Stop Smoke is a highly effective Viscosity Index Improver providing superior thermal stability to the engine oil, preventing seepage past the piston rings.
Suggested for high mileage or vehicles using excessive amounts of oil between service intervals.
Compatible with wet clutch motorcycles when used at 5% per volume.
Catalytic converter safe.
