New report, this time with M1 0w-40, no filter change, winter. I'll try to get a report on the next one but it will probably be well below 5k miles as my last free oil change at dealer is due in July, may not be worth it.
Old thread for first report is HERE

BLACKSTONE COMMENT: No complaints here. It was a rough winter, but your BMW pulled through with flying colors.
Most metals have held steady or improved.
The only exception was iron, but an increase of 3 ppm is hardly anything to worry about.
It's still far below universal averages, so your engine is wearing much better than most of its kind.
There were no odd finds for the oil, physically -- no fuel, coolant, dirt, or moisture was detected.
The viscosity was good, and the TBN at 5.6 showed plenty of active additive left.
Try 7,500 miles next fill. Nice engine!
