Lucas Oil Fuel Treatment concentrate 5.25 oz (Pack of 24) — cleans injectors, restores power, improves MPG

Lucas Oil 10020 Fuel Treatment is a concentrated additive that cleans, lubricates and protects fuel systems to improve combustion, restore power and support better fuel economy.

Formulated for both gasoline and diesel engines, this Lucas Oil concentrate combines detergents, lubricants and corrosion inhibitors to help remove deposits, neutralize contaminants and protect critical fuel-system parts. It’s designed for routine use — add at regular intervals to maintain injector cleanliness, reduce fouling and help your engine run more efficiently without changing fuels or hardware.

How does this treatment improve engine performance?

By dissolving and flushing varnish, gum and carbon that build up inside injectors, carburetors and combustion chambers, the formula helps restore proper spray pattern and fuel flow. That can translate into smoother acceleration, fewer misfires and a more responsive throttle across a range of operating conditions.

• Removes deposits from fuel injectors and carburetor jets
• Improves atomization for cleaner combustion
• Reduces hesitation and restores lost power

Will it help save money at the pump?

Yes — when fuel burns more completely, less energy is wasted and fuel economy can improve. Regular application of this additive helps reduce excess emissions and unburned fuel, which can lead to measurable gains in miles per gallon for many vehicles.

• Formulated to increase MPG by improving combustion
• Suitable for gasoline and diesel so one product fits mixed fleets
• Packaged in small, accurate doses to treat multiple tanks affordably

How does it protect the fuel system and components?

Beyond cleaning, the blend includes lubricants and corrosion inhibitors that coat internal parts to reduce wear and guard against rust. This protective layer helps extend the life of pumps, injectors and other fuel-system components while neutralizing harmful sulfur compounds.

• Lubricates pumps and injectors to minimize wear
• Neutralizes sulfur and contaminants in fuel
• Prevents rust and corrosion during storage and use

How often should I use Lucas Oil Fuel Treatment?

For maintenance, add the recommended dose each time you refuel or approximately every 3,000 miles to prevent carbon and gunk accumulation. For heavy deposits or neglected systems, an initial treatment regimen may be needed before switching to a regular schedule.

• Add to tank at each fill-up or every ~3,000 miles for ongoing care
• Use full dose for cleaning; repeat as recommended for stubborn buildup
• Safe for older engines and can replace the need for lead in specified applications

Who is this for? This Lucas Oil 5.25-ounce treatment in a 24-count pack is aimed at vehicle owners, fleet managers and equipment operators who want a straightforward, preventive fuel system solution. It’s especially useful for mixed fleets running gasoline and diesel, classic cars that need lead replacement protection, or anyone looking to preserve injectors, pumps and carburetors while improving throttle response and fuel efficiency.
