SulNOxEco™ Petrol Conditioner

SulNOxEco™ Petrol Conditioner is a green product made with naturally occurring ingredients, is readily bio-degradable and compatible with all petrol/gasoline fuel types and engines.

Benefits of SulNOxEco™ Petrol Conditioner include:

  • Compatible with all petrol/gasoline fuels and engines, simply add product to a fuel tank and SulNOxEco™ will dissipate ethanol and free water in your fuel system – the resultant homogenous fuel will remain stable for months in the tank
  • Improves efficiency and modifies the flame characteristics, thus heavily reducing emissions, and significantly reducing fuel costs
  • Significantly improved lubricity means engines rev more freely with extension to the life of engine lubricant oils, leading to a substantial reduction in engine wear
  • Reduces corrosion from ethanol and extends the life of fuel hoses, fuel pumps, fuel dampers, seals, gaskets, diaphragms and other rubber parts

A natural solution for E10 issues

  • Ethanol will absorb water at a rate 50 times faster than petrol, it does not keep (store) well. As the ethanol continues to absorb moisture, it begins a phase separation – the combined mix sits at the bottom of the fuel tank and causes issues with starting and stalling on hot days
  • The risks of E10 (10% ethanol) are significant for all older petrol cars, estimates of 634,309 cars in total in the UK alone
  • Troublesome ‘phase separation’ is avoided as SulNOxEco™ Petrol Conditioner scavenges and disperses ‘free water’ throughout the fuel therefore not allowing an ethanol/water mixture to form separately at the bottom of the tank.
  • The resultant homogenous fuel will remain stable for months in the tank.

Pre, During and Post Combustion Expectations

  • Offers a more complete combustion
  • Lower exhaust temperature
  • Any grade of fuel being used will produce less soot
  • Reduces contamination of engine oil – preserving the engine
  • Less visible smoke and reduced fouling of ignition and fuelling components
  • Improved fuel economy
  • Reduced engine parts corrosion, reduced failure of lubricating films
  • Longer turbo life and reduced engine maintenance


Compliant to recommended engine manufacturer standards

Manufactured by EcoVadis platinum medal winning Nouryon BV, SulNOxEco™ Petrol Conditioner is compatible with all petrol and gasoline type fuels including EN228 (E5 and E10), ASTM D4814 & IS2896-2017 and is certified to comply with, and not alter, the specification of any of these fuel types.
