps the price down.

Acetone is biodegradable, completely safe if it ends up in ground water, where it quickly degrades.

OK, use all the acetone you want and void any warranty you have remaining on your auto. If acetone was meant for our current fuel systems, it would be added by the refinery. Auto manufactures are looking for any help meeting fuel economy standards, and if acetone were any easy answer, it would be added.
