I had some down time the other day and found myself perusing the go to oil forum on the net. Don't know why, but ended up in the fuel additive section. So there's this guy that is racking up miles using 2 cycle mixing oil in his gas burners fuel tank. He's done many thousands of miles and has actually taken apart a perfectly healthy engine to prove his results. It seems that there is a newer designation for marine mixing oil called "tc-w3" that when used in a conventional four cycle engine, added to the fuel, will remove carbon, clean up ring packs, lubricate the upper cylinders, improve mpg, and safe for catalytic converters. I've run one tank of this through my commuter car and already seen the mpg improve about 5%. Real results are not supposed to be seen until you've run 3 tanks of fuel through. The recommended mix ratio is one ounce per 5 gallons. If I continue to see positive results, I'm going to do this to the bike as well....
I wouldn't care on the bike, but my cage gets an average of 28 mpg. First tank of mixed fuel netted me 29.6 mpg. There are over 50 pages of discussion on a gto forum that not only explains how and why it works, but includes user submitted data and results as well.
