Fog the Engine
1. Treat the fuel system with Polaris Carbon Clean, following the
instructions on the can. 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 Premium 4 Syn-
thetic 0W40 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. Oil will be forced in and around
the piston rings and ring lands, coating the cylinder with a protec-
tive 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.
