Lucas Oil Products

Lucas Oil Products — Motor Oils, Additives & Specialty Lubricants

Lucas Oil Products has been formulating performance lubricants and additives in Corona, California since 1989, building one of the most recognized brands in the automotive, racing, and powersports lubrication market. From the iconic Lucas Oil Stabilizer to a full lineup of synthetic motor oils, gear lubricants, fuel treatments, and specialty greases, Lucas Oil produces products trusted by professional racing teams, engine builders, and everyday drivers who want more from their lubrication than a commodity product delivers.

Motor Oils

Lucas Oil's motor oil lineup spans conventional, synthetic blend, and full synthetic formulations across a wide range of viscosity grades for gasoline and diesel engines. The High Performance Motor Oil series is formulated with a zinc and phosphorus additive package that provides enhanced wear protection for flat-tappet camshafts, high-lift roller cams, and high-pressure valvetrain components in performance and racing engines — a critical consideration as modern API-rated oils have reduced ZDDP content that can be insufficient for older and high-performance engine designs.

Lucas Synthetic Racing Oil is formulated for the sustained high-RPM, high-temperature demands of race engines, with shear-stable viscosity that maintains film strength under the extreme pressure and heat of competition use. Hot Rod & Classic Car Motor Oil provides the elevated ZDDP content required for flat-tappet engines in classic vehicles without the need for separate additive supplementation.

Lucas Oil Stabilizer

The Lucas Oil Stabilizer is one of the most widely used oil additives in the industry, formulated to reduce oil consumption, extend oil life, and provide additional wear protection in high-mileage and high-stress applications. The stabilizer increases oil viscosity and film strength, reducing metal-to-metal contact during cold starts and sustained high-load operation. It's compatible with conventional and synthetic oils and is used by engine builders as a break-in additive for new and rebuilt engines to protect critical surfaces during the initial wear-in period.

Fuel Treatments & System Cleaners

Lucas Fuel Treatment is a concentrated fuel system cleaner and lubricant that cleans injectors, carburetors, and intake valves while lubricating upper cylinder components — particularly important for engines running low-sulfur fuels that lack the lubricity of older fuel formulations. The Upper Cylinder Lubricant and Injector Cleaner series addresses fuel system deposits and injector wear in both gasoline and diesel applications, restoring fuel atomization and combustion efficiency on engines with accumulated carbon buildup.

Gear Oils & Transmission Fluids

Lucas Oil produces gear oils for manual transmissions, differentials, and transfer cases in conventional and synthetic formulations across a range of viscosity grades. The SAE 75W-90 and 80W-90 synthetic gear oils provide excellent low-temperature flow for cold-weather shifting while maintaining film strength at operating temperature. Limited-slip differential additive is available separately for differentials requiring friction modifier content for correct clutch pack operation.

Common Applications

Lucas Oil products cover domestic and import vehicles across all engine types — gasoline, diesel, turbocharged, naturally aspirated, and classic flat-tappet applications. Racing applications include drag racing, circle track, off-road, and road course use. Powersports, agricultural, and industrial applications are also served by the Lucas Oil lineup, reflecting the brand's broad formulation capability across different equipment types and operating environments.

Build Quality & USA Manufacturing

Lucas Oil products are formulated and manufactured in the USA, with quality control processes that ensure consistent additive package concentration and base oil quality across every batch. Lucas Oil's motorsports involvement — including sponsorship of professional drag racing, off-road racing, and circle track series — provides direct feedback on product performance under the most demanding conditions, informing ongoing formulation development.

Installation Notes

Lucas Oil motor oils are direct replacements for OEM-specified oils in the correct viscosity grade. The Oil Stabilizer is added at up to 20% of total oil capacity — account for the stabilizer volume when filling to the correct oil level. Fuel treatments are added directly to the fuel tank at the specified dosage per gallon of fuel. Do not exceed recommended dosage on fuel system cleaners, as excessive concentration can affect fuel system seals and O-rings in some applications.
