Blackstone Comments:
The engine liked the Mobil 1 just fine. In fact, almost all of the wear metals are little lower this time, though the shorter oil
run probably didn't hurt in that regard. We don't generally see much difference in wear between the various types of oil,
so either the Mobil 1 or BMW brand oil should work fine. Or try something else if you're curious. There's no fuel this time
around and the viscosity is in the correct range for 0W/40. Air and oil filtration are excellent. The TBN is 4.6, showing
active additive left. Try 9,000 miles on the oil again.
