Key Performance Benefits

  • Easier cold starting & reduction in white smoke
  • Emission reductions
  • Reduced noise
  • Improved fuel economy


HiTEC® 4103W is a cost effective cetane improver additive used to raise the cetane number of both petrodiesel and biodiesel fuels. It lowers exhaust emissions, especially NOx, from diesel engines. HiTEC® 4103W allows a refinery to increase it's profitability by upgrading, for example, FCC light cycle oils from cutter stock to diesel fuel valves.


Recommended Dosage

The cetane number of your base fuel will dictate the treat-rate of HiTEC® 4103W additive. Based on EN590 specification fuel, a treat-rate of approximately 300 ppmv will provide two Cetane numbers. Please contact your Afton Chemical representative for specific recommendations.
