Castrol GTX High Mileage 10W-30 Synthetic Motor Oil, 1 Quart, Pack of 6

Product Description Castrol® GTX® High Mileage 10W-30 is specially formulated for vehicles with over 75,000 miles. It's a synthetic blend motor oil that helps extend engine life providing Superior Protection in 7 Critical Areas including corrosion prevention, sludge control, timing and friction wear. It also contains a proprietary additive to protect the emisssion system. Our Phosphorus Replacement Technology reduces harmful phosphorus to protect the catalytic converter and help extend the life of your high mileage vehicle. 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 10W-30This oil has a weight of SAE 10W-30, meaning it has an SAE viscosity rating of 10 in cold temperatures and a rating of 30 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.Conventional Motor OilThis oil is a conventional motor oil, meaning it is refined from crude oil or petroleum products. Conventional motor oils may or may not have additives included after refining. Conventional motor oils are more versatile than synthetic or hybrid motor oils, because they are suitable for use with nearly all types of modern vehicle engines, from cars and trucks to motorcycles, ATVs, farm equipment, and more.High Mileage OilThis oil is primarily designed for use in high-mileage cars and trucks, including both older vehicles and new vehicles that see heavy long-distance use. Extra additives are included to minimize compression loss, and to condition rubber seals and gaskets to prevent fluid leakage in older or high-mileage vehicles.
