A recent issue of Auto Week had an article by Denise McCluggage that advocated the adding of small amounts of acetone to both gasoline and diesel fuel. A Google search reveals a number of very positive articles. Basically, they say, adding 2-3 ounces of good acetone to 10 gallons of fuel will give you about a 20% increase in mileage plus better emissions, etc. without danger to your rubber seals or engine. A good article is: http://www.pureenergysystems.com/news/2005/03/17/6900069_Acetone/

Surely one of my compadres out there has tried it and will comment. What say you?
