I found an old thread from 2000 where a few guys have had good luck with this stuff. I have been thoroughly impressed with the quality of the Red Line gear oils and bearing greases that I have used, and thought I'd give their fuel treatment a try. Does anyone know of a good supplier that sells by the gallon at a reasonable price? My local ditributor wants an arm and a leg, especially for something that's just going to get roasted out the tailpipe.
