Functional Fluid, Lubricant, Grease (including Additives)

A combination of active agents, specifically developed to clean the intake valves and the combustion chamber of port injected engines. Protects against corrosion in the fuel system.

A combination of additives to clean and maintain the fuel system of port injected and carbureted gasoline engines. Cleans injectors, the combustion chamber and protects against corrosion. Restores proper fuel atomization and improves engine efficiency. Regular use keeps the fuel system in perfect working order.

An effective mixture of additives used to clean and maintain fuel systems of injected or carbureted gasoline engines.Cleans injectors and the combustion chamber, restores proper fuel atomization and improves engine efficiency. Suitable for use as problem solver and for preventive maintenance.

High-tech fuel additive, developed specifically for improved throttle response under partial engine load. Optimizes fuel atomization and combustion, cleans fuel system while providing maximum engine performance and efficiency.

Lucas Extreme Cold Weather Fuel Treatment is a concentrate of our regular fuel treatment with upper cylinder lubricants PLUS a concentration of new Lucas anti-gel agents. This combination sets it apart from all the other fuel treatments on the market. One quart treats 100 gallons of ultra-low sulfur fuel, low sulfur fuel and bio-diesel to -25?F, -40?F and -15?F respectively. Contains special clean burning additives to facilitate a complete combustion burn for more power, better fuel economy and lower emissions. Provides essential lubricity to internal engine components. To add more power, mpg and longer engine life in warm weather conditions, use our regular Lucas Fuel Treatment. This product should more than pay for itself in increased fuel mileage alone.

Diesel Fuel Supplement +Cetane Boost is a winterizer/antigel that is used in the cold winter months to prevent fuel gelling and keep fuel-filters from plugging with ice and wax. When temperatures drop, paraffin (wax) in ULSD fuel will gel stopping fuel from flowing through the engine, and water in the fuel can freeze on the facings of fuel-filters, blocking fuel flow. It provides trouble-free winter operation for diesel fuel. Diesel Fuel Supplement +Cetane Boost is intended for use only during cold winter months when temperatures drop below +30F. Use Diesel Kleen +Cetane Boost (in the silver bottle) for peak performance in non-winter months. If your vehicle will not start or gain power in cold temperatures, use Diesel 911 (in the red bottle).

Permanent pour 'n go head gasket & block repair compatible with all types of antifreeze. Repairs cooling system leaks w/3 unique technologies: military-strength fibers nanotechnology & Cool-X Conditioner-the ultimate solution for all coolant leaks.

Total injector cleaner and performance improver. Endorsed by Cummins. Cleans dirty injectors and prevents injector sticking. Removes both internal and external deposits on fuel injectors. Boosts power. Restores lost power and fuel economy. Contains Slickdiesel Lubricator to protect fuel pumps and injectors from increased wear. Effective in all diesel fuels. Treats up to 100 gallons.

K-Seal HD (heavy duty) for large capacity cooling systems such as trucks/tractors, industrial, AG, and RV engines.
K-Seal HD is the best-selling trade trusted permanent total coolant leak repair. The super concentrated formula not only permanently repairs blown head gaskets it also seals leaks in the radiator, heater core, head, block, water pump and freeze plugs. K-Seal HD mixes with all antifreeze / coolant so there is no need to drain or flush the system before or after treatment, and just one bottle is all you need for engines up to 60 quarts. Simple to use simply Shake, Pour and Go! K-Seal HD can be added via the radiator, top hose or via the expansion tank provided it is safe to do so.
K-Seal HD uses a unique ceramic formula and contains NO sodium silicate or liquid glass so it will positively not clog any part of the cooling system. K-Seal HD also works on Hard Plastic and has been independently tested at Brighton University and conforms to the American Standard ASTM D-3147 for Stop-Leak Additives for Engine Coolants. Guarantee - Once we make the repair it is for the life of the engine.

Lucas Fuel Treatment is for gasoline and diesel fuel. It does not contain alcohol, solvents, kerosene, diesel fuel or anything else that would be useless or harmful to engines. Low sulphur diesel fuel and reformulated gasolines have had the polymers removed from them, not because the polymers were harmful but because they were attached to the aromatics (fumes) in the fuels. In their zest to rid our air of gasoline and diesel fumes, our government has stripped our fuel of its main lubricants and, in the process, a great deal of its power. It replaces those polymers with a concentrate that makes the fuel slicker and more powerful than it was originally. In fact, the user usually picks up more than enough fuel mileage to pay for the fuel treatment itself. Lucas Fuel Treatment lubricates rings and cylinder walls for longer life. It causes more combustion for more power and higher fuel mileage with FEWER EMISSIONS. Lucas Fuel Treatment cleans and lubricates valves, pumps, carburetors, injectors and compression rings. It is an absolute must for rotary pumps! It safely replaces the need for lead in older engines.

Lucas Octane Booster is a genuine performance enhancer! It has been tested and proven to deliver at least three times more Boost than most other brands. It is suitable for use in fuel injected, carbureted, throttle body and rotary engines. It?s safe for turbos, oxygen sensors and catalytic converters. Lucas Octane Booster contains specific upper cylinder lubricants that ensure easier piston travel and valve seat protection. It also ensures maximum life and performance from pumps, injectors and carburetors. Lucas Octane Booster eliminates spark knocks, pinging and dieseling. It promotes clean fuel burn for fewer emissions and more MPG. Use with each fill-up for maximum performance and fuel mileage. It treats up to 25 gallons of leaded or unleaded gasoline. Lucas Octane Booster is safe for use in any engine on the track or on the street. Remember: When comparing other brands of octane booster, 10 points equal only one octane number. Not recommended in 2-Stroke engines.
