Lucas Oil

Lucas Oil Products is a family-owned lubricant company founded in 1989 in Corydon, Indiana, by Forrest and Charlotte Lucas. The company grew primarily on the back of its fuel additive and engine oil additive lines — the upper cylinder lubricant fuel treatment (part number 10013) became one of the best-selling fuel additives in the United States, notable for its wide-format gallon jugs and a large owner base on Amazon.

The brand is heavily associated with motorsport sponsorship (NASCAR, NHRA, off-road racing) and has built retail distribution through auto parts chains, farm supply stores, and online channels. Lucas products span fuel treatments, engine oil additives, gear oils, hydraulic fluids, and appearance products. The brand's detailing product line is less prominent than its lubricant side; the core identity is engine and drivetrain chemistry rather than exterior care.
