The Lucas Oil Products High Mileage Oil Stabilizer is a 100% petroleum product, developed in the laboratory and tested in the field for maximum reliability. Made from a specially-blended formulation of premium base oils and petroleum extractives, this oil stabilizer can be used in a wide range of engine and gear box applications. Maximum lubricity is achieved with a mix ratio of 20% Lucas High Mileage Oil Stabilizer to 80% engine / transmission oil. This mixture is much slicker than oil alone, reducing friction and heat to allow optimum mechanical efficiency. Creating a coating that clings to metallic surfaces, this high mileage stabilizer prevents dry starts that create the most damage and wear in an older engine. This product is for use in all engine-driven vehicles, and highly recommended for recreational vehicles, farm equipment, industrial equipment along with construction and military vehicles and equipment.
