A powerful blend of oils and additives that contain no SOLVENTS. Designed to increase power and fuel mileage and also lower exhaust emissions through a more complete combustion.

Lucas Fuel Treatment is formulated for both gasoline and diesel engines, carbureted or fuel injected. It gives your fuel system what it really needs - a blend of super slick oils and additives with a high detergent action that allows the engine to operate at maximum efficiency. Also, it cleans and lubricates the carburetor and injectors and causes the fuel to burn more thoroughly for increased power and less fuel consumption. Lucas Fuel Treatment should definitely be used in vehicles that require leaded fuel because it actually replaces the benefits of lead in gasoline without causing harmful emissions. Use it to pass smog tests. Finally, it totally neutralizes the harmful effects of low sulfur diesel fuel.

Lucas Fuel Treatment complies with the federal low sulfur content requirements for use in diesel motor vehicles and non-road, locomotive and marine diesel equipment engines.

It's incredible and actually works and works well.

A 2003 Chevrolet V8 5.7 L engine with 273,000 miles. The engine is excellent, has excellent combustion, I replaced all the spark plugs, wires and everything I could think of to get rid of the check engine light that indicated a misfire in a cylinder or an EGR related or catalytic related error code. I'd almost given up and was just in the process of changing the EGR thinking that might be defective, thought I would try for the first time this Lucas fuel injection cleaner [Lucas Fuel Treatment]. I added probably the recommended amount, maybe a little more to the existing 20 gallons in the tank and almost immediately the check engine light went off and did not come back on. The engine also appears to start easier and run a little better, but it's too soon to tell as I've just treated it and I've only driven the truck maybe 40 or 50 miles - but by some miracle that check engine light is not coming back on and the engine appears to be running as good as ever. I have tried Chevron Techron many times, thinking it was probably one of the best cleaners available - but I don't think that's true, while it does work your product appears to work much better and I suspect I may have had partially clogged fuel injectors. Because the catalytic converters were replaced 15k miles ago when I bought this 3500 Express 1ton van, the O2 sensors have all been replaced and I would still get this engine misfire error code or emission-related error code. Your product appears to have solved my problem. I just went to Amazon today and ordered another gallon and will be looking into buying much more bulk quantity of your product and putting it in all my engines. It's incredible and actually works and works well. -Richard H.
