Liqui Moly Engine Oil Smoke Stop is an engine oil additive designed to reduce oil consumption in both petrol and diesel engines, helping maintain smooth performance even in older or worn engines. It prevents blue smoke from the exhaust, extends engine life, and stabilises oil viscosity under high shear stress.Here are the key features of this product:Piston Ring and Valve Guide Protection: This formula reduces oil consumption by sealing off the gaps around the piston rings and valve guides, preventing oil from slipping into the combustion chamber and minimising smoke.High Shear Stability: The additive stabilises oil viscosity even under extreme stress, ensuring the oil retains its thickness and protective qualities, helping the engine run more smoothly and reliably.Compression Ratio Improvement: By increasing compression, the product helps improve engine efficiency and power output, providing smoother operation and reducing engine noise.Catalytic Converter Protection: It extends the li
