Lucas Oil Oil Additives

Lucas Oil Oil Additives: Engine Protection Built on a Legacy

When it comes to oil additives, few names carry as much weight as Lucas Oil. Founded in 1989 by trucker Forrest Lucas and his wife Charlotte, the company was built on a simple but powerful idea: create and produce better working oils than those currently available on the commercial marketplace. That mission has never been more evident than in their oil additive lineup, which remains the cornerstone of the brand.

Where It All Started: The Heavy Duty Oil Stabilizer

The company's very first product was the Heavy Duty Oil Stabilizer — and it remains iconic today. Lucas Oil Stabilizer is a 100% petroleum product formulated to eliminate dry starts and reduce friction, heat, and wear in any type of engine. It allows motor oils a higher degree of lubricity which reduces oil consumption and operating temperatures. What makes it especially versatile is its compatibility: since it is pure petroleum, it can safely blend with all other automotive lubricants, even synthetics, ATF, and mineral oil.

For owners of older or high-mileage vehicles, the High Mileage Oil Stabilizer takes protection even further. It creates a coating that clings to metallic surfaces, eliminating dry starts that create the most damage and wear in an older engine. It retains its viscosity and shear stability at high temperatures, allowing engines to operate at higher temperatures and more extreme conditions without the danger of bearing or component failure.

Targeted Solutions: Stop Leak and Complete Engine Treatment

Lucas Oil's additive lineup goes well beyond stabilizers. The Engine Oil Stop Leak is a targeted formula for engines dealing with seal degradation. Lucas Engine Oil Stop Leak is an all-new formulation of Lucas additives and very specific base stocks designed to stop seal leaks in engines. It is compatible with petroleum, semi-synthetic, and full synthetic motor oils, renews worn seals without risk of damage or eventual corrosion, reduces engine noise and oil consumption while raising oil pressure, and contains no harmful solvents.

The Complete Engine Treatment is another standout — a dual-purpose formula that works in both the oil and fuel system. When added to fuel, it cleans and lubricates all components from the fuel tank to the cylinders, removes deposits, protects against corrosion, and helps the fuel burn more completely — lowering emissions, improving fuel mileage, and increasing power.

What Sets Lucas Oil Additives Apart

Lucas Oil additives are built around a philosophy of proactive, preventive engine care rather than reactive repairs. Their additives are engineered to complement — not replace — conventional and synthetic motor oils. The brand's credibility in this category is well established: according to industry analysis, Lucas Oil accounts for nearly all of the oil additives segment's recent growth and is one of the leading brands in the category.

Key benefits found across the Lucas Oil additive range include:

• Extended oil life through special anti-oxidant properties that help extend the life of your oil, allowing longer intervals between oil changes.
• Superior engine protection that shields against extensive wear and extreme temperatures, creating a protective barrier on critical engine parts and guarding against corrosion, rust, and harmful deposits.
• Improved engine cleanliness by preventing deposits, and better protection against oxidation and corrosion.
• Broad compatibility — most Lucas oil additives work across gasoline and diesel engines, new and high-mileage alike.

Whether you're protecting a brand-new engine or squeezing more life out of a high-mileage workhorse, Lucas Oil's oil additives offer a proven, petroleum-based approach to engine longevity. Explore the full range from Lucas Oil and find the right additive for your application.
