Ferox (fuel additive)

Ferox is a fuel additive. It was developed by Wesley Parish in 1985 from work done on experimental burn rate modifiers for solid rocket propellant systems used in the aerospace industry. Ferox was originally designed to lengthen the life engines. Until recently, it has been used predominantly in the marine, mining, and trucking industries. It is now used as a fuel additive in common automobile engines using gasoline, diesel, and others. The newest form is in a small tablet that is added with fuel into the tank to be dissolved.

There is evidence that ferox can lower polluting emissions, improve gas mileage, and reduce deposit build-up. There are also claims of prolonging engine life. However, the extent of these benefits for average fuel consumers is still not clear.

The product has been registered with the United States Environmental Protection Agency.

Ferox works as a catalyst, which lowers the activation energy of the rate determining step to break down build-up within the engine. This allows the carbon deposits to burn off at much lower temperatures.
