CAT5 1st Blog

CAT5 is a set of catalysts in a liquid carrier that, when added to fuel, is proven to improve fuel combustion efficiency and reduce emissions.

Specially designed to improve MPG, thereby reducing both fuel costs and harmful greenhouse gases.

If CAT5 was introduced to the national fuel supply chain, this would equate to removing 50% off the vehicles from UK roads.

Each engine is slightly different, as are driving styles and vehicular use, so the actual results of the use of CAT5 in your engine will vary to some degree, but should fall within the ranges outlined here.

There are no specialist pumps or equipment etc required to add CAT5 to your vehicle; simply add it straight into your fuel tank or pre-mix in your fuel storage tank.

CAT5 uses certain catalysts to improve combustion efficiency by significantly reducing activation energy, thus improving engine power output and fuel economy. Other catalysts in CAT5 act to reduce emissions through a serious of chemical reactions post-combustion. Reductions in Nitrogen Oxides (NO, NO2, NOx), Carbon Dioxide (CO2), Particulates/Soot (PM/Soot), and Unburned Hydrocarbons (UHCs) are achieved through the use of CAT5.

CAT5 is unlike other fuel additives in that it uses the power of catalysts to deliver improvements in fuel economy and reduced emissions. Let us show you how using CAT5 can improve your bottom line and environmental compliance.

CAT5, again under its original product name, was tested for any sign of engine wear by Innospec, a world leader in the manufacture and sales of fuel additives, to determine any adverse effects CAT5 might have on engine components.
The tests performed were industry-standard tests and showed no detrimental effects on engines.

CAT5 has undergone numerous third-party trials with excellent results. The range of improvements in fuel economy and reductions in emissions levels are illustrated below.

Fuel consumption improvement 3.5% to 15.5%

Carbon Monoxide (CO) 68.8% to 81.4%

Carbon Dioxide CO2) 6% to 8%

Nitric Oxide (NO) 99.4% to 99.6%

Nitrogen Dioxide (NO2) 54.5% to 58.8%

Nitrogen Oxides (NOx) 22% to 94%

Smoke/Opacity 50% to 89%

Particulate Matter (PM) 47% to 60%


Testing confirms that fuel conforming to the following standards, after being dosed with CAT5, will still conform to the relevant standard: 

EN 590 – European Diesel Fuel Standard

ASTM D975 – United States Diesel Fuel Standard

SANS 342 – South African National Standard


**CAT5 will not convert a non-conforming fuel into a conforming fuel.
