I'm gonna be changing my Dif oil and gearbox oil soon and just wondered what everyone elso uses?

I was gonna use Castrol SMX-S (75w-85) for the Gearbox
and Castrol SAF-XJ(75w-140) for the Dif

The local dealers recommendation was Castrol SAF-XO (75w-90) for the dif

Would the XO(75w-90) be better than the XJ(75w-140)?

This is what Alpina reccommends, I would go with that. SAF-XJ is available from BMW, SMX-S is available from aftermarket sources (in Europe and England), but not in USA or Canada.
