According to the forum and BMW, Castrol TWS 10W60 and Castrol Edge 10W60 (not Edge Sport) are approved for our M vehicles.
I have been worried as I can only get Edge Sport and not Edge or TWS around here, and I am concerned Edge Sport might not be the right oil for my car. Any ideas if composition-wise or film strength, Edge Sport is different than TWS or Edge?
Thanks very much!
