Fog the Engine
1. Treat the fuel system with POLARIS Carbon Clean, following the
instructions on the container. Run the engine for several minutes so
the Carbon Clean reaches the injectors. Stop the engine.
2. Remove the spark plugs and add 2-3 tablespoons of engine oil. To
access the plug holes, use a section of clear 1/4" hose and a small
plastic squeeze bottle filled with the pre-measured amount of oil.
3. Reinstall the spark plugs. Torque to specification.
4. Apply dielectric grease to the inside of each spark plug cap and rein-
stall the caps onto the plugs.
5. Turn the engine over several times using electric start. Oil will be
forced in and around the piston rings and ring lands, coating the cyl-
inder with a protective film of fresh oil.
6. If POLARIS fuel system additive is not used, the fuel tank, fuel
lines, and injectors should be completely drained of gasoline.
