Purpose and Specifications

Rislone Ring Seal Smoke Repair is a high-mileage engine oil additive designed to stop blue exhaust smoke, reduce oil burning, and seal worn pistons and rings in older engines over 75,000 km. This 473 ml bottle treats 4 to 6 liters of oil in regular 4, 6, or 8-cylinder gasoline and diesel engines, including turbocharged ones.

It contains high-shear polymers that fill gaps from wear, cushion parts to quiet noisy lifters, and maintain oil flow in hot weather up to 120°C or cold down to -20°C. Add one full bottle every 2,000 km or at every oil change for ongoing protection; a second dose handles severe cases.

When to Use / Replace?

Use it when you notice blue smoke on startup or acceleration, rising oil levels on the dipstick, or fouled spark plugs from blow-by in high-mileage vehicles. Ideal for engines with over 75,000 km showing wear signs. Replace by adding fresh treatment every 2,000 km or 3 months, whichever comes first; shelf life is 5 years unopened.

• Stops smoke immediately or within days of driving
• Works with conventional, high-mileage, or synthetic oils
• Safe for ATVs, motorcycles, and wet clutch applications at 93 ml per liter
