Bio-Diesel and Water Fuel legislation designed to reduce harmful emissions and increasing global demand for diesel has resulted in more and more bio-diesel finding its way into the fuel supply chain.
The increased use of bio-diesel increases the incidence of water contamination problems in diesel. Why? Bio-diesel contains more water than petro-diesel (it is introduced in the production process), it is also hygroscopic which means it absorbs water from the atmosphere. Petro-diesel can absorb around 50 parts per million (ppm) of water whilst bio-diesel can absorb as much as 1500ppm most global fuel standards recommend a maximum water content of 200ppm. As ambient temperatures rise water is absorbed into the fuel, as they fall the water condenses out of the fuel and forms free water. Free water can wreak havoc in your fuel system, this water subsequently accumulates and sinks to the bottom of the tank creating an ideal environment for the growth of "fuel bugs".

There are known to be over 20 species of fuel bugs that can contaminate your fuel storage tank, including the most common Cladisporium resinae. Fungal infestation can 'spoil' the fuel when the sludge and residue is drawn into the engine, which quickly clogs conventional cartridge filters, causing loss of power, narrowing fuel lines and eventually leading to engine breakdown.
