I realized, after handling scores of these 'what oil' threads, that if someone actually asks what oil, they 'probably' (based on anecdotal evidence) want you to give them the BMW-approved list.

The second group never asks, other than to doublecheck their comprehensive calculations.

And the third group can read the 'quality' on the can so they don't ask either.

Yes. He's pragmatic. Logical. And sane.

That's logical for the third group of people in this group; yet it's anathema to the other two!
a) Use only bmw-approved oils (based on LL standards)
b) Use only bmw-approved & similar oils (based on LL standards and specs)
c) Use only bmw-approved & similar oils & any other 'good' quality oil (based on LL standards and specs and other well-established standards)
