Castrol Edge Extended Performance 5W-20 Motor Oil 1 Quart, Pack of 6

Product Description Castrol® EDGE® Extended Performance 5W-20 is an advanced full synthetic and Castrol®'s strongest motor oil. This hyper premium lubricant exceeds API and GM dexos test limits as well as the performance requirements of ACEA, the world's most demanding motor oil specification. Boosted with our proprietary additive technology, it provides Ultimate Performance and Protection in 7 Critical Areas including the highest level of wear protection and thermal stability along with the strength to maintain your vehicles performance for an extended drain interval of 25,000 miles. Amazon.com Motor oil is made from crude oil and is used to lubricate, clean, and cool engines. Types of motor oil include conventional, synthetic, diesel, bio-based, hybrid (blends of conventional and synthetic), and recycled oils. Motor oil varies in weight and viscosity, as well as additives that some manufacturers add to the oil during the refining process. A numerical code system created by the Society of Automotive Engineers (SAE) grades motor oils according to viscosity--the higher the number between 0 and 60, the more viscous (thicker) the oil is. Most consumer motor oils are graded by two numbers, with the first number indicating cold weather (Winter or "W") performance.SAE 5W-20This oil has a weight of SAE 5W-20, meaning it has an SAE viscosity rating of 5 in cold temperatures and a rating of 20 at normal operating temperature. Always check your vehicle's owner's manual to verify that this is the correct weight of motor oil for your vehicle.Full Synthetic OilThis oil is a full synthetic oil, meaning crude oil is not used in making it. Synthetic oil can be used in vehicle engines instead of motor oils refined from crude oil, and often provides superior mechanical performance over traditional motor oil, including increased gas mileage and reduced engine wear at extreme temperatures. Its complex method of production means it can often cost more than conventional motor oil.
