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 first oil approved in the US for BMW's turbo N20 N54 N55 engines, including the S55 engine in the 2015+ F80 M3/F82 M4. This oil can also be used in E39 M5 and Z8 with the S62 engine, per the label inside the engine compartment. It can also be used in most MINI engines. Replaces the previous part number of 07510017866 (07-51-0-017-866).

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.

In January 2015 BMW changed official oil suppliers from Castrol to Shell. The new oils are designed to meet requirements of both the newer engines as well as older BMWs. This oil can be used in cars with either normally aspirated and or turbocharged engines.

Beginning with July 2015 production, new models came with 0W20 or 0W30 BMW oil. However, BMW dealerships continued to sell 5W30 until that stock was depleted. The 5W30 is an acceptable alternative to the 0W20 and 0W30 BMW oil per BMW's service bulletin.
