There is tons of information on this available with a quick google search. If done, it would reveal that this person is not looking to use acetone to clean anything or as a gas substitute, but to improve performance and fuel economy. There has been a lot of tests done on this, although not many high profile. The science of it is generally that the acetone in small amounts (2-3oz/gal) reduces the surface tension of gasoline allowing it to burn more thoroughly thuhs wasting less gas and improving performance. (Gas normally does not burn very efficiently). There have been a lot of mixed results, but as long as people stick within the recommended parameters of useage (2_3oz/10gal) I have seen nothing indicating any problems. I just recently tried this and am noticing improved mileage. I will start logging mileage after I finish this first tank. There was a study done with 4 diff cars and each showed significant performance increase when using the recommended amount of acetone. (With diminishing results when more was used) the goal is not to dilute the gasoline with acetone, but to use just enough that you reduce the surface tension.
