I bought a quart of PS-4 oil from the dealer when I got the machine in case I needed to top it off. They said that’s what goes in it
My friend just sold his RZR 900 and gave me a gallon of PS-4 Plus oil
Can I use that in the 1000?
Not sure the difference between the the PS-4 and PS-4 Plus
Here’s a picture of the the quart the dealer sold me and the gallon my buddy gave me
What do you think?
