The BMW 5W30 motor oil is the factory engine oil approved for almost all BMW engines, except for BMW Diesel and some M3/M5/M6 engines. It's the only oil approved in the US for BMW's turbo N20 N54 N55 engines, including the S55 engine in the 2015+ F80 M3/F82 M4. It can also be used in most MINI engines.
This oil was especially formulated for the USA market to meet compatibility requirements with the high sulfer content in our fuels. It meets BMW LL01 and API SL specs for gasoline engines from 1997 up through today as well as ACEA A3/B3 requirements. This is the current oil used in BMW dealerships.
