I run it in my Scout and it helps the mileage plus it starts and runs like an injected engine. The Scout is a gasser with a carbureator. The benefit of the acetone is reducing the surface tension an allowing for better atomization of the fuel, hence a more efficient burn. Not that much help with an injectected engine that sprays the fuel in the cylinder. The old Scout warms up about like an old Harley, but with the acetone it cranks and drives off like it had fuel injection plus an increase in mileage.
