Fuel and Refueling DIESEL FUEL ADDITIVES It should not be necessary to add any aftermarket additives to your fuel tank if you use a properly formulated diesel fuel. Aftermarket additives can damage the 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. 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/system. refer to the Technical specifications section in the Capacities and Specifications chapter for more information. Repairs to correct the effects of using an aftermarket product that does not meet Ford specifications in your fuel may not be covered by your warranty. Note: Ultra Low Sulfur Diesel fuel is designed to meet the emissions standards for the 6.7L engine and is backward compatible as well (i.e., can be used in Ford 7.3L, 6.9L, 6.4L and 6.0L diesel engines in Ford vehicles). FUELING TIPS WARNING: Do not use starting fluid such as ether or gasoline in the diesel air intake system. Such fluids can cause immediate explosive damage to the engine and possible personal injury. Truck stops have pumps and nozzles designed for larger, heavy-duty trucks. When refueling at truck stops: if the nozzle shuts off repeatedly when refueling, wait 5-10 seconds; then use a slower rate of flow (don't depress the nozzle trigger as far). If air is allowed to enter the fuel system (during fuel filter change or if you run out of fuel) the engine will purge the trapped air as it runs. To purge the air sooner: prior to engine start, prime the system by turning the key to on for 30 seconds then to off. Repeat this several times. The engine may run rough and produce white smoke while air is in the system. This is normal and should correct itself in a short time. An engine that suddenly becomes noisy or operates poorly after a fuel fill could be using substandard fuel (i.e., high water content, low cetane rating or gasoline in the fuel). Diesel fuel should be purchased from a reputable station which sells a large amount of diesel fuel. 17 2013 Diesel (67l) Supplement, 1st Printing USA (fus)
