Rislone® Ring Seal® Smoke Repair is formulated to help stop blue exhaust smoke, reduce oil burning, and prevent plug fouling. Ring Seal contains high-shear polymers that form a seal for worn pistons and rings to stop blow-by. High mileage formula is specifically designed for older engines with higher mileage. The cleaner's all-weather formula retains oil flow characteristics in hot and cold weather, so you can add more anytime or simply top it off when low.
