Engine oil: 0W-40 Mobil 1 full syn engine oil
Transmission: 5W-30 Mobil 1 full syn (you can use many different things in the tranny, its just a some gears, chains, and bearings) chaincase oil, dex 3 or 6, GL5, or engine oil
Coolant: any conventional green coolant works mixed 50/50
Brakes: Dot 4 brake fluid, valvoline
Rear final drive: Valvoline GL5 75W-90 syn
Front final drive: if its a hillard drive (mostly 2004 and newer polaris models) then I use polaris demand drive, if it has hillards on the hubs (2004 and older polaris models) the I use GL5, some people use ATF type F or ATF dex6 but I find I do not use much of the fluid so I just buy the polaris stuff.
