zfdoc says Castrol TWS 10w-60 full synthetic. It can be bought at the local BMW dealer only & it comes in Liters only. You need 2.2 liters to do the change.

I bought it from this guy the last time as the local BMW dealer is not easy for me to get to.

btw, it's motor oil for an M5.

The rear gear I used Mobil 75w-90 full synthetic plus one bottle of GM posi additive. If you use GM gear oil then use two bottles of posi fluid additive. Or you can use Amsoil sever duty fluid plus one of their posi additive bottles
