04 yamaha bruin 350 diff oil

[Ohio91]

I have a 04 Yamaha bruin 350 and am looking to service the diff fluids. Bought it brand new and 04 and this would be the first time diff fluids have been changed. I don’t use it much except for in the winter plowing and the rest of the year it just gets moved around from building to building. What’s everyone using in these things as far as weight? I have some napa 80w90 in the shop already would that suffice?

I'd use what the manufacturer recommends way before I'd use someone's suggestion from the Internet. The owner's manual is online if you've lost it.

I did loose it I’ll look it up. Thanks for the reply.
