Fuel contamination - the biggest cause of engine failure

The main contaminants in diesel fuel are:

  • Dirt and sediment – if present in the fuel system, these result in blockage of the filter and increased wear within the fuel system.
  • Water – is the greatest concern because it is the most common. Water can be met with the fuel during the refuelling process, or due to poor house-keeping practices. Effects of water in diesel fuel can be serious, causing injector tips to blow off, corrosion and reduced fuel lubricity, resulting in premature wear to pumps and injectors.
  • Organic contaminants – Asphaltines and paraffin wax, as residual components from the refining process, will block screens, strainers, filters and even hoses.
The Importance of Fuel Filtration

Diesel fuel is not only the engine’s energy source; it also performs several other key roles:

  • Cooling – by circulating through the injection system and absorbing unwanted heat
  • Lubrication – by separating the moving components in the fuel feed and injection pumps
  • Cleansing – by transferring contaminants to the Fuel Filter(s), where they are removed.
