I just bought a brand new 2008 Polaris Outlaw 450 MXR. I was going through the manual and it recommends the use of Polaris PS-4 Plus Performance Synthetic 2W-50 4-cycle oil. It also states do not use Polaris PS-4 Performance Synthetic 10W-40 Oil. Always use 2W-50.

I usually buy most my stuff on Motosport.com. When I put in my bike and then run a search for engine oil, it mostly comes up with 10W-40 and 20W-50.

Is 2W-50 a typo? What oils can I use on my bike?

Thanks,

Joe

 

Nope, not a typo. The Polaris oil is 2w50. However, the consensus here seems to be that any good 0w40 synthetic gets the job done. That's what I use in my Scrambler.

 

0w-40 Mobil 1 or any other manufacturer if available, OR PS4 Plus 2w50. Other listings on oil on the internet can be deceiving,or just flat wrong. Although this may start another "oil war" as some people will still use their preferred brand and "weight". It is in fact a KTM engine and in some of the race bikes guys use Motul 5w30,5w40 or 10w40 Gets a little complicated when "two" manufacturers are involved. I would go by the manual and keep all oil receipts in case of any engine problems. This is just to CYA! OPT

 

2-50 is what most the new polaris bike have in them stock as it used to be 0-40. makes sense to at least staying w/ the 0-40 if you can't find the 2w-50 full syn. oil.

 

Thank you!

 

Cant see how you can go wrong with 0w-40 it cover the coldest temperatures to the hotest.

I think the odd ball 2w-50 weight is so people buy Polaris oil only and not the aftermarket brand of there choice.
