Our experts are on hand to advise our clients of the impact current legislation has on the quality and longevity of fuel and discover how this could impact the operation running of their business.
There are many types of fuel contamination found in gas oil, it only takes one of these contaminates to negatively affect your stored fuel supply.
WHAT IS FUEL CONTAMINATION?
There are many varying types of fuel contamination. Contamination can either be caused by something foreign entering the tank, such as water which then develops microbial growth (AKA diesel bug), or by the fuel itself degrading and producing sludge and damaging molecules.
Water is the arguably the most damaging contaminate to find in your fuel tank as it causes many other contamination chain reactions. Whether it's free, emulsified or dissolved water, this type of contamination can be rapid and cause long term damage to engines.
With water contamination, the risk of microbial growth increases. With the right conditions, microbial growth will occur at the fuel & water interface. A large layer of sludge can form quickly and block filters. Complications with fuel stability and tank corrosion can also occur.
