Purpose and Specifications

Castrol Magnatec Diesel 5W-40 DPF 5L engine oil delivers instant protection from the moment you start your diesel engine. Its intelligent molecules cling like a magnet to critical metal parts such as pistons, bearings, and the valvetrain, forming a strong protective layer that cuts engine wear by up to 50% during cold starts and stop/start traffic.

This synthetic oil is fully compatible with Diesel Particulate Filters (DPF), keeping your filter clean and maintaining engine efficiency without clogging. The 5W-40 viscosity flows easily at cold temperatures down to -30°C for quick startups, while staying thick and protective up to 150°C in high-heat conditions. Perfect for modern diesel SUVs, 4WDs, cars with DPF, and vehicles like Hyundai diesels or those with turbocharged TDI/CRDI engines.

• Key Benefits: Reduces wear by 50% on restarts, handles soot to prevent thickening, exceeds ACEA C3 and API SN/CF standards for top diesel protection.
• Volume: 5 liters - ideal for complete oil changes.
• Shelf Life: Up to 5 years when stored in a cool, dry place.

When to Use / Replace?

Use Castrol Magnatec Diesel 5W-40 DPF in any diesel engine requiring 5W-40 ACEA C3 oil, especially if fitted with DPF or stop/start tech. It's your go-to for city driving, long hauls, or extreme weather - from freezing winters to hot summers.

Replace every 10,000-15,000 km or 12 months, whichever comes first, to keep protection strong. Check your owner's manual for exact intervals, but always swap if oil looks dirty or after 1 year to avoid wear buildup.
