Just get the BMW oil.
Another option is Mobil 1 0W40, which is also LL01/ACEA3. But I burned oil with this vs not burning a drop I with the BMW oil in an N54 engine.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
