I've wondered that myself. LL04 is a low SAPS oil which I run in my diesel. It's not necessarily better than LL01. LL01 is used in NA because the engines run richer, gas has over 15ppm sulphur, ethanol, and 13k mile oil change interval is required.
The dealerships pours Castrol SLX OE for my diesel instead of the BMW labeled juice.
