nothing a spill and fill (or 2 if needed) wont take care of if my a91 starts burning oil....so far 3 guys on the a91 edition FB page have had engine replacements running the stock oilIf you don't care about the warranty the Rotella T6 is fine. However if anything does goes wrong, you'll be stuck with the bill as it's not a BMW approved oil spec. I'm not disagreeing with you that T6 is a good oil btw, but BMW will never approve any warranty work if they take oil samples.
