Purpose and Specifications

Castrol Magnatec Professional OE 5W-40 1L is a fully synthetic engine oil that clings to metal parts like a magnet for instant protection from the first turn of the key. Its intelligent molecules bond to critical components such as the valvetrain, pistons, and timing chain, reducing wear by up to 50% during startup when most damage occurs.

This 5W-40 oil flows easily in cold starts down to -30°C for quick lubrication, while staying thick and protective up to 150°C in high-heat conditions. It keeps modern petrol and diesel engines clean, supports fuel efficiency, and protects emission systems like Diesel Particulate Filters (DPF) for longer life.

• Instant cold-start protection: Molecules stay on parts even after shutdown
• High-temperature stability: Handles highway driving and heavy loads
• Extended performance: Suitable for 15,000 km or 12 months between changes
• Volume: 1 liter - perfect for top-ups or small engines

When to Use / Replace?

Use Castrol Magnatec Professional OE 5W-40 in vehicles requiring ACEA C3 or API SN/CF specs, including cars with DPF, turbo petrol/diesel engines, and 4x4s. Ideal for city stop-start driving, long highway trips, or extreme weather from -30°C to over 40°C ambient.

Replace every 10,000-15,000 km or 12 months, whichever comes first, to maintain peak protection. Shelf life is 5 years unopened in cool, dry storage.
