Is it ok to use Royal Purple 85w-140 automotive gear oil with limited slip additive in the chaincase?

Should be OK, not 100% sure about the additive tho.

I'll move this to the can-am area, it'll get more views.

I ened up using mobil 1 synthetic 75w-90 in my gear box, and my differentials. The recomended oil made by castrol for BRP is basically a synthetic 75w-90 weight gear oil. So if you can find some castrol syntec 75w-90 synthetic gear oil that is the same stuff they sell thru BRP. But is costs $22 a pint. The RP you are suggesting seems a little to thick, plus the additive is not needed.

Thanks. I switched to Mobil 1 75w-140 synthetic for the gearbox, and 75w-90 for both front and rear diffs.

I think you'll find the oil in the diffs is clean. The oil from the gear box was very dirty.
