Castrol MAGNATEC 10W-40 is semi-synthetic engine oil that protects and cleanses your engine with Castrol Magnatec intelligent molecules designed to cling to your engine like a magnet, providing an extra layer of protection. Castrol Magnatec’s unique formulation protects from the moment you turn the key, dramatically reducing* engine wear. Now with ultra-refined molecules, for protection, you can see, hear and feel.
Unlike your run-of-the-mill lubricants which run off the engine block once the vehicle is switched off, Castrol Magnatec remains firmly attached like a magnet so even during non-use periods and during cold starts your car remains fully protected.
