By the way, Castrol 10w-40: MEETS API SN, SM, SL, SJ, ACEA A3, B3, and B4 but why isn’t it LL-01 approved? This oil meets two other criteria API SN and SM more than 0w-30 and 5w-40 and it is not LL01 approved or LL-98 approved, why?
Perhaps it has something to do with VANOS & whether there is a market for it to be certified for LL01. The 0w-30 is the darling for Castro with its multiple approvals.
