My rzr 900XP calls for PS4 2w-50 (-20 to 100deg) but the PS4 Extreme is 10w-50 for temps range of 0-120 deg and Also recommended.
Polaris would tell you beware of the higher RPMs these machines turn and the lack of corrosion inhibitors in automotive oil.
Im sticking with the Polaris PS4 on my DOHC 900XP for now.
But…
I’ve used Mobile 1 in the past on my quads but may switch to Quicksilver ATV 5w- 40 for the above mentioned reasons.
Any experience with Quicksilver? Is it a high quality oil?
I’ve done a little research but what do you all think?
Thanks.
Jim
