Lucas Fuel treatment complies with the federal low sulfur content requirements for use in diesel motor vehicles and nonroad, locomotive, and marine diesel equipment engines.

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 and Upper Cylinder Lubricant 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.


Pour Lucas Fuel Treatment directly into fuel tank. 

Recommended dosage is 2-3 ounces of Fuel Treatment per 10 gallons of fuel.

Exceeding the recommended dosage is not harmful to your vehicle.

Easy to use injector lube.
I like Lucas Fuel Treatment because it is concentrated and only requires 3 ounces for 10 gallons of fuel. Injectors are mechanical devises, and therefore require lubrication that gasoline does not have. The cleaning power is an extra benefit.

True Top End Lubricant
This product provides a notable increase in mileage on my trucks. Used in my V-twin Harley's it keeps them quiet in the hottest of ambient temperatures. It works so well in trucks and bikes that I now put it in my fuel for outdoor power equipment.

Necessity for two strokes
I like that it's not a gimmic. It's an upper cylinder lube just like it says. Adding this product to every tank of fuel leaves me with a good feeling that I'm taking care of my motor.
