Purpose and Specifications

Castrol Magnatec 5W30 C2 1L is a premium synthetic engine oil designed to protect petrol and diesel engines from the first moment you start. Its intelligent molecules cling like a magnet to key parts such as pistons, bearings, and the valvetrain, forming a self-healing layer that cuts engine wear by up to 50% during cold starts and stop/start driving.

This 5W30 oil flows easily in cold weather down to -30°C for quick protection on frosty mornings, while staying strong up to 150°C in hot conditions. It meets PSA B71.2290 and FIAT 9.55535-S1 specs, making it ideal for Peugeot, Citroen, and Fiat vehicles with modern emissions systems. Up to 75% of wear happens during warm-up, but this oil reduces that dramatically for longer engine life.

• Superior cold start protection in temps as low as -30°C
• 50% better wear protection vs. industry standards
• Optimized for stop/start traffic and urban driving
• Fits ACEA C2 and API SN approved engines

When to Use / Replace?

Use Castrol Magnatec 5W30 C2 in vehicles requiring low-friction 5W30 oil with fuel economy benefits. Perfect for daily commutes, city traffic, or highways where frequent starts increase wear. Replace every 10,000-15,000 km or 12 months, whichever comes first, to keep protection strong. Shelf life is 4-5 years unopened in a cool, dry place.

Switch to this oil if your manual calls for ACEA C2 specs or you notice rough idling from wear. It extends engine life, saving on repairs in high-mileage cars.
