Road-Tech High Mileage motor oil is a synthetic blend formula using a unique combination of special conditioning agents and additives. This prevents seals from leaking and reduces the oil consumption that is typical of older, worn engines. Road-Tech High Mileage motor oil is specifically designed for new or late model vehicles with over 75,000 miles. This helps keep the engines running clean and going strong providing an excellent protection against sludge, engine rust, and corrosion. It also resists oil thickening by providing enhanced oxidation control under severe service conditions and low temperature operating conditions.
