Blackstone Oil Report
Mobil 1 0W-40
Make-up Oil Added: 4.5 qts inc. 3 qts Mobil 1 EP 10W-40
Comments from Blackstone:
Nothing too unusual showed up here. Most wear metals read a little higher than average, though this is to be expected with the longer than average oil run. Universal averages show typical wear from the BMW 5.0L after ~ 3,500 miles on the oil. All wear is still reading close enough to averages that we don't think any problems are developing. The oil was normal in viscosity and free of any harmful contaminants. The TBN was strong at 5.1, showing plenty of active additive left. 1.0 is too low. All in all, things look pretty good here. Try 12,000 miles on the next oil.
