Maintenance and Specifications The Horizontal Fuel Conditioner Module (HFCM) is located on the frame-rail under the driver-side floorboard near the transmission. SCHEDULED MAINTENANCE The scheduled maintenance services in the scheduled maintenance information of this supplement are required because they are considered essential to the life and performance of your vehicle. Use only recommended fuel, lubricants, fluids and service parts conforming to Ford specifications. Motorcraft parts are designed and built for best performance in your vehicle. FUEL REQUIREMENTS Choosing the right fuel The engine is designed to use low sulfur number 1-D or 2-D Diesel fuel only. At temperatures below 20°F (-7°C), number 1-D or winter blend number 2-D fuel is recommended. (See Cold weather operation in the Driving chapter of this supplement.) Diesel fuel containing no more than 5% of biodiesel may be used. Biodiesel fuel is a product derived from renewable fuel sources such as vegetable oil, animal fat and cooking oil. Since it is normal for a small amount of unburned fuel to enter the crankcase and mix with the engine oil, the use of biodiesel requires that the engine oil and filter be changed more often. Refer to the Exceptions section of the Scheduled Maintenance Guide chapter for more information. Do not use home heating oil or any diesel fuel not intended for highway use. Red dye is used to identify fuels intended for agricultural and non-highway use. Damage to the fuel injection system, engine and exhaust catalyst can occur if an improper fuel is used. Do not add gasoline, gasohol or alcohol to diesel fuel. This practice creates a serious fire hazard and engine performance problems. 29 2006 Econoline (eco) Supplement USA (fus)
