Rislone High Mileage Ring Seal Smoke Repair 16oz

Rislone® Ring Seal® Smoke Repair is formulated to help stop blue exhaust smoke, reduce oil burning and prevent plug fouling caused from “blow-by”. Blow-by is usually caused by gaps in internal engine parts resulting from excess wear. Ring Seal contains high-shear polymers which provide a seal for worn pistons and rings to stop blow-by.

High mileage formula is specifically designed for older higher mileage engines. Viscosity improver cushions and coats engine parts helping to reduce wear and quiet noisy engines. All weather formula retains oil flow characteristic in hot and cold weather.

Works on gasoline and diesel engines with conventional, high mileage and synthetic engine oils. Can be added anytime, top off oil when low or while changing oil.
