Looks like Castrol changed formulas. Traditional 0w-40 A3/B3 where LL01 spec'ed but it is no longer. However 5w-40 US is.

Any thoughts on using this for n20/n26 engines?

Walmart. $24.00. Castrol's 0W-40 is a much better product. If it weren't available, M1's 0W-40 (IMHO, of course) is the next best choice.

It's $27 for a 5-qt. jug in my area, and we have a nasty 9.45% sales tax too. Mobil 1 is about the same.

If your car is under warranty, use non-spec oil at your own risk.

I am not questioning the properties of the oil whatsoever. Just pointing out if there is a warranty issue, BMW will want to avoid paying by any means possible.

Ahh a different view. It all makes sense now. Sad. Haha
