Just wondering what oil would you recomend to use with Powertrax Lock-Rite lockers?

I've read a few posts that people use limited slip oil for these however, looking at their website it says
"We recommend you change the differential oil according to your vehicle manufacturer's specifications".

According to this thread it seems that ARB lockers need to have limited slip oil?

Im asuming Castrol EPX80/90 be sufficient to use for diffs with Lockrite lockers or wouild something like Penrite LS90 be a better option as a few people suggested that it would be better to use limited slip diff oil with lockers?
Apart from the price difference between the oils are there any other advantages of using limited slip oil?

I've also rang Lockedup to see what they use and they suggested 80/140

Im assuming because the mechanical locker doesn't have any shims/packs i presume the "standard" diff oil would be fine?
I've also read a few posts where people say to use limited slip oil in even open diff centres

Thoughts or comments?

yeah mechanical locker are pretty happy with normal diff oil, i run some nulon additive in mine. helps it keep nice and quiet and drives a bit better/smoother. i run a lockrite in my rear.

Whatever diff oil you used before is fine.
