BMW M3 Forum (E90 E92) - View Single Post - What type of oil to put in my 2011 m3 e90

I've read in other threads that the 10W-60 TWS breaks down pretty quickly to about 10W-50 viscosity and stays there for the full life of the oil (15k miles). The 50 weight is necessary for the very high temperatures this engine generates when driven hard (as in at the track). If not tracking the car, I believe something like Redline 10W-40 would be more appropriate. I'd mix it 50/50 with their 30 weight race oil and change it at 7500 mile intervals.

By the way, on the TDI forums, more and more oil analyses are supporting 20+k mile intervals. And that's with a diesel!!!!! I'll stick to my 7500 mile intervals, but food for thought.
