Castrol MAGNATEC STOP-START with DUALOCK technology dramatically reduces engine wear by 50%*. For non-stop protection and improved fuel economy from every start.
Castrol MAGNATEC STOP-START with DUALOCK technology has been designed to provide non-stop protection and improved fuel economy from every start.
Even for vehicles with the latest stop-start technology.
Traffic congestion has increased dramatically over the past decade, causing engine wear and wasting fuel. It is getting more severe and more challenging - for drivers, their engines, and their engine oil. Constant decelerating, idling and accelerating increases microscopic engine wear, with metal fragments worn from the surfaces of critical engine parts, turning into damaging wear particles. All cars, even those with the latest stop-start engine technology, don’t perform at their best in such conditions.
To respond to this changing environment, we have developed Castrol MAGNATEC’s DUALOCK technology. It is a result of over 10 years of research and development by Castrol's technologists in partnership with one of the world's leading universities. Castrol DUALOCK technology uses the combination of warm-up wear molecules and stop-start wear molecules. They lock together at the molecular level to form a powerful force-field of protection.
50% less warm-up wear*
The original intelligent molecules still cling to critical engine parts to protect against warm-up wear.
50% less stop-start wear*
The new molecule clings to protect against stop-start wear.
Powerful force field of protection
They lock together at the molecular level to form a powerful force-field of protection.
To ensure that the engines with the latest stop-start technology perform at their best, Castrol MAGNATEC STOP-START combines DUALOCK molecules with our most efficient fully synthetic base oils. This unique combination dramatically reduces engine wear by 50%* and improves fuel economy. It has also been successfully tested in hybrids.
Castrol MAGNATEC STOP-START offers non-stop protection and improved fuel economy** from every start, even for vehicles with the latest stop-start engine technology.
