Research is one of my hobbies. I spent at least 20 hrs working on this, and could not find one shred of definitive proof it actually works. I think the most likely explanation for acetone having any positive effect on fuel economy is that it may do some cleaning of the fuel system. Mythbusters tested it on gas and it had no effect. Until someone can come up with some non anecdotal proof that it actually works, I think it's more fantasy than reality. Anecdotal miracle claims are worthless because no two drives are ever really the same.
