I am an opportunist when buying oil, which means favoritism gets back burnered. Now in my cars, boats and bikes I am running Pentosin, LubroMoly, Elf, Motul, Delvac, Chevron, BRP (Castrol), Drag Specialties.
I suppose if it could find deal on Motul 300V I'd run it in everything. Race oil that can handle heat and has a streetable TBN. And it's fluorescent green!
