Trans/ rear diff you can run John Deere rated Hydraulic oil, the front diff needs strait 30 weight oil. 1 quart of Dexron ATF works just perfect for that. Motor oil is where people make a mistake. Do not run a generic mobil or other automotive oil in your engine. I personally run Amsoil powersports 0w-40 and their wix filter and each oil change costs me near $24. I would say go this route or run the polaris motor oil. There is no reason to run the $12 polaris filter. I've been running thousands of hours without the polaris filter (on 3 machines) and actually am having less engine problems now then I was before.
If your machine is under warranty, you may want to consider running their oils. You don't want to give a dealer a reason to deny your claim.
