The Lucas Oil Fuel Treatment – 5.25 Ounce is a powerful, solvent-free fuel additive designed to clean, lubricate, and protect your entire fuel system. Known as a “tune-up in a bottle,” it helps improve engine efficiency by promoting more complete combustion, which can increase power and enhance fuel mileage. By reducing excess exhaust emissions, it supports smoother engine performance and more consistent operation.

Formulated for both gasoline and diesel engines, carbureted or fuel injected, this advanced blend of super-slick oils and high-detergent additives works to clean injectors and carburetors while extending the life of pumps and fuel system components. It also neutralizes the harmful effects of low sulfur fuels and replaces the lubricating benefits traditionally provided by leaded gasoline—without producing harmful emissions. Each 5.25 oz bottle treats up to 25 gallons of fuel, making it ideal for routine maintenance and performance support.
