I put aceton in last week. 3 oz to 15 gallons. It's still got a half tank so I can't check the mileage yet. It's a 4.3L auto CPI injected. Stock truck accept the 2/3 lower and edelbrock headers. I checked the mileage last tank with cheap arco regular. I got 15 even. (in town only driving in this truck) Anyone care to make a prediction on this tank with the acetone? My guess is
15 tops.....- posted
