Castrol MAGNATEC is a premium fully synthetic engine oil engineered with intelligent molecules that bond to critical engine parts, providing protection from the moment you start your engine.

Unlike conventional oils that drain away when the engine is off, MAGNATEC's molecules cling to engine surfaces, forming a strong protective layer that dramatically reduces wear during the warm-up phase — when up to 75% of engine wear typically occurs.

Suitable for use in a wide range of petrol and diesel passenger cars, MAGNATEC delivers:

• Instant start protection — active defence before the engine even reaches operating temperature
• Continuous protection — intelligent molecules that respond and adapt to your engine's demands
• Proven performance — meeting or exceeding the requirements of leading vehicle manufacturers

Available in a range of viscosity grades and specifications to suit most modern engines. Always check your vehicle handbook or use our number plate checker to confirm the correct grade for your car.
