Acetone's a solvent in the same class with toluene, benzene, naptha - pretty strong medicine. They're all hard on rubber and most plastics. It may have a future as an additive (if the EPA doesn't put the brakes to it), but I'd avoid adding it to motor fuel gasoline until the vehicle manufacturers could certify it won't damage expensive assemblies/connections/parts. I won't be holding my breath, but then you never know. Ethanol is, of course, grain alcohol, and as more of this "green" product is used for motor fuel we're seeing/hearing anecdotal reports of damage done to fuel systems in some vehicles, others unable to run it because the combustion programming won't adjust for it. Just my two-cents worth. You're free to try your luck.
