I have been looking into swapping oils. I recently had BMW do a oil consumption test and it is with spec but goes through about a later every 1300km. It's crazy.
I noticed most everyone goes to a thicker oil 5w-40 and 5w50 etc, I was looking at Castrol Edge website and noticed they do an oil that is 10w-60 which seems way to think but it does say that it is suitable for all BMW M-Models.
Has anyone tried this?
