I'm changing the fluids in my transmission, as well as front and rear gear cases. My manual says to use "Premium Synthetic Gear Case Lube" in both the transmission and rear gear cases. It instructs me to use "Premium Drive Hub Fluid" in the front gear case.

I stopped by the Polaris dealer today to pick up Polaris fluids, and they told me to use:

1. AGL Plus Gearcase Lube in the Transmission
2. Demand Drive Plus in the front gear case
3. ATV Angle Drive Fluid in the rear gear case

I showed them my manual and question the Angle Drive in the rear, and they advised me not to use the AGL Plus in the rear.

Opinions?

 

They are correct. The AGL is for the transmission, and the newer quads that have the rear gears in the transmission housing. The angle drive fluid is correct if you have a separate rear gear case from your transmission.

 

I use synthetic 80-90 in the rear diff,Demand drive plus in the front diff, Castrol syntec 5w-30 in the engine and tranny, the engine on the 600 takes a 51357 wix oil filter, I service a number of machines for other people as well as my own and find the Castrol has worked very well for alot of years and miles, I use these flouids in my 850 too,
