I remember the MSDS's. Its just an UCL(oil) and FI cleaner(distillate). Probably no better then 2-stroke oil. And, Dipetane II had some biodiesel in it. Whoopie!
Make your own UCL, MPG improver, or cleaner.
I think that the price of dipetane is outrageous. Its $30 a gallon. 12 ounces per 20 gallons of fuel is pretty rich.
I'll stick with Lucas, Marvel, 2-stroke, or.....
