Liqui Moly Cera Tec high tech oil additive contains tiny ceramic particles so small that they easily pass the oil filter. These particles adhere to the metal surfaces in the combustion chamber and prevent metal from scratching on metal. The formulation is so strong that this ceramic protection layer survives even oil changes. In addition to this physical protection there is also a chemical protection further reducing the friction in the engine. The engine runs perceptibly smoother. The reduced friction decreases fuel consumption thus reducing pollutant emissions. Reduction of the wear increases engine life and helps prevent engine breakdowns. Liqui Moly Cera Tec can be mixed with all common motor oils.
