LIQUI MOLY Oil Smoke Stop

Effective additive that stops blue or black exhaust smoke caused by engine oil burning in the combustion chamber. Stabilizes viscosity and minimizes its loss under high pressure and temperature, significantly reducing oil consumption. Enhances sealing of piston rings and valve stem seals to prevent oil migration into the combustion chamber. Provides additional anti-wear protection and helps restore engine efficiency—especially beneficial for high-mileage vehicles or older engines.
