Maintenance and Specifications Fuel quality It should not be necessary to add any aftermarket additives to your fuel tank if you use a properly formulated diesel fuel that meets either the ASTM D975 diesel or the ASTM D7467 B6-B20 biodiesel industry specifications. Outside of North America, use fuels meeting EN590 or equivalent local market standard. Aftermarket additives can damage the injector system or engine. Repairs to correct the effects of using an aftermarket product in your fuel may not be covered by your warranty. Many of the world's automakers approved the World-wide Fuel Charter that recommends diesel fuel specifications to provide improved performance and emission control system protection for your vehicle. Diesel fuel that meets the World-wide Fuel Charter should be used when available. Ask your fuel supplier about fuel that meets the World-wide Fuel Charter. 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. Diesel fuel conditioner Additives that will improve fuel cetane numbers may be used to verify/enhance fuel quality. Use Motorcraft or an equivalent cetane booster & performance improver as listed in the Maintenance product specifications and capacities section in this chapter. The customer warranty may be void from using additives that do not meet or exceed Ford specifications. Do not use alcohol based additives to correct fuel gelling. This may result in damage to the fuel injectors/system. Use Motorcraft or an equivalent anti-gel & performance improver as listed in the Maintenance product specifications and capacities section in this chapter. The customer warranty may be void from using additives that do not meet or exceed Ford specifications. Note: These ultra-low sulfur formulations are 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 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). 24 2011 Diesel (eco) Supplement, 5th Printing USA (fus)
