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. Lucas High Mileage Oil Stabilizer creates a coating that clings to metallic surfaces, eliminating 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 as well as construction and military vehicles and equipment.
