Acetone is about as mild a solvent as you can find. Try dissolving fingernail polish with gas and see what you get. Gas contains large amounts of toluene, which is used as a plastic solvent, and gas (particularly the high-test stuff with "detergent" additives) contains levels of extremely powerful solvents to help remove built up varnish and carbon deposits on engines.
The stuff in gas is far worse than acetone, and the fuel system has to be designed to handle it. Pull an MSDS and query some of the compounds to see what I'm talking about -- high test gas is up to 50% "gas" hydrocarbons (C3-C12), as well as toluene and xylene (up to nearly 50%, but maybe much lower depending on the blend) to boost octane.
Then there are trace amounts (under 1% each) of 1,2,4-trimethyl benzene, styrene, benzene, ethyl benzene, hexane, cyclohexane, napthalene, MTBE, ETBE, TAME, and DIPE. Even from the same brand, the amount of the above compounds in gas from the pump can differ wildly.
