MAGNATEC 5W-30 A5

Busy driving, reinvented.

All cars, even those with the latest stop-start engine technology don’t perform at their best in traffic congestion. And congestion has dramatically increased over the past 10 years, causing engine wear and wasting fuel.

Castrol's MAGNATEC combines DUALOCK molecules with their most efficient full synthetic base oils. Uniquely, Castrol’s breakthrough MAGNATEC DUALOCK molecules cling to critical engine parts and lock together to:

• Form a powerful force-field of protection against engine wear
• Dramatically reduce both warm-up* and stop-start** wear by 50%
• Offer non-stop protection and improved fuel economy*** from every start, even for vehicles with modern stop-start engine technology.
