5W/40 is a synthetic motor oil that meets the performance requirements of modern engines. Thanks to its superior thermal and oxidation stability, it maintains performance throughout the longest oil change interval recommended by vehicle manufacturers. With a high viscosity index, it delivers outstanding performance under varying weather conditions. Its excellent fluidity in cold weather ensures quick lubrication of engine parts during the initial start-up, protecting the engine from wear. Its low volatility reduces oil consumption, helping to decrease hydrocarbon emissions.
