THE SCIENCE INSIDE THE TAB

COMBUSTION HAPPENS IN MILLISECONDS. FEROX HELPS MAKE THEM COUNT.

Inside your engine, fuel, oxygen, heat, pressure, and timing must come together during an extremely short combustion window. When that process is incomplete or inconsistent, some fuel potential is lost and more soot, carbon-rich compounds, and other combustion byproducts can remain.

Ferox is a solid fuel catalyst designed to support the oxidation reactions occurring during that brief combustion event.

FUEL + OXYGEN + FEROX CATALYST → MORE CONSISTENT COMBUSTION → MORE USEFUL WORK + FEWER COMBUSTION BYPRODUCTS
Ferox does not create additional energy. It is designed to help the engine make better use of the chemical energy already stored in the fuel.

COMPLETE COMBUSTION IS THE TARGET.

WITHOUT COMBUSTION SUPPORT
  • Less consistent oxidation
  • More unburned hydrocarbons
  • More soot and carbon-rich byproducts
  • Greater variation between combustion events
  • More fuel potential lost outside useful work
WITH FEROX CATALYST TECHNOLOGY
  • More consistent oxidation
  • More complete fuel participation
  • Fewer incomplete-combustion byproducts
  • More consistent combustion events
  • Better use of the fuel's available energy
THE ENGINE DOESN'T NEED MORE FUEL. IT NEEDS TO USE ITS FUEL BETTER.
Ferox works at the point where fuel becomes power. That is what separates it from treatments focused primarily on storage, injector cleaning, or deposits after they form.
Smoother throttle response
More consistent idle
Less soot and carbon buildup
Better use of every tank
WHY FEROX?

ENGINEERED OVER DECADES. PROVEN IN THE REAL WORLD.

Ferox isn't a new fuel-treatment idea built around a marketing claim. Its catalyst technology reflects four decades of work across everyday vehicles, commercial fleets, industrial equipment, and demanding fuel applications.
40 YEARS

OF COMBUSTION EXPERIENCE

Four decades spent developing and applying fuel-catalyst technology across changing fuels, engines, and operating environments.

BILLIONS OF GALLONS

TREATED WITH FEROX TECHNOLOGY

Ferox catalyst technology has been used across billions of gallons of fuel in consumer, commercial, and industrial applications.

MILLIONS OF DATA POINTS

FROM REAL-WORLD USE

Performance has been evaluated through millions of operational data points—not only controlled demonstrations or isolated testimonials.

TRUSTED WHERE PERFORMANCE MATTERS.

EVERYDAY VEHICLES

Used by drivers looking for smoother performance, cleaner combustion, and a simple treatment at fill-up.

COMMERCIAL FLEETS

Evaluated in high-mileage operations where fuel consumption, idle time, DEF usage, and operating costs can be measured.

HEAVY EQUIPMENT

Used in demanding mining, construction, agricultural, and industrial environments where reliability and uptime matter.

PERFORMANCE APPLICATIONS

Used in racing and high-load environments where consistency, response, and confidence in every tank are essential.

ONE TAB IS SIMPLE. THE TECHNOLOGY BEHIND IT ISN'T.

Ferox combines decades of fuel-catalyst experience with an easy drop-in format. No measuring. No messy liquids. No complicated installation. Just the correct tab for the amount of fuel being treated.

TWO TANKS. YOUR VEHICLE. YOUR RESULTS.

Use Ferox for two complete tanks. If you don't notice a difference in how your engine runs, your purchase is covered by the Ferox Two-Tank Money-Back Guarantee.
