Supremium Diesel 1/400


Wynn's Supremium® Diesel is an additive package developed to upgrade the quality of regular diesel fuel to premium-grade diesel fuel, especially in filling stations.

  • Cetane improver: Increases the cetane number of EN 590 diesel fuels by 2 up to 4 points. Reduction of NOx and particulates up to 20%. Reduces fuel consumption up to 4%. Eases cold starting.
  • Detergency: Cleans and keeps clean injectors and fuel system. Maintains and restores optimal engine performance (power). o Reduces black exhaust smoke due to an improved combustion.
  • Anti-foam: Reduces foam formation up to 60%. No splashing back of fuel. Quicker and more complete filling-up of the tank (> 15 %).
  • Corrosion inhibitor: Prevents rust and corrosion in the injection system. Prevents pitting and wear on fuel system components.
  • Lubricity agent: Lubricates and protects fuel pump and injectors.


Recommended for all diesel engines of vehicles.
Also for red diesel fuel (road-construction vehicles, tractors, marine).


Normal dosage : 0,25 % (1 litre for 400 litres diesel fuel).
Add to tank lorry or storage tank before filling up.
For manual mixing without calibrated device.

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.
