Because of increasingly busy traffic, drivers today are experiencing more and more stop-start driving. Even a normal driver can stop and start as many as 18000 times a year.
Frequent stopping and starting involves more decelerating, more idling and more accelerating, causes pieces of metal to be abraded off the surfaces of critical engine parts, increasing microscopic engine wear.
Castrol MAGNATEC STOP-START contains special molecules that form a self-healing layer that constantly protects against stop-start wear, providing up to 20% better stop-start wear protection*. So even if some molecules are knocked off in the process of protecting your engine, others rush in to restore the protective layer.
