Owners of fleets with diesel engines are aware that diesel fuel is inclined to gel in the winter when the temperature drops and the paraffin in the fuel begins to solidify. Over time, this wax-like substance clogs the fuel line and the fuel filter, and prevents the free flow of fuel, making it harder to start the engine.
Even worse is the presence of water in diesel fuel. In fact, water is the No. 1 contaminant of diesel fuel. Although the fuel is relatively free of water when it leaves the refinery, it (water) enters the mix through several other ways – during the delivery process, through atmospheric variables, condensation and leakage. Care, therefore, should be taken to ensure the purity of the fuel at all points to prevent water from entering the tank.
Condensation inside the tank can cause diesel sludge, an algae-like substance, to form and settle at the bottom of the tank. Debris from the storage tank also can get into the fuel tank and, over time, can get stirred up and enter the vehicle’s engine.
Although one may see a plethora of additives on aftermarket shelves, selecting one that can work throughout the year is key to the most cost effective and efficient answer to diesel fuel related problems.
