Castrol Magnatec Stop-Start 5W-30 A5 is a full synthetic engine oil made for the way most of us actually drive: short trips, school runs and crawling through traffic. Every time your engine restarts, especially after sitting idle, oil has drained away from key parts and that’s when most wear happens. Magnatec is designed to tackle exactly that, with intelligent molecules that cling to engine surfaces even when the car is switched off, so there’s a protective layer already in place the moment you turn the key.
That makes it a strong choice for vehicles with stop-start technology, but it’s just as effective in any petrol, diesel or hybrid engine that calls for a 5W-30 A5/B5 oil. The 5W-30 viscosity flows quickly on cold starts and holds up at full operating temperature, giving consistent protection in all driving conditions. The 6L bottle covers a full oil change for most passenger cars and SUVs, with some left over for topping up between services. Always check your owner’s manual or use My Garage to confirm the right oil for your vehicle.
Note: Not suitable for diesel vehicles fitted with a Diesel Particulate Filter (DPF).
