If you were to look deeply into what makes up your fuel, you would be likely to find a range of contaminants potentially causing harm to your engine. Contaminated fuel can lead to vehicle downtime and costly repairs, especially to expensive common rail systems and components. Modern engines are increasingly requiring better fuel filtration technology to ensure you are delivering the cleanest fuel to your vehicles fuel system. The most common contaminants found in fuel include:
Particulate & Debris
Enters when the fuel is transferred between storage tanks, and when exposed to the atmosphere. Particulate in the fuel can disrupt engine combustion, block the fuel system and cause wear on injectors.
Water in fuel causes corrosion and will erode injector nozzles. It can negatively affect the combustion process, reduces the lubricity of the fuel and consequently damage system components. Water enters fuel from storage tanks, and from condensation caused by cooling temperatures.
Often a component of the fuel, it can drop out in cold conditions (also known as gelling).
Can grow in any free water in the fuel tank.
Fuel Degradation Products
Fuel by-products result from the thermal and oxidative instability of fuel prior to combustion.
Found naturally in crude oil, this can often be found in refined oil.
Enters the system from leaks in fuel lines or system connections.
