Diff oil advice (1 Viewer)

Hi All, I had tjm pro locker installed in front and it's time for first change. Shop recommended 85w-140. Live in Dubai so it's is crazy hot year round. Question is, any reason to not use the same in rear diff with factory e-locker? If not I'll just get jug of each. Best diff oil for rear in this climate?

I would use full synthetic 85w-140 in both diff’s and transfer case.
I’m a fan of Castrol, but you can use whatever you want.

Electronic/Air/Mechanical I only LS (limited slip) rated diff/gear oil.
