If you can get your hands on some Valvoline SuperSynth 5W-40, which is BMW LL-01 approved, get it! In my previous car (VW), I did somewhat extensive oil testing over period of 4 years and 9 oil changes. Mobil1 0W-40 was performing very poorly.
The Valvoline 5W-40 had the highest TBN number of any motor oil that I've seen being approved for our cars.
BTW, the VW approved oils are also get the BMW LL-01 approval stamp also.
Equal Opportunity Harasser!
