Magnatec 5W-30 A3/B4

Clinging molecules, reinvented.

Traffic congestion has increased dramatically; today even a normal driver can stop and start up to 18,000 times1 a year. That’s annoying, but worse, it slowly damages your engine – permanently.

Uniquely, Castrol MAGNATEC’s breakthrough DUALOCK molecules cling to critical engine parts and lock together to:

• Form a powerful force field of protection
• Dramatically reduce both warm-up2 and stop-start3 wear by 50%
• Deliver unique patented protection designed specifically for modern driving

Non-stop protection from every start.
