Choose the right Synthetic Oil for your car
Castrol MAGNATEC STOP-START combines DUALOCK molecules with our most efficient, fully synthetic base oils to dramatically reduce wear by 50%* and save up to 60L** of fuel a year in congested driving, thus ensuring non-stop protection from every start.
*Tested versus the sequence IV A API SN wear limit. Tested versus the CEC OM646LA ACEA wear limits. **Compared to an industry reference 15W-40 oil as tested in EUDC (for highway), EPA NYCC (for cities), and Castrol Ultra-idle cycle (for congestion). Assumptions: Annual mileage of 12000 km, representative split of driving (60% on highway, 30% in cities, 10% in congestion). Actual results under road conditions may vary according to vehicle type, driving conditions and style.
