Description

Liqui‑Moly Oil Smoke Stop is a specialised engine oil additive developed to reduce oil consumption in both petrol and diesel engines, particularly those with higher mileage or increased wear. It works by improving the sealing effect at piston rings and valve guides, helping to control oil loss and combustion-related smoke. This formulation effectively prevents blue exhaust smoke and oil mist, stabilises oil viscosity, and counteracts viscosity breakdown caused by engine wear. By improving compression and reducing mechanical noise, Oil Smoke Stop helps restore smoother engine operation while providing additional protection for worn components. Suitable for use in engines with catalytic converters, this additive also helps extend catalyst service life by reducing oil-related contamination.
