Cera Tec is a high-tech anti-wear additive, suitable for the use in motor oils as well as manual transmission fluids and compressors. Cera Tec reduces friction and wear due to ceramic compounds that are extremely heat and pressure resistant. Prevents direct metal-to-metal contact, thus increasing the engine service life. The low-friction effect reduces fuel consumption in gasoline and diesel engines. Wear protection for engines, manual transmissions, pumps and compressors. Cera Tec is added to the oil and is self-mixing. Sufficient for 5 liters (5.28 U.S. QT) oil volume. With long-term effect up to 50.000 km (30.000 miles). Not suitable for use with wet clutches! Minimum oil filling of 3 liters (3.17 U.S. QT) is requested for optimum product performance.
