Well, I think people are too busy second-guessing BMW. My last two BMWs (750,645) both had their oil changed strictly on CBS which was typically around 25,000 kms. Both cars are problem free and heading to 200,000 kms each.
My current GC shows an oil change due at 24,000 kms and that's what I'll do. It's presently just short of 10,000 kms (6,000 miles) and has used no oil at all.
Incidentally, the oil is Castrol Synthetic 5W30.
Cheers,
Bill
