Lucas, 32 oz, upper cylinder lubricant, with injector cleaner and fuel conditioners. Powerful blend of oils and additives that contain no solvents. Designed to increase power and fuel mileage, and also lower exhaust emissions through more complete combustion. Formulated for both gasoline and diesel engines, carbureted or fuel-injected. A blend of super slick oils and additives with high detergent action that allows the engine to operate at maximum efficiency. Cleans and lubricates the carburetor and injectors, and causes the fuel to burn more thoroughly for increased power and less fuel consumption. Use in vehicles that require leaded fuel because it replaces the benefits of lead in gasoline without causing harmful emissions. Use it to pass smog tests. Complies with federal low sulfur content requirements for use in diesel motor vehicles and non-road, locomotive, and marine diesel equipment engines.
