My latest service is just complete. So far I have went a little over 8K miles for each of my two years of ownership, and at 12 month intervals, have had the oil changed.

This time the dealer did not use the TWS oil and instead used the 5W-30 oil part number 07-51-0-017-954. So now I have had both types of oil in the car. It is the first thing I looked at on the invoice, and I had the TWS oil part number with me, so I knew it right away. I remembered all these posts, and was in a hurry to leave, so off I went. If I happen to now get slightly better mileage, I will assume it is due to the different oil.

Does anyone still recall having the dealer use the TWS oil in the X6M lately? Maybe their service instructions have now been updated to inform them that it is not required?
