Main Highlights

NO MORE BURNING OIL: Stop your engine from oil burning with the enhanced NoSmoke + StopLeak motor oil additive! Bardahl NoSmoke oil additive gives you top-quality protection and restoration for old engines by "filling in" loose tolerances with an extra-thick formula that reduces oil burning and excessive exhaust smoke. This engine additive stop oil burning solution ensures your vehicle runs cleaner and smoother.
LEAK SEALER: NoSmoke + StopLeak doesn't just reduce burn; it helps seal empty spaces that develop in engines over the years, acting as an engine oil leak sealer to reduce engine noise and quiet noisy lifters. It even helps restore the reliability of dry, brittle seals to stem further oil leaks. Your car won't just run better; it'll sound better too. Stop the smoke and the noise with this effective stop leak oil additive!
CONTROL EMISSIONS: As engines loosen, smoke and pollutants released in exhaust can increase over time, so a car that would have once passed emission standards might slip below acceptable levels. NoSmoke oil additive with StopLeak can not only help reduce or eliminate smoke, but it can also cut down on pollutants released in exhaust to help meet emissions standards. This no smoke oil additive is perfect for maintaining cleaner emissions and protecting your engine.
MAINTAIN AND IMPROVE: Bardahl's NoSmoke + StopLeak is the best motor oil additive for older cars. Not only will it help reduce wear and improve the function of your engine, but it can also restore lost performance and help improve compression over time. Use the best engine oil additive to maintain your car's longevity when you use NoSmoke! This oil additive for car engine treatment is a must-have for any aging vehicle.
