Funny observation.... ever since BMW started this included maintenance scheme, OCIs have nearly doubled. When you have as much cancer (Administrators and marketing) as most businesses tend to have these days, directives are often not in the best interest of customers, their interests are in cheaping out and shaving off every penny they see to pad their bonus check.
IMO your best bet to find the oil that best suites you is to determine how long you plan to keep the car and then to take an evidence-based approach. Routine UOAs will tell you what your favorite oil is doing for your engine, thats proof. BMWs new guidelines for a thinner oil are favoring emissions and fuel economy over engine longevity.
Just came off of the factory fill and went with Motul 8100 excess 5w40. I will do a 3k mile UOA on this and post results when it comes back. I drive the hell out of my M2c so the oil gets a work out!
