Castrol EDGE: our strongest motor oil
Castrol EDGE is an advanced full synthetic motor oil that’s been specially formulated with the strength to withstand the intense forces of high output engines and provide protection and performance over the entire drive cycle. We offer a full range of EDGE products to ensure we have the right product for every type of vehicle and driver.
Why use a full synthetic engine oil? Simply because advances in modern technology have enabled engines to generate more power in a much smaller footprint than ever before. This creates extreme internal pressure, friction and operating temperatures that can breakdown a weaker engine oil and leave critical parts vulnerable to wear and fatigue.
Choosing the right engine oil is essential to protect your investment and ultimately get the most out of your car. We recommend following the guidance of your vehicle manufacturer for the industry specification and viscosity grade best suited for your car. This information can be located in your vehicles owner’s manual. We’ve made the selection process quick and easy with our Oil Selector tool, which also provides other important information to ensure proper maintenance. Try it now.
