Acetone is a perfectly good motor fuel ingredient, all other things being equal. Sir Harry Ricardo and colleagues used it in Castrol "R" motor racing fuel in the early 1920's, a mixture designed to have extreme heat of vapourization and charge density with high knock resistance. They used the acetone to get a soluble mixture incorporating benzene (I think) and water, plus ethanol if memory serves. See Ricardo's memoirs, "Memories and Machines."
What worries me is that acetone is a super solvent, and I suspect it would have drastic effects on any plastic parts (gaskets?) or rubber parts (o-rings?) in your fuel system. If they don't dissolve, they might swell. Also, the purported function of the acetone in this case (reducing unburned fuel) makes no engineering sense to me at all. In a gasoline engine in good condition and good tune, there should not be enough unburned fuel to be of more than negligible *thermodynamic* significance. The suggested mechanism by which the acetone is said to reduce unburned fuel dosn't make any sense to me. It does though have a certain family resemblance to "miracle carburetor" hype which I have encountered.
