Has anyone heard of adding Acetone to your gas to get improved power and mileage? Here are a few links: http://pesn.com/2005/03/17/6900069_Acetone/ http://peswiki.com/energy/Directory:Acetone_as_a_Fuel_Additive I am trying it in my 2001 Taurus. It seems to improve power a little. I will find out about mileage in a week. I can't help but wonder if it would improve the carburation of a 650R with the stock carb? I also wonder if it would attack the plastic gas tank. It would be about 1/2 an ounce of acetone to a tank of gas, so would be very diluted. Anyone want to talk me out of trying this?
