Purpose and Specifications

Castrol Magnatec 5W-30 C3 1L is a premium fully synthetic engine oil that clings like a magnet to key engine parts for instant protection from the first turn of the key. It delivers 50% better engine wear protection during critical warm-up, when up to 75% of wear happens, making it perfect for cold starts down to -30°C and high-heat operation up to 150°C.

Approved for top brands like VW 502.00/505.00, BMW LL-04, Mercedes 229.31, and GM Dexos 2, this low-ash formula safeguards diesel particulate filters (DPF) and catalytic converters in modern petrol and diesel engines. It keeps pistons, valves, timing chains, and bearings clean while improving fuel efficiency in stop-start city driving.

• Clings and locks to metal surfaces for non-stop protection
• Reduces friction for smoother running and longer engine life
• Ideal for European cars, SUVs, and hybrids with exhaust after-treatment systems

When to Use / Replace?

Use this oil in vehicles specifying ACEA C3 or matching specs for everyday commuting, short trips, or heavy loads. Replace every 10,000-15,000 km or 12 months, whichever comes first, to maintain peak performance. Shelf life is 4-5 years unopened in cool, dry storage.

Perfect if your car manual lists these approvals and you face frequent cold starts or urban traffic.
