Purpose and Specifications

Castrol EDGE 0W-30 A3/B4 1L is a full synthetic motor oil with Fluid TITANIUM technology that strengthens under extreme engine pressure, reducing friction and unlocking maximum performance. It flows easily like a 0-weight oil in cold starts down to -40°C for quick protection, then acts like a 30-weight oil at full operating temperatures up to 150°C or higher, preventing metal-to-metal contact and power loss.

This oil delivers superior wear protection, fights deposits, and boosts fuel efficiency and horsepower compared to thicker oils, making it ideal for modern gasoline, diesel, and hybrid engines requiring ACEA A3/B4 specs. Recommended by leading European car makers like BMW, Mercedes, and VW, it sustains peak performance over the full drain interval.

When to Use / Replace?

• Use it in: High-performance European cars, hybrids, or any vehicle specifying 0W-30 A3/B4 oil for extreme pressure protection during hard driving, towing, or racing.
• Replace every: 10,000-15,000 km or 12 months, whichever comes first, based on your owner's manual or oil life monitor—shorter intervals for severe conditions like dusty roads or frequent short trips.
• Shelf life: Up to 5 years unopened when stored in a cool, dry place.
