Does anyone know what the best alcohol is for burning in a gas engine? I'm thinking about putting in this "mist" thing that's supposed to boost mileage and clean the motor by running damp cool air through the motor. I don't know what alcohol to use in the mix, though. Anybody have any thoughts on it? I was just cleaning out my desk and found the plans for it that I printed from the 'net a couple months ago. Ratch CK5 album Prior signature burnt. This one on temporarily.
