Castrol EDGE 5W-30 C3 5L is a premium fully synthetic engine oil that strengthens under pressure to protect your engine from wear, keeps it clean for better power, and ensures smooth starts even in cold weather. It's perfect for modern cars needing top protection without hurting fuel economy or emissions systems.

Purpose and Specifications

This oil uses special Fluid Titanium technology that makes the oil film twice as strong when your engine needs it most, cutting friction between metal parts and preventing damage. It meets key standards like ACEA C3, API SN/CF, and approvals from Mercedes MB 229.51, VW 502.00/505.00/505.01, GM dexos2, plus Renault and others. Ideal for petrol, diesel, and hybrid engines in brands like VW, Audi, BMW, Mercedes, Opel, and Renault.

• 5 liter volume for full oil changes
• 5W-30 viscosity: Flows easy when cold (down to -35°C) and stays stable when hot
• Reduces deposits for max engine response and efficiency
• Low oil burn-off means less top-ups
• Supports diesel particulate filters (DPF) for cleaner running

When to Use / Replace?

Use this oil if your car manual calls for 5W-30 with ACEA C3 or matching specs – check for those VW, MB, or dexos logos. Replace every 10,000-15,000 km or yearly, whichever comes first, to keep protection strong. It handles freezing winters down to -35°C for reliable starts and high heat up to 230°C without breaking down. Unopened shelf life is about 5 years in a cool, dry spot.
