The Fitch Fuel Catalyst transforms gasoline and diesel into a superior quality of fuel, allowing a combustion engine to extract the maximum amount of energy with minimal emissions. Get more Performance out of your engines for less: less money, less pollution and less maintenance headaches.

The Fitch Fuel Catalyst is a patented metal alloy that causes a molecular change in hydrocarbon fuels such as gas, diesel, oil, kerosene, etc. This reaction is similar to the refining process that takes place at the refinery. However, a refinery uses heat and pressure to "crack" octane or refine the fuel, where as the Fitch Catalyst creates a transformation in fuel but the "re-refining" process takes place on board a machine, at a low temperature. As fuel passes over the catalyst, it rejuvenates the gasoline or diesel, allowing for a more thorough combustion process.

An engine operates most efficiently and produces maximum horsepower and torque when it is running on the highest quality fuel. Gasoline and diesel is at its most optimal quality when it is first refined but unfortunately during storage and transportation, the fuel quality drastically diminishes. Sacrificed horsepower, torque and efficiency may be the result of this poorer fuel quality. A less than optimal fuel will also produce more emissions, soot build up, and deposits in engine oil and injectors. The Fitch Fuel Catalyst will boost octane in gasoline, increase cetane in diesel and re-refine the fuel quality, returning it to a superior "refinery" fresh state guaranteeing maximum performance and efficiency from the engine. Unlike additives that require replenishing, the Fitch Fuel Catalyst is warranted for 250,000 miles and does not dissolve or loose its potency.

The Fitch Fuel Catalyst simply improves fuel quality and all engines will experience the benefits:

  • Increased Fuel Economy (1-2.5 mpg)
  • Improved Horsepower & Torque
  • Improved Octane in Gasoline
  • Reduced Emissions & Soot Build Up
  • Extended Engine Longevity
  • Reduced Overall Engine Maintenance

What is the difference between a permanent fuel treatment and an additive?

An additive is usually a chemical added to fuel. Additives must be replenished at each refueling. A permanent fuel treatment affects the fuel but does not become part of it and does not need to be replaced.

What is the Fitch Fuel Catalyst?

A metal alloy composed by a proprietary process that permanently transforms hydrocarbon fuels to a superior quality fuel than what is purchased from a gas station.

How does Fitch work?

Gasoline and diesel is at its most optimal when it is first refined but unfortunately during storage and transportation, the fuel quality drastically diminishes. Fuel is attacked by oxygen, ozone, and microorganisms (bacteria, yeast, and mold) that grow in the fuel creating a less than optimal fuel. A less than optimal fuel will produce less engine efficiency, less performance, more emissions, soot build up, and deposits in engine oil and injectors. By installing a Fitch System, the fuel is treated with the catalyst on board the vehicle, re-refining the fuel to its most optimal state allowing the engine to produce maximum performance, efficiency and lowering emissions and maintenance
