Ive been using rotella t6 year round including track days for the past few years. Motor is still pumping. Rotella is marketed as diesel oil but it also has an SM rating for gasoline engines, which covers 2010 and older engines. I like it, never got a Blackstone report though. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM |
