sorry if I didn't specify that clearly. but it's a good idea getting fluid like that

If your Bimmer is still under factory warranty why would you want to put something other than BMW approved fluids in critical and costly components like the transmission and differential, unless, of course, you know more about lubricants than the BMW engineers
Are you using something other than Castrol TWS Motorsport SAE 10W-60 Synthetic Engine Oil?
