Correct oil, being the Castrol Synthetic 5w-30? Do you really think there is a difference between that and Mobil 1. From what I have read, Mobil 1 is better in all aspects than the Castrol of the same value. Just asking because the consensus on this forum is that Mobil 1 over Castrol is the way to go.

Regardless, your oil consumption is within BMW's specs.
