Quote: I've only heard it touted as raising octane. I don't think there's much arguing that-it's pretty much proven fact as far as I know. I used it in the late 90's in a turbo buick I had. I stopped because it was kinda expensive.
At 1 oz per 10 gallons it'll do nothing for raising octane, maybe at 1 gallon per tankful though.
The only possible way acetone could improve mileage is if you had a dirty fuel system and it helped clean it out. I tried it in my daily driver and it did nothing. In fact other than the rather ill informed website posted and it's adherents there appears to be no reputable support for this idea. Hmm, that prior sentance implies the website and it's adherents are reputable, I did not imply that in case anyone is wondering.
