BMW only spec'ed 10W60 oil for M cars because a bad batch of rod bearings was causing M3's to blow up (not the car itself, just the S54 motor). Prior to that, BMW Castrol 5W30 was spec'ed for E46 M3s and M5s.
I'll send my oil sample to Blackstone for an analysis, if everything checks out okay, I'm gonna try GC 0W30 next.
