Purpose and Specifications

Castrol Magnatec 5W30 C2 4L is a premium synthetic engine oil designed to protect petrol and diesel engines from the first moment you start your car. Its intelligent molecules cling like a magnet to critical 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 traffic.

This 5W30 viscosity 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 running conditions. The 4-liter pack suits most cars, providing enough for a standard oil change plus reserve.

• Protects in all temps: from -30°C cold starts to 150°C highway heat
