USE Synthetic ATV OIL, it comes in various weights. Valvoline makes it, but Lucus makes a good oil but it is 8 to 10 dollars a quart.
Polaris four stroke oil is a 0-40w synthetic.
You do not have to use so-called ATV oil. ATV oil is the very same oil as used in your automobile. Use any major brand SAE oil in the correct weight. I recommend you use a 100% synthetic oil.
0W-40. I use the AMZOIL ATV blend in mine.
PS-4 is the "Polaris" brand. Most people use 0-W40 as per most of the internet ATV forums out there.
0W-40. I use the AMZOIL blend made for ATV's in mine.
The type of transmission oil to use in your ATV depends on the model. Polaris uses their own transmission fluid. It is best to read the owners manual to determine what should be used.
There are many great Valvoline coupons that are available. I prefer to use Valvoline coupons that are related to getting oil changes.
you should use 10 w 40 valvoline depending on your usage you can use nomal or heavy duty
I use Honda 10w40 oil in our Polaris Sportsman 500. The only reason for the Honda oil is that I also own Honda motorcycles so I run the same oil in the bikes and the two quads. (We also have a Kawasaki ATV) Check the owner's manual for the specific grade of oil which should be used in your particular machine. The temperature range in which the machine is operated in is what determines the grade of oil to be used.
Valvoline
i suggest you use 10w-30 valvoline
