Diesel RCO 3.1


Wynn's Diesel RCO 3.1 is a combination of additives developed to reduce diesel fuel consumption and emissions.

  • Improvement of the fuel economy by 3,1 % during the test for heavy trucks UTAC 60NERV.
  • Considerably reduces exhaust gas emissions during the test for heavy trucks 60NERV :
  • o 3,1 % reduction CO2
  • o 20 % reduction NOx
  • o 45 % reduction of hydrocarbon emissions
  • Complete cleaning of the fuel system.
  • Instantly cleans and protects injectors and restores and maintains the ideal spray pattern of the injectors.
  • Keeps EGR valves and turbochargers clean.
  • Restores combustion and engine performance.
  • Prevents clogging of the fuel feed lines and fouling of the fuel filter.


For all diesel engines, including common rail and pump/injector systems. For diesel fuel and bio diesel up to B30.


Normal dosage : 0,1 % (1 litre for 1000 litres diesel fuel).


PN 39410 – 1000 l
PN 39499 – 200 l



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.
