Increasing traffic density in the last 10 years causes engine wear and fuel wastage. That's why no car can perform at its best in heavy traffic, including cars with start-stop technology.
 
That's why we developed the new Castrol MAGNATEC STOP-START, combining Castrol's most efficient fully synthetic base oils with patented DUALOCK molecule technology.
 
DUALOCK MOLECULES:
Creates a strong protective shield.
It reduces the wear that occurs during both engine warm-up1 and stop-start2 driving moments by 50%.
Even during stop-and-go driving, it saves 60 liters of fuel per year.3
 



Non-stop protection from the moment you take action, even in vehicles with the new generation  start-stop engine technology.

1 Sequence tested to IVA API SN wear limit.
2 Tested to CEC OM646LA ACEA wear limits.
3 EUDC (for highways), EPA NYCC (for cities) and Castrol Ultra-Idle Cycle (for traffic congestion) tested in 2015 compared to industry reference 15W-40 oil. It is taken into account that 12.000km is driven per year and  representative driving distribution (60% highway, 30% city, 10% heavy traffic). Results vary depending on road conditions, vehicle type, driving conditions and style
