The following info was obtained from BMW(GB) after my dealer put the wrong oil in my '99 M5.Castrol RS spec is no longer BMW approved Castrol are marketing a new oil as RS and the BMW approved 10W-60 and 5W-40 have been given new titles of castrol TWS(10W-60) and SLX (5W-40).
Not sure how this effects the US owners.
The BMW(GB)technical sheet number is GB-00-001-01 issued 23/3/01.
