I'm pretty sure:
The following is the only recommended and approved synthetic oil for BMW M (Motorsport) vehicles in the US market with gasloline engines, at the present time.
BMW Long-life rating LL-01 Synthetic Oils for BMW M Vehicles equipped with S54, S62, S65 or S85 engines
BMW Long-life rating LL-01 Synthetic Oils, for BMW M Vehicles equipped with: S54, S62, S65 or S85 engines
But you can convince yourself whatever you want to believe.

equipped with S54, S62, S65 or S85 engines:
1) Castrol EDGE Professional TWS Motorsport SAE 10W-60 Synthetic Engine Oil, BMW part number 07 51 0 009 420
2) Castrol Edge Professional OE 5W30 Synthetic Engine Oil BMW part number 07 51 0 037 195
The first part tells you that only LL-01 oils may be used in the S65 engine, and the second part tells you that out of all the LL-01 oils, only the two enumerated oils are approved.
I'm pretty sure the EDGE TWS 10W60 is not an LL-01 approved oil -which would defeat the above interpretation.
It only says that they are "endorsed for use in BMW M-Model engines"
