An ARB air locker is not fussy. As long as you use a good quality diff oil they will work just fine. They are only an open diff unless locked so an LSD oil will give no benifits.

Yeah, from what I understand, with the new viton seals, LSD oil is no longer a problem. I heard that the earlier ones had problems with the o-rings, but the new seals seem to be ok

Every ARB i have ever worked on had Viton seals so i cant see that being an issue. Pinion seals and axle seals are generally not Viton either and they have no issues with LSD oil.
