Rislone says its Ring Seal Smoke Repair is formulated to stop exhaust smoke, reduce oil burning and prevent plug fouling caused by blow-by, which usually is caused by gaps in internal engine parts resulting from excessive wear. Ring Seal Smoke Repair contains viscosity improvers formulated to thicken the oil film between these parts to fill the gaps, and it also contains high-shear polymers to help provide a seal for worn pistons and rings to stop blow-by.
The company says the product, which also is made to cushion and coat engine parts to quiet noisy lifters and reduce wear, retains oil flow characteristics in both hot and cold weather, and can be added to engine oil at any time; it works with conventional, high-mileage and synthetic engine oil. A single bottle added at every oil change or every 2,000 miles treats four to six quarts of oil, according to Rislone; the product also is available in case packs of six 16-ounce bottles.
