Take a look at Castrol 5w-40 it states on the label that it is designed for bmws. It also meets all certifications for Castrol 0W-30. If you go by certification you would think that Castrol 5w-40 is the same as 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
If no codes are being thrown use Chevron Techron fuel injector cleaner (concentrate). It solves rpm fluctuating upon cold start-up. Also, for most BMW problems start off by scanning your car with the Peake Research Tool. It contains the actual BMW codes. If you want to register a newly installed battery for free (just buy a $10 cable) and google/download BMWLogger
