Castrol Edge High Mileage 20W-50 Advanced Full Synthetic Motor Oil, 1 Quart, Pack of 6

Castrol GTX High Mileage is a specially formulated motor oil designed for vehicles with over 75,000 miles. It features unique detergency additives that prevent deposit build-up and seal conditioners that help reduce leaks in high-mileage engines. Motor oil is derived from crude oil and is used to lubricate, clean, and cool engines. There are various types of motor oil, including conventional, synthetic, diesel, bio-based, hybrid (a blend of conventional and synthetic), and recycled oils. The viscosity and weight of motor oil, as well as the additives used, can vary among different manufacturers.

The Society of Automotive Engineers (SAE) has developed a numerical code system to grade motor oils based on their viscosity. The higher the number between 0 and 60, the thicker the oil. Most consumer motor oils are graded by two numbers, with the first number indicating cold weather (Winter or "W") performance. The oil in question has an SAE viscosity rating of 20 in cold temperatures and a rating of 50 at normal operating temperature, making it a SAE 20W-50 motor oil.

As a conventional motor oil, this product is refined from crude oil or petroleum products and may or may not have additional additives included after the refining process. Conventional motor oils are more versatile than synthetic or hybrid motor oils, as they are suitable for use with nearly all types of modern vehicle engines, including cars, trucks, motorcycles, ATVs, farm equipment, and more.

This Castrol GTX High Mileage oil is primarily designed for use in high-mileage vehicles, both older and newer models that experience heavy long-distance use. The extra additives included in the formulation are intended to minimize compression loss and condition rubber seals and gaskets, helping to prevent fluid leakage in high-mileage vehicles.

For optimal performance, it is recommended to follow the manufacturer's recommendations outlined in the vehicle owner's manual. The oil offers superior detergency to help prevent deposit build-up and advanced additives to help prevent engine wear. Additionally, the seal conditioners included in the formulation are designed to help reduce leaks in high-mileage engines.
