MAINTENANCE Engine Oil Oil Recommendations Polaris recommends the use of Polaris PS-4 PLUS Performance Synthetic 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 temperature operation. See page 122 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. Oil Level Access the oil dipstick and fill tube from the left side of the ATV. 1. Position the vehicle on a level surface. 2. Lift the lever lock to remove the dipstick. Wipe it dry with a clean cloth. 3. Reinstall the dipstick completely, but do not lock it. The dipstick must be inserted completely to keep the angle and depth of the stick consistent. 4. Remove the dipstick and check the oil level. Maintain the oil level in the safe range. Do not overfill. Tip: Due to the dipstick entry angle into the crankcase, the oil level will read higher on the bottom side of the dipstick. Always read the level on the upper surface of the dipstick. Dipstick Safe Add Oil Safe Range 5. After reinstalling the dipstick, seat the lever lock. 72 { Check Level on Top Side
