using Acetone in my 420 SEL gas tank...............
Fwiw, I just started using 2-3 oz. of Acetone for every 10 gal.gas in my 87' 420 SEL and I noticed right away that the engine was quieter, smoother running idle, seems to have more pick up, and the there is NO odor from the tailpipe. I know, it's sounds weird, but it is working. I will know more about any mileage increase in a few more tankfulls. These url's below explain what is going on. The Yahoo group is doing testing. If you do a Yahoo search for "Acetone in fuel" you will see a lot forums and interest in it.
