Nope, That's RTK. I'm not really partial to any one oil. Personally I use the Stihl, Belray H1R, Red Line, and Motul 800. All of them perform very well. The Pennzoil works just as well but for some reason everyone wants to run the stuff at 32 and 40-1. Makes a terrible mess at those ratios and doesn't perform any better than the others noted at higher ratios.
