[Splurge]

I own a 2003 polaris sportsman 500 that I have spent way to much money on as it is.
So my questions are:

I need to do an oil change, what generic oil do I use
I need to change the transmission fluid, is any tranny fluid good?
I just changed the seals on my front hubs. What is the equivalent to awd on demand fluid?
I also need to go into my gear shifter box to change a spring...what goes in there?

Thank you to anyone that has answers for me.

motor oil-mobil 1 0w-40
front outer hubs-atf fluid- type F- if you want
shift box-i think they specify 5w-30, but whatever multigrade you got around the house works. just enough to cover the shafts.
