As long as it's the same "weight" then any of the larger brand name manufacturers will be fine.

as in weight do you mean castrol is 80/140 is the right oil as long as its the same as that it should be ok?

I think Castrol LSX90 is the common pick ? check your workshop manual or owners handbook ... or even one of those lube selector websites like valvoline or castrol both have.
From memory the oil should be GL5 ? and suitble for hypoid gears for a VS diff. Don't quote me, i just memorised what was on the old bottle lol.
