If you go by certification you would think that Casrol 5w-40 is superior when compared to Castro's 0w-30. However, Castrol's website shows that their 5w-40 is NOT for bmws that require LL01 ( see link, page 2) [ This LL01 cert must mean something. Why risk using royal purple or amsoil or any other oil without that LL-01 certification? Castorl 0W-30 and Mobil 1 0-40 have that certification. The complete list can be found on BMW's website
Yep the 5w-40 meets LL98.
