Diff oil for a NON XR6 Ute with and LSD

[_Ben]

Hey guys,

Done a heap of research but can't find a definitive answer.
I've got an AUII XLS Ute, with a 'High Performance LSD' diff (Thats what the tag says on it). What oil do I use it?

On Nulon and Penrites lube guides, they have an option for 'XR6' and 'Except XR6'. XR6 recommending 80w-140, non-XR6 recommending 80w-90.

I was under the impression it'd be the same diff, but with different ratios?
