Diesel Injector Cleaner

Nulon Diesel Injector Cleaner (DIC) is the result of countless hours of research and development into the fuel requirements of diesel-powered engines, to deliver maximum performance, economy and efficiency.

Operators consistently complain of exhaust smoke, poor starting, combustion noise and quality problems associated with fuel storage (particularly for extended periods of time). It is well known that fuel quality varies dramatically for many reasons, including the source of crude from which the fuel is distilled and the time of the year (varying temperature conditions).

Nulon Diesel Injector Cleaner is a powerful multi-functional chemical package formulated to clean diesel injectors and combustion chamber deposits fast. It improves fuel system efficiency and economy, reduces black exhaust smoke and makes cold starting easier. Suitable for all diesel fuel including bio-diesel. 


  • Cleans dirty injectors
  • Suitable for Common Rail and Direct Injection systems
  • Helps clean entire fuel system
  • Improves fuel economy
  • Reduces black exhaust smoke
  • Reduces exhaust emissions
  • Protects fuel system against corrosion
  • Helps prevent algae formation

All of the above benefits assure optimum efficiency of the engine. Extensive testing has proven conclusively that Nulon DIC, used as directed on a regular basis, will afford sustained peak performance of all components associated with the fuel system. Downtime due to injector deposits is minimised. Peak performance is maintained due to efficient combustion, which also ensures fuel economy is optimised. Extensive testing has shown fuel economy improvements making Nulon DIC cost effective from a fuel usage point of view. Further cost savings are attained by reduced maintenance costs and downtime.


For initial treatment pour 300ml into a full tank of diesel. For ongoing maintenance and cleaning, add 50 ml per 50 litres of diesel.

Nulon DIC should be added to all stored fuel, or when filling the tanks of the relevant equipment. (Always add Nulon DIC prior to refuelling to ensure thorough dispersion.) To achieve maximum benefits, Nulon DIC should be used on a constant basis.


  • For conventional injection systems, use at 1ml per liter of fuel or 1 part per 1,000 parts of fuel.
  • For Common Rail Injection systems, use at 2ml per liter of fuel or 2 parts per 1,000 parts of fuel.

Avoid contact with eyes or skin. DO NOT SWALLOW. Keep out of reach of children. Combustible. Keep away from heat or flame. Do not breathe vapour. Wash hands thoroughly after use. Not to be used as a food container.


For advice, contact a Poisons Information Centre (Phone eg Australia 131 126; New Zealand 0800 764 766) or a doctor (at once). If swallowed, do NOT induce vomiting. If in eyes, hold eyelids apart and flush the eye continuously with running water. If skin contact occurs, flush with running water.
