Use one quart of Lucas Oil Stabilizer in place of one quart of oil when changing the oil in a car to prevent engine knocking. Do not add an extra quart of the stabilizer after changing the oil.
If the engine is burning or leaking oil, add a quart of Lucas Oil Stabilizer to replace the oil lost. The stabilizer reduces the viscosity of the oil and lowers the oil temperature, resulting in lowered engine energy consumption. Consistent use of Lucas Oil Stabilizer protects an engine in harsh conditions and extends its life. The product also is useful in protecting vehicles from rust and corrosion that develops from not cranking them up for an extended period of time.
