That's what I thought. M-line vehicle(Engine model start with "S" instead of "N") suppose to use the Castrol TWS 10w-60. On page 243 of the owner's manual, it only says that the 3.5i and the 5.0i use 5w-30. The X5M/X6M comes with the supplemental manual but it never mention what type of engine oil it use. I call the dealer and got different answer as well.
