Castrol MAGNATEC 10W-40 A3/B4 4L
Traffic congestion has increased significantly over the past decade. That’s annoying, but worse, it slowly damages your engine – permanently.
To respond to increasingly urbanised environments, we developed Castrol MAGNATEC with patented DUALOCK technology. Castrol's unique MAGNATEC DUALOCK technology is a world first. The molecules cling to critical engine parts and lock together to protect the engine against warm-up wear and stop-start wear. This forms a powerful force-field of protection reducing both warm-up wear and stop-start wear, each by 50%*.
