My 2000 polaris magnum 500, not sure what hours on the oil, maybe 20 or 30..... Put in last fall, was some 5w30 PYB and a little bit of Motomaster 5w50 and Fram ultra filter.
I kept the filter as the hours were not bad. In went Conventional 10w30, Co-op DMO CK4.
She is all greased up and tossed in a new fuel filter. Ready to drag the arena for the summer.
