Maintenance and Specifications The Horizontal Fuel Conditioner Module (HFCM) located on the frame-rail under the driver-side floorboard near the transmission. SCHEDULED MAINTENANCE The scheduled maintenance services in the General Owner's Information section 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 The engine is designed to use low sulfur number 1-D or 2-D diesel fuel only. At temperatures below -7°C (20°F), number 1-D or winter blend number 2-D fuel is recommended. (See Cold weather operation in the Driving section of this supplement.) Do not use fuel intended for agricultural use (agricultural fuel is dyed red), home heating oil or any diesel fuel not intended for 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. It should not be necessary to add any aftermarket additives to your fuel tank if you use a properly formulated diesel fuel that meets the ASTM D 975 industry specification. Aftermarket additives can damage the injector system or engine. Do not blend used engine oil with diesel fuel under any circumstances. Blending used oil with the fuel will significantly increase your vehicle's exhaust emissions and reduce engine life due to increased internal wear. 34
