I use lucas full synthetic gearcase oil 75-90wt in my rear diff and transfer and gearcase .... the front i use john deere low viscosity hyguard transmission and hydrolic oil yep the front diff need that special oil i dont use any polaris oil products as amatter a fact i use honda gn4 10w40 in my engine i swear by it too....

 

i swear by Polaris oil ....... i used mobil1 in the motor before the rebuild and it will mix with the polaris oil also if your oils DIRTY there is still like a 1/3 quart still in there , i use the mobile 1 to flush out the motor ! I take 2 quarts, dump them in with the drain pulg out making sure it is going in to a clean pan so u can reuse it run it thru a couple a times and your dirty oil will simply go away ! then refill with good oil and your oil will stay cleaner longer ! also i use the fram filter i dont re 7313 i think ..change oil often , and your motor will love you . also do the front end a lot more too there is only a little oil in there

 

used amsoil atf in front diff, 75/90 sever gear in rear diff. 5/50 in engine, hot down here, 2000 chain case for trans case and transmission all synthetic, oh yeah, there is a sticky for this

 

I use the Polaris Fluids in my XP...

 

In the rear diff I was using the Polaris gear lube but now I have Redline 75-90 in it. The front diff I only use the polaris stuff, hub fluid or whatever it is called. Transfer case and Tranny I use the Polaris AGL (the purple stuff).

In the motor I have been running Amsoil 4Stroke 0-40.

 

Polaris fluids for all lube needs.

i have searched my eyes screwy on this as well.......well today i'm getting my 5gal bucket of Mobil 424 hydraulic fluid.

i'll be using mobile 424 in the front diff and trans/transfer

the bucket is free so how can i turn it down....

 

Chris, what weight of the Redline oil do you use? I used HW in my Hewland sequential transaxle gearboxes in formula cars. The boxes ran at a much higher temp than I would expect in a RZR. The techs at Taylor (who would blueprint our boxes) saw much improved pressure angle wear and less pitting on the gear face when used over other products. I would like to use it in my RZR but was hoping for a guinea pig first!:rofl3:

The shock prof heavy gear oil isnt really rated ... they say it like having 75w250 ... works well both cold ...and really good hot. It pours like thick strawberry milk .... not like you would think with that rating!

 

Amsoil ATF in the front diff and Amsoil 75w90 Marine gear oil in the rear

 

Chris, that answers my question. I have used Heavy in higher HP cars and the "blue green soup" Medium in 190hp and under cars. The heavy has a very high film thickness even when at operating temp. but it takes a while to get there. I would be worried about good circulation while still under operating temps. I don't tend to do a proper warm-up with the RZR like I do on race cars. But...obviously the Heavy wt is working for you. On a side note, I have run a 15min. qualifying session in my formula mazda with a gearbox that was not refilled by the mechanic after a gear change. I had Heavy wt Redline in the box and since we only changed a section of the gear stack and did not do a full inspection (requiring varsol cleaning of the components) the residual oil in the box allowed me to complete the session without damage to the bearings or other internals except some pitting on 2nd and 3rd gear pairs which were the most highly stressed ones at that track. If it were not for the "clinging" properties of the Redline I would have been looking at a 8-12 K rebuild on my gearbox. The Redline is a fantastic product.
