Have a question, since I had my M Coupe the first time after the purchase at the oil change. There was then everywhere that one filled a 10W60 of MOBIL. Now my question, whether this is the right one? Here was written earlier about that only the Castrol TWS 10W60 was approved for the M engines, even the Castrol RS 10W60 did not have an “official” approval from BMW for the M ́s. Does anyone have experience there? I was especially at a BMW dealer also because of the Gara ntie (EuroPlus). Btw, have also the impression that he consumes more at the moment, but that can also deceive, because I drive a lot of short distance. With thanks for a good advice, from Basel greets everyone, Reinhard
