Heavy Duty Oil Stabilizer 1 Qt

Lucas Oil Heavy Duty Oil Stabilizer 1 Qt is a premium motor oil additive designed for mechanics and engine builders who require maximum protection under extreme conditions. This product is particularly beneficial for those running high-horsepower modifications, towing heavy loads, or operating in severe climates. It addresses critical failure points in modern engines, such as inadequate film strength and viscosity retention.

The stabilizer works by increasing the viscosity index and oil film thickness, which helps reduce metal-to-metal contact during startup, acceleration, and high-load operation. Lucas Oil formulations utilize proprietary additives that enhance shear stability, ensuring the oil maintains its protective viscosity longer than base oils alone. This concentrated formula is compatible with mineral, synthetic blend, and synthetic motor oils.

Engine builders preparing high-performance vehicles, fleet operators managing mixed-age powertrains, and technicians servicing engines with bearing knock or excessive valve train noise will find this stabilizer particularly advantageous. The 1-quart format allows for precise dosing, with a typical application involving adding one quart per five quarts of crankcase oil. It's an ideal solution for older engines, turbocharged applications, and vehicles with high mileage.
