Dieselex Gold Diesel Fuel

Since 1952, Dieselex® Gold has been improving diesel fuel performance. By optimizing eight unique chemistries (fuel additives) in combination with #2 diesel fuel, Dieselex Gold has earned a reputation for restoring lost horsepower, improving fuel efficiency and protecting today’s sophisticated fuel systems.  The eight chemistries include:

  • Detergency to clean injectors for restored horsepower and better fuel economy
  • Cetane improver starts engines fast and produces lower emissions
  • Lubricity Enhancers to extend fuel pump and injector life
  • Corrosion Inhibitors protect metal from rust and corrosion
  • Oxidation inhibitors improve filter and fuel storage life
  • Stabilizing Agents to maintain fuel integrity and extend filter life
  • Demulsifiers to separate "free" moisture from diesel fuel
  • Moisture Control Chemistry to carry dissolved moisture through combustion
