Pre Emission Test Treatment

Fast acting treatment

Strong, specially formulated treatment to meet new emission testing regulations. Containing 4 specific emission reduction elements, cleaning through the entire fuel system with a highly concentrated formula to restore combustion efficiency , reducing black smoke, exhaust emissions and soot particles.


✓ Specially formulated to pass new emission testing regulations.
✓ Reduces exhaust emissions and soot.
✓ Reduces black smoke.
✓ Improves combustion, engine performance and fuel economy.
✓ Cleans injectors, restoring injector spray pattern.
✓ Assists cleaning of the entire fuel system including diesel oxidation Catalyst and diesel Particulate Filter.


✓ Add one bottle of 500 ml to the diesel fuel tank containing a minimum of 30 litres of fuel.
✓ Drive at least 50 km on the motorway before taking the vehicle to the official emission test.
✓ Can be used as a curative treatment in the event of an emission failure.
✓ For best results, use every 3rd tank filling and use 150 km before MOT test.

Both modern cars and older vehicles have specific requirements, that have a chemical solution to provide the optimal engine performance and driving comfort. Modern fuel systems are highly tuned and therefore more susceptible to the negative effects of chemical reactions in the fuel. These lead to fouling of the fuel system, lack of lubrication, corrosion and other problems. Older vehicles experience problems to obtain the correct air/fuel ratio and combustion efficiency due to accumulation of deposits in the fuel system and wear on the components.
