Fog the Engine
-
Treat the fuel system with POLARIS Carbon Clean or other equivalent fuel treatment. Follow the instructions on the container. Start the engine. Allow it to idle for several minutes so the Carbon Clean reaches the injectors. Stop the engine.
-
Remove the spark plug and add 1–1.5 oz. (29.5–44 cc.) of engine oil. To access the plug hole, use a section of clear 6 mm (1/4”) hose and a small plastic squeeze bottle filled with the pre-measured amount of oil. Do this carefully! If you miss the plug holes, oil will drain from the spark plug cavities into the hole at the front of the cylinder head, and appear to be an oil leak.
-
Reinstall the spark plug. Torque to specification.
-
Apply dielectric grease to the inside of the spark plug cap. Do not reinstall the cap onto the plug at this step.
-
Turn the engine over several times. Oil will be forced in and around the piston rings and ring lands, coating the cylinder with a protective film of fresh oil.
-
Reinstall the spark plug cap.
-
If POLARIS fuel system additive is not used, fuel tank, fuel lines, and injectors should be completely drained of gasoline.
