Common problems associated to Diesel fuels

---

Any and all of these contaminants will eventually lead to break downs or engine failure.

These types of contamination can be introduced from many different sources throughout the supply chain of the diesel fuel as well as within the storage tank itself. Any one of these contaminants can cause complete engine failure.

Almost everything on Earth contains elements of water; oil and fuel are no exceptions. While very small amounts exist in fuels to start with, stored fuel will become a breeding ground for the microbial bacteria and over time, the levels of damage change from dissolved to emulsified and finally free.

• Dissolved - Dissolved water in oil is the presence of water but, unnoticeable to the eye. The water continues to develop until saturation point where water visibility begins.
• Emulsified - At the point of saturation, a cloudy appearance will be the tell-tale sign that the water/oil mixture has become emulsified.
• Free - The most developed stage of fuel contamination is when free-flowing puddles of water appear within stored oil. At this point, bacterial contamination and growth is boosted.

The contaminants found in fuel can be made up of a number of things, predominantly Hormoconis Resinae, which is typically the main contaminant when microbial contamination is present, along with bacteria Pseudomonas Aeruginosa, and fungi such as yeasts and moulds like Yarrowia tropicalis.

Solid contaminates can be any of the following

• Solid Particle Contamination
  • Rust
  • Dirt
  • Gums
  • Wax
  • Soot
  • Organic Compounds
