"True too much acetone hurts MPG the most gain would be at approx 4 oz per gallon of 89 octane or 2 oz per gallon of 92."


That's funny, Greg, because when I asked you what the optimum acetone/gasoline mixture back when I did my little experiment you told me 10%. That's what I did(give or take 1%). I have since seen the mythbusters episode where they exploded the myth. Guys, there ain't no mileage benefit to using acetone. PERIOD. -Bob
