What would recommend for a B36/B38 Engine for auto crossing and on east coast, so climate from 0*F - 105*F?Mobil1 dropped all BMW LL approvals. Reason is updated in 2018 (Mobil1 dropped earlier in 0W40 FS as they knew what update will be).
IMO, Mobil1 has higher oxidation than other oils (they do have esters in oil) and BMW made oxidation requirements in new update ridiculously high.
I would use it in 320d. But not in N16/20/26 as new update has specific timing chain test designed around those engines.
What would you reco without auto cross?
Thanks!
