Fitch® Fuel Catalysts

In Line CatalystMy car seems to chew through a lot more more fuel that it used to, and the price of fuel seems to chew through a lot more cash than it used to! That is why a brochure for the Fitch® Fuel Catalyst caught my eye in the show-room of my local mechanic. The claims were impressive - average fuel savings of between 5% and 12%, increased power, cleaner fuel system and lower emissions. Normally I am skeptical of fuel-saving devices, however with a 90 day and 120% cash-back guarantee, I thought I'd look into these devices a little more!

A Catalyst?

A catalyst is defined as something that "increases the rate of a chemical reaction without itself undergoing any permanent chemical change". All modern cars are fitted with a catalyst in the exhaust system (the catalytic converter) which converts pollutants in the exhaust gas into less harmful gasses. The Fitch® Fuel Catalyst works in the same way - converting unwanted particles in the fuel (gums and resins that cause innefficient combustion) into a more combustible form.

The Fitch® Fuel Catalyst is different to other fuel saving devices, as it is the only true catalyst that causes a chemical reaction to the fuel, rather than putting an additive into the fuel. They are available as an in-line catalyst that is fitted to the fuel line, or a drop-in-tank variety.

How does it work?

Information from the Fitch® Fuel Catalyst website: All hydrocarbon fuels contain gums and resins which cause the fuel molecules of petrol (and diesel) to conglomerate in clusters. These clusters are too large to burn completely in the extremely short time that the burning fuel is in the combustion chamber. Therefore, these unburned molecules enter the exhaust stream as a smoky gas and do not contribute any power to the operation of the engine. The Catalyst dissolves these gums and resins so that these clusters of molecules do not form, allowing all the fuel to be used for power. This is accomplished through a complex chemical reaction, which breaks the long chain hydrocarbons converting them to smaller, higher energy, and more combustible constituents, which burn more efficiently. The theory is verified by the fact that the catalyst fuel consistently produces exhaust emissions reductions of 50% or more in both hydrocarbons and carbon monoxide, thus indicating more complete combustion. Testing by several leading laboratories have confirmed that the Fitch® Fuel Catalyst is actually re-refining the fuel immediately prior to combustion.

  • Increased fuel economy
  • Lower emissions
  • More power
  • Less maintenance
  • Enhanced engine life

Information from the Fitch® Fuel Catalyst website: The combustion improvement caused by the presence of the Fitch® Fuel Catalyst produces a number of benefits. Because the fuel is consumed more completely, less fuel is burned, emissions are lowered and power is increased. In addition, engine oil remains cleaner, longer because blow-by is reduced. Because carbon build up in the engine is also reduced the life of the engine is enhanced. The overall result is a more efficiently running engine. The extent to which these benefits are obtained is a function of the age and condition of the engine, how the engine is being used and the quality of the fuel being burned.
