Fully synthetic engine-oil additive. Significantly reduces wear. High-pressure anti-wear additive forms a very thin layer on friction pairs inside the engine. The layer has ductile and lubricating properties and is effective for at least 50,000 km. The advantages are as follows: ˜ Significant reduction in wear ˜ Longer service life for the engine˜ Reduced fuel consumption and pollutant emissions due to the energy conserving effect ˜ Optimum engine performance and quieter running.
