| Some say acetone works. I have read between 5 and 10% increase, but I haven't tried it myself. I think the fomula is somewhere between 3 and 2 oz per 10 gallons of fuel. Acetone is the base ingreedient in a lot of paint thinners(can be bought at most hardware stores in 100%). Be sure to do your research though.... some say it is hard on the seals in your engine. |
