Purpose and Specifications

Castrol EDGE 0W-40 A3/B4 is a full synthetic engine oil engineered for modern petrol, diesel, and hybrid vehicles that demand maximum performance and protection. This premium oil is formulated with Castrol's patented Fluid TITANIUM technology, which strengthens under pressure to reduce friction and protect your engine when it matters most.

The 0W-40 viscosity rating means the oil flows easily in cold temperatures (down to -45°C) while maintaining protective thickness at high engine temperatures. This makes it ideal for year-round driving in varying climates.

Key Benefits

• Friction Reduction: Reduces power-robbing friction by up to 10%, helping your engine run more efficiently and smoothly
• Extended Protection: Provides complete engine protection for the entire drain interval, even under extreme pressure and high-stress driving
• Better Fuel Economy: Improved fuel efficiency through advanced friction management
• Superior Cleanliness: Keeps engine pistons cleaner, maximizing engine performance and longevity
• Viscosity Stability: 3X stronger against viscosity breakdown compared to leading full synthetics, maintaining protection over extended drain cycles

When to Use / Replace?

Oil Change Interval: Replace every 10,000 to 20,000 kilometers (or 6 to 12 months), depending on your vehicle manufacturer's recommendations and driving conditions. Always consult your owner's handbook for the exact interval.

Suitable For: Vehicles requiring ACEA A3/B4, API SP, or earlier specifications. Approved for use in BMW, Mercedes-Benz, Porsche, Renault, Volkswagen, and Ford vehicles.
