Hey, just lookin for some insight and too lazy to search the forums.. Should I be OK with Synth 80w90 for both diffs on my 06 Foreman 500? Gonna drain and fill this week, after 700 Kms.. Any tips?

Thanks folks

I run 75W90 synthetic in mine with no issues so 80W90 will be fine.
should be thats what i used
I'm also running Synthetic 75W90,no problems.Around here I've only seen Synthetic gear lube in 75W90 and 75W140.
So should a bottle do both diffs?
