Sounds like old racer tricks to spike fuel for a competitive advantage. -- Mike -------------- Original message from "twinenginedmc12" <rhg@xxxxxxxxxxxxxxxxxxxxxxxx>: -------------- I have experimented with acetone and toluene as an additive. Found both to make the engine run smoother, and both to dissolve contaminants, and subsequently redeposit them in the carburetor. Had to disassemble it to render it functional again. After the toluene experiment, I had to reline the tank. Abandoned it. The addition of "a small, but precise amount" of anything in fuel to improve MPG, or emissions, or burnability, or any other parameter, is a suspect concept from the start. If there's a cheap way to get more performance out of the fuel from additives, you can bet the fuel companies have done it already. There is little room for improvement by the general public. I saw your earlier claims about fuel economy, and view them with grave skepticism. I believe you are either deluded, or dishonest. Acetone is quite toxic. It should be handled with care.
