None. I would stick with the dealer's offer just as I do. By the way, last time they put 5w30 instead of that ///M 0w40 they had used previously. When I asked WTF they noticed my engine wasn't a M-Performance one and failed to explain why they had sold me that "excessive" oil before then, yet acknowledging that the ///M oil was available had I told them I wanted it.
