Castrol EDGE 5W-40 A3/B4 Engine Oil 4L
Hurry up, only 10 items left in stock.
Unlock exhilarating performance and extreme engine protection with Castrol EDGE 5W-40 A3/B4. Today’s engines are smaller, more efficient, and run under significantly higher pressures. Castrol EDGE is formulated with advanced Fluid TITANIUM Technology, which physically transforms its structure—becoming stiffer at points of extreme pressure to keep metal apart and reduce friction by up to 20%.
The A3/B4 specification represents a robust, "Full-SAPS" formulation. It is specifically designed to provide outstanding high-temperature, high-shear protection for high-performance petrol and diesel engines that do not have Diesel Particulate Filters (DPFs), delivering uncompromising horsepower and wear defense.

How do I know if this engine oil is the right one for my car?
How do I know if this engine oil is the right one for my car?
To ensure perfect compatibility, always check your vehicle's owner's manual. You need to match two key things: the viscosity (e.g., 5W-30, 0W-40) and the manufacturer specification/approval (e.g., VW 504.00, BMW LL-04, ACEA C3, API SP). You can find all the specifications and official approvals for this oil listed in the Technical Details table above to compare with your manual.
What do the numbers in the oil's viscosity (like 5W-30) mean?
What do the numbers in the oil's viscosity (like 5W-30) mean?
These numbers represent the oil's thickness and how it flows at different temperatures. The number before the "W" (Winter) indicates how well the oil flows when the engine is cold—a lower number means it flows faster to protect your engine during cold starts. The second number indicates the oil's thickness and protective barrier at normal, hot operating temperatures.
What is the difference between fully synthetic and conventional engine oil?
What is the difference between fully synthetic and conventional engine oil?
Unlike conventional mineral oil which is refined directly from crude oil, fully synthetic oil is highly purified and chemically engineered in a lab, allowing synthetic oils to offer vastly superior protection, better extreme-temperature performance, and longer drain intervals because their uniform molecular structure resists breaking down under high stress.
How often should I change my engine oil?
How often should I change my engine oil?
Most modern cars require an oil change every 5,000–7,500 miles, though vehicles using fully synthetic oil can often go up to 10,000 miles or more. Always follow your manufacturer’s specific mileage and time interval recommendations in the owner’s manual.
