Attached is my first UOA on my new-to-me 2015 BMW M5 with 9,000 miles. The engine is a Turbo Valvetronic Direct Injection (TVDI,) twin scroll turbo 4.4L V8. The BMW dealer has apparently already performed three oil changes in the first 8,000 miles of the vehicle, so I think this vehicle has been very well maintained. I swapped out the oil soon after I took possession of the vehicle just so I could put in my preferred oil for my Central Texas climate, Ravenol VST 5w-40. The original fill in this vehicle from the factory was 5w-30 but BMW changed from Castrol to Shell and went to a 0w-30 "FE", or Fuel Efficiency. Since I believe BMW was more concerned with CAFE numbers than they were the protection of my motor with this decision, I decided against the 0w-30 viscosity. UOA looks very good with about 800 miles on this oil, which was the BMW 0w-30 which I believe is based of a GTL base stock.
