thetic 2W-50 4-cycle oil or a similar oil for this engine. Oil may need to
be changed more frequently if Polaris oil is not used. Always use 2W-50
oil. Follow the manufacturer's recommendations for ambient tempera-
ture operation. See page 100 for the part numbers of Polaris products.
NOTICE: Mixing brands or using a non-recommended oil may cause serious
engine damage. Always use the recommended oil. Never substitute
or mix oil brands.
