Fuel filters ensure that only clean fuel is sent to the engine by screening dirt, debris and other contaminants. Modern fuel systems are very sensitive to contaminants in the fuel and even the smallest particle can erode the fuel pump, valves or injectors, equating to an expensive repair. Fuel filters also maximise performance as clean fuel burns more efficiently. We recommended that the fuel filter is changed every 25,000 to 30,000 miles. For more information on fuel filters,
