Best oil for Tuned BMW M8 (S63TU4)

So what does BAS 5W40 give me that euro 5W40 (or Supercar 5W40...same oil) doesn't?
I think formulation is more geared toward higher oil temperatures over longer period of time. Probably more ZDDP. I mean, Motul 300V I used had like 1300ppm of Zinc and 1100 ppm of phosphorus. Not sure what is HTHS and KV100, I could never find PDS.
You would have to talk to Dave to see if he can share more details.
