Traffic congestion has increased significantly over the past decade. This is indeed annoying, but the worst part is that it gradually causes permanent damage to your engine.

To respond to the increasingly urbanized environment, Castrol developed Castrol Magnatec with Dualock technology. Castrol's unique Magnatec Dualock technology is a global innovation. The molecules adhere to critical engine components and lock together to protect the engine from wear during warm-up and stop-start wear. 

Thus, a strong protective field is formed that reduces wear caused during engine warm-up and stop-start by 50%.
