I have always used Mahle filters before too. On my Porsche 944 Turbo and on my e36 323i Never had a problem either. Thats why I was kind of surprised to see a differnce in filter designs bewteen the OE and OEM filters. Maybe I am being to OCD. lol

As for your original Q, on what oil BMW uses as a factory fill. It is Castrol. It says that on our engine oil caps! "BMW Recomends Castrol Synthetic oil". I think its probably Castrol RS Edge full synthetic - but I am not 100% sure on that. I just know BMW dealer sell the Castrol oil for our cars at the dealers. In the states and over here in Germany. I will have to look at my aftermarket suplier for which Castrol Oils comply with BMW LL1 rating.
