the whole acetone thing was tested heavily on another forum I post on about a year ago, and nearly everyone that tried it showed huge gains in gas mileage. The concept behind it is that the acetone helps to atomize the fuel better... works similar in concept to how soap works.


I've also seen tests done on engine components to test any damage that acetone would do to hoses/seals, etc in the quantities suggest here, and it has been shown to do no damage.


I realize the snopes link suggests otherwise, but actually knowing people that have tested it themselves and taken very accurate measurements, I find it at least worth a try.
