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.

That’s why we created new MAGNATEC STOP-START, combining patented DUALOCK molecule technology with Castrol’s most efficient full synthetic base oils.

Forms a powerful force-field of wear protection
Dramatically reduces both warm-up1 and stop-start2 wear by 50%
Improved Fuel Economy3
