[Hypermiler1995]

I have used acetone in my 90 corolla, but it seems to only lower mpg, then the mpg stays down until the fuel filter is changed. I think this is because it cleans the fuel system very aggressively, which causes the gunk to clog the fuel filter; I use it as a fuel system cleaner, 2oz per tank for 3 tanks, none in next tank, then change fuel filter.
