unknown oil, 2010 BMW N54 engine, unknown mileage

[cchase]

Ran this oil analysis for our 2010 BMW 535xi. This vehicle was purchased used as a CPO with ~20,000 miles. The dealer claimed the oil was changed at about 18,000 miles as part of their inspection/rejuvenation but I'm not sure I'm convinced.

Any ideas what oil this is? The easy guesses I could think of such as Mobil 1 0w40 and BMW 5w30 don't look like this to me.

To me, it does look very much like BMW 5w30...

As for your UOA, iron looks a bit high, but maybe the engine is still breaking in?

I agree with QP, probably the BMW/Castrol 5w30.

Okay, that looks more similar. The VOA I found for the BMW 5w30 had different values for moly and zinc.
