Diff and Final fluid for ATV Grizzly 700

[BobsArmory]

My 2012 Yamaha Grizzly 700 ATV calls for an SAE 80 API GL-4 Hypoid Gear oil for the Differentials and Final.

Since I will change it rarely and it uses so little I am not overly concerned with cost.

Do you all have any preferences on which product to use?

Also, any problems going with a 75W-90 instead of SAE 80?

I use 80w90 hypoid gear oil in the rear-end of my quad. No problems and an 80w is recomended in mine as well. I've had very good with the suzuki brand oil,bought that because it was on sale. I've heard very good things about amsoil though. Id use that if I where you. But gear oil is gear oil in my opinion. Used many brands and they all seem about the same to me

Amsoil 80w90 in mine since break in.
