What is diesel bug

Diesel bug is a type of microbial contamination that can occur in diesel fuel. It is caused by the growth of bacteria, fungi, and yeasts in the fuel. These microbes thrive in the presence of water and fuel, and they can multiply rapidly in the right conditions.

Diesel bug can cause a number of problems, including:

  • Engine performance problems, such as poor fuel economy, loss of power, and stalling.
  • Clogging of fuel filters and injectors.
  • Damage to fuel tanks and pipes.
  • The formation of gums and varnishes, which can block fuel lines and injectors.

The best way to prevent diesel bug is to keep your fuel clean and dry. You can do this by:

  • Using a fuel stabiliser to inhibit the growth of microbes.
  • Keeping your fuel tanks and lines clean and free of water.
  • Storing your fuel in a cool, dry place.

If you suspect that your fuel may be contaminated with diesel bug, you should have it tested by a qualified technician. If the fuel is contaminated, it will need to be cleaned and treated before it can be used.

Here are some additional things to know about diesel bug:

  • It is most common in diesel fuel that contains biodiesel. Biodiesel is hygroscopic, which means that it attracts water. This provides the perfect environment for microbes to grow.
  • Diesel bug can be difficult to detect, as it can be invisible to the naked eye. However, there are a few signs that can indicate that your fuel may be contaminated, such as:
    • A foul odour, such as rotten eggs.
    • A cloudy or discoloured appearance.
    • The presence of a slimy substance in the fuel.
  • If you find diesel bug in your fuel, it is important to take action to remove it. Contaminated fuel can damage your engine and fuel system, and it can also be a fire hazard.
