Diff oil

[mxzguy]

Going through some old oil on my shelf and found an almost full bottle of Maxima 80W90 from the Polaris days my question is that this oil is an A.P.I GL-5 and my Grizzly manual states the diff oil should be A.P.I GL-4 does anyone know the difference and if this will work for my Grizzly

The difference between GL-4 and GL-5 explained

When you are choosing a transmission or gear oil you might be wondering what GL-4 and GL-5 mean and what the differences are between these two classifications. Choosing the right classification is extremely important since they both have different properties and wrongful use could lead to...

Gl5 doesn’t play well with yellow metal from what I understand.

What year is your grizzly?

so you are willing to damage your diff for a 7 dollar bottle of oil take it and throw it out

There are some dual rated gl oils out there, i bet lots of people just look at the 80w90 and dump it in. And even more do not have a clue about ma rated wet clutch oil for their engine and what damage that does.

Sounds like I won't use it the Yamaha stuff has GL-4 and GL-5 rating so I thought might not be much difference but didn't know so thought I would ask thanks for all the responses
