gear oil...

I run Lucas in all my stuff. 80/90. Seems to work just fine.

There are those that would argue that "oil is oil" and as long as you change it regularly, you won't have any problems.

this site has lots of good info.

For a four wheeler/ not highway driven cheaper is better. In general our gear boxes don't get hot enough to need the fancy stuff.
 
I just run 80-90w in the diffs--like rick says the diffs don't get that hot if its a wheeler. But I do run redline synthetic in the gear boxes.
