Bardahl No Smoke + StopLeak

The Problem A frequent and critical problem in older vehicles is burning oil that causes exhaust smoke and increased emissions. Excessive smoke indicates that oil is getting past the valves and piston rings and into the combustion chamber. Also, over time seals will become dry, brittle and shrink causing oil leaks that can harm the engine or may cause engine failure. The Solution BARDAHL NoSmoke® +Stop Leak is a “double-action” synthetic formula that treats both problems. First, a chemical solution reduces oil burning and decreases exhaust smoke by “filling-in” the loose tolerances between the moving parts inside an engine. The extra thick formula seals any spaces between the valves and guides, piston rings and cylinder walls. Second, a seal swell agent restores pliability of the seals, which stops any oil leaks. In addition, NoSmoke® +Stop Leak reduces friction, cushions worn bearings, quiets noisy lifters, improves compression and maintains efficient lubrication to improve the ope
