Today even a normal driver can stop and start as many as 18,000 times a year. Frequent stopping and starting involves more decelerating, more idling and more accelerating, causing microscopic abrasion of metal particles from contact surfaces, increasing wear of critical engine parts. Full synthetic Castrol MAGNATEC STOP-START contains Intelligent 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. Covering the latest API and fuel efficient ILSAC specification, MAGNATEC STOP-START 0W-20 can be recommended for use wherever a manufacturer calls for the use of an SAE 0W-20 engine oil. That includes recent model TOYOTA, MAZDA, NISSAN, JEEP and SUBARU vehicles. MAGNATEC STOP-START 0W-20 is also recommended for use in Hybrid vehicles requiring a SAE 0W-20 product.
