People post from time to time what are the best fluids to use in our machines. Some people reply that you need to use the Polaris fluid for the front diff and tranny because if you don’t it causes the front diff not to engage right and the motor oil will not protect the internals of the tranny. The myth that you have to use these certain fluids is just what it is and that is a myth. The Polaris tranny has not changed much at all over the years and for years plain old dino oil was the Polaris fluid of choice. The front diff has changed with the addition of ADC and moving the hubs all to one piece in the diff. Polaris seems to change their fluids more than a woman changes her hair and who knows for what reason they do it. I think they do it just to try and get the public to believe that their fluids are the only thing that will work or your machine will not operate properly. I have put all these miles on my machines from Moab, Hatfield McCoy to the Paiute Trail and not one single problem from running these fluids. Here is my fluid of choice for my 2006 X2, 2009 XP and my 2014 570. I am not telling anybody to run these fluids I am just pointing out that these fluids have worked like a charm in the tons of miles I have put on my machines.

Motor-Mobile 1 0W40 my fluid of choice. I have ran Castrol 0W40 or 5W50 when Wal Mart is out of 0W40. I have Royal Purple 5W40 in the 570 now just to try something different.

Tranny-5W20 motor oil of any brand

Front diff-Mobile 1 Synthetic ATF

Rear diff on XP-any brand of gear oil 75W90

Anti freeze-any brand of 50/50 pre mix

I stick to the good brands when it comes to the motor and front diff but when it comes to the other usually I get what is on sale.
