I was planning to do my first DIY oil change, and I bought the BMW SAE 5W-30 High Performance Full Synthetic Motor Oil. As I checked the back of the bottle of the oil, it says "Meets all requirements of ACEA A3...blah blah blah". However, as I remember from my E92 owner manual, BMW prefers "BMW Longlife-01", and ACEA A3 is just alternative. Even Tischer sells BMW SAE 5W-30 High Performance Full Synthetic Motor Oil, so I'm thinking this might be the engine oil originally come with the car when it is built in Germany. Does anyone know what kind of engine oil is inside our E92 engine when it is built in Germany? How well do BMW SAE 5W-30 High Performance Full Synthetic Motor Oil serve the N54 engine?
