I know alot of people use Mobile One oil in their engines instead of the polaris brand. Is there any more acceptible substitutions for the rest of the fluids such as the transmission, front end, and the 4x4 hubs? Thanks.

 

There alot of substitutes for the manufacturer's brand. You can use typre-f transmission fluid in your hubs. I run amsoil motor oil for my counterbalance and their 2-stroke racing oil in my injected 400. From what I hear, a good synthetic gear lube at the proper weight ratio will work in the diffs. Hope this helps
