Best oil for e9?

[taylorcom]

Does anyone have a preference as to the best oil (weight, brand) for the CS coupes?

I usualy run 20-50, but the owner handbook also recommends 30 and 20-40 in climates where temps are above 50F.

Personal preference is Castrol GTX 20W-50. In the US all BMWs came with it in early 70's.
