When a car engine stops, engine oils drain to the sump. The next time it starts the oil begins to recirculate.  During this time, critical parts can be vulnerable to damage. Up to 75% of engine wear occurs during warm-up. Another severe driving condition is stop and go driving in heavy traffic. When idling on congested highways, loads on critical engine parts are at their peak. Both short trip driving and stop and go driving in heavy traffic are severe conditions that create engine wear.
 
Castrol GTX MAGNATEC is a full synthetic with intelligent molecules that cling to critical engine parts, forming an extra layer that protects from the start and throughout the entire drive cycle.  In fact, the latest sequence IVA test proves that Castrol GTX MAGNATEC offers six times better wear protection than required by the industry standard test limit, making it an excellent choice for consumers who drive in heavy traffic, or take multiple short trips.
