Mileage
You can probably maximize mileage better than using additives by keeping tires properly inflated and perhaps a pound over would be better. Also, coasting out of gear as much as possible, accelerating from stops as easily as possible, and "timing" signals so that you don't have to slow down or stop as much. On the highway, maintain as steady a speed as possible, keeping it at 55mph if you can. I try to keep my engine RPMs steady and just at the low end for that gear without lugging the motor. The other trick is to do it so as not to piss off the drivers behind you. Maximizing mileage is sort of a game with me. I typically calculate mileage between tanks of gas. I find that the biggest problem is other drivers bad habits which cause you to have to accelerate or brake. Of course the Mazda Speed3 is not the most economical fuel efficient machine around to begin with is it?
As far as using acetone...don't do it. It loves to eat paint, rubber, fuel lines and seals and other stuff on your car. Did you know that top fuel dragsters have to wash out their engines in between runs due to using the nitro methane (similar in some ways to acetone in that it eats and corrodes engine parts)?
