For standard diff, Castrol LSX 90 or equivalent.
For LSD or Supercharged, Castrol SAF-XA or equivalent.

I'd be a little hesitant to use SAF-XA. The added friction modifier tends to make LSD's very unpredictable.

im pretty sure its a single spinner so ill head down to super cheap or similar when i get a chance too
