The Lucas Oil High Mileage Oil Stabilizer is a specially blended formulation of premium base oils and petroleum extractives to be used as an additive to existing engine or transmission oils. The High Mileage Oil Stabilizer reduces heat and friction, fights off sludge, raises oil pressure, and eliminates the noise and oil consumption associated with worn engines. It 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. Simply mix a ratio of 20 percent Lucas High Mileage Oil Stabilizer to 80 percent engine/transmission oil.
