Fuel and Refueling Look for a label on the fuel pump to confirm the amount of biodiesel contained in a diesel fuel. Biodiesel content is often indicated with the letter B followed by the percent of biodiesel in the fuel. For example, B20 indicates a fuel containing 20% biodiesel. Ask the service station attendant to confirm the biodiesel content of a diesel fuel if you do not see a label on the fuel pump. Biodiesel fuels degrade more easily than diesel fuels not containing biodiesel and should not be stored in the fuel tank for more than 1 month. If you plan to park or store your vehicle for more than 1 month, then you should empty your vehicle fuel tank of biodiesel fuel. You should fill the tank with a pure petroleum-based diesel fuel and run your vehicle for a minimum of 30 minutes. Note: Degraded or oxidized biodiesel can damage fuel system seals and plastics and corrode steel parts. During cold weather, if you have problems operating on biodiesel, you may need to use a diesel fuel with lower biodiesel content, try another brand, or discontinue the use of biodiesel. Do not use alcohol-based additives to improve cetane quality, to prevent fuel gelling or any other use. The use of alcohol additives may result in damage to the fuel injectors and system. See Technical Specifications (page 57). Your warranty may not cover repairs needed to correct the effects of using an aftermarket product that does not meet Ford specifications in your fuel. Note: Ultra Low Sulfur Diesel fuel is designed to meet the emissions standards for the 6.7L engine and is backward compatible as well (for example, it can be used in the 7.3L, 6.9L, 6.4L and 6.0L diesel engines in Ford vehicles. Fuel And Water Separator Your vehicle is equipped with a diesel fuel conditioner module located on the frame-rail under the driver-side floorboard near the transmission. You should drain water from the module assembly whenever the warning light comes on and the message center directs you to drain the water separator. This will occur when approximately 0.32 pints (150 ml) of water accumulates in the module. If you allow the water level to exceed this level, the water may pass through to the engine and may cause fuel injection equipment damage. Draining the Diesel Fuel Conditioner Module (DFCM) WARNING Your vehicle must be stopped with the engine off when draining the Diesel Fuel Conditioner Module. Fuel may ignite if the separator is drained while the engine is running or vehicle is moving. Diesel Fuel Additives It should not be necessary to add any aftermarket additives to your fuel if you use a high quality diesel fuel that conforms to ASTM industry specifications. Aftermarket additives can damage the fuel injector system or engine. Use Motorcraft® cetane booster or an equivalent cetane booster additive if you suspect fuel has low cetane. Use Motorcraft® anti-gel & performance improver or an equivalent additive if there is fuel gelling. 17 Super Duty (TFA) , enUSA

Diesel Fuel Additives
It should not be necessary to add any
