acetone

[uberfast]

My dad told me he was reading up on fuel-saving tips and tricks and one of them he came across said to add 3 oz of acetone to an almost empty tank and then fill the rest of the tank with regular pump gas (as a fuel additive). He was wondering what kind of effects it would have on naturally aspirated or forced induction engines (as far as the actual improvement in the fuel efficiency and performance). I was curious about acetone injection.
