Castrol® EDGE® is our strongest engine oil. Advanced full synthetic oil, Castrol EDGE has the strength to maintain a protective layer of oil between engine parts at all times.
Why use full synthetic engine oil? Simply because today's small but powerful engines operate at more than double the internal pressure of the engines made 20 or 30 years ago. This means that the pressure between two moving parts can be as much as 10 tons per square centimeter.
That's the same as the weight of five cars resting on the point of a stiletto heel: which demands a motor oil with the strength to maintain a thin, protective layer at all times. Castrol® EDGE® is an advanced full synthetic motor oil that is liquid engineered using Fluid Titanium Technology to strengthen the oil, reduce friction within the engine and ensure maximum performance across long lasting miles.
Getting it right at every oil change is essential. Your owner’s manual will tell you which industry specification, type and grade of oil the manufacturer specifies, and we’ve also made it quick and easy to see all your options and make the right choice with our Oil Selector tool. Try it now.
