My M5 has not burnt a drop of oil since 2000K's. I used Castrol 0W-40 to top up when it burnt oil for first 2000. (Approx 3Lt.) I also open Bonnet at end of every drive to help cool engine quicker. Don't know if this is reason for no oil burning, it's worked for me. My car has done 8000K's. Since it stopped burning oil have noticed no black on my exhaust tips to clean. Good luck.
