Maintenance and Specifications Biodiesel use may affect the recommended oil change intervals. Refer to the Special Operating Conditions section in the schedule maintenance guide for more information about oil change intervals and other maintenance when operating on biodiesel. Biodiesel fuel is a product that has been converted from renewable fuel sources, including vegetable oil, animal fat and cooking oil. Raw or refined vegetable oil, animal fat, cooking oil or recycled greases should not be used. Do not use home heating oil, agricultural fuel 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. FUEL REQUIREMENTS - CHOOSING THE RIGHT FUEL: VEHICLES OPERATED WHERE ULTRA LOW SULFUR DIESEL FUEL IS NOT REQUIRED For a 6.4L engine to operate reliably on low sulfur or high sulfur diesel fuel, the 6.4L engine must be a high sulfur configured engine or a ULSD fuel-configured engine that has been retrofitted for high sulfur diesel fuel use. Use only a 6.4L diesel engine that has been configured for use with high sulfur diesel fuel in markets with diesel fuel that has sulfur content greater than 15 ppm. Using low sulfur diesel fuel (16-500 ppm) or high sulfur diesel fuel (greater than 500 ppm) in a 6.4L diesel engine designed to use only Ultra Low Sulfur Diesel fuel increases the likelihood of engine oil dilution with fuel which may lead to major engine damage. Engine damage from using the improper type of fuel is not covered under your warranty. Vehicles with 6.4L engines configured for use with high sulfur diesel fuel will only be made available for sale in countries where ULSD fuel is not available or mandated by the government. Vehicles originally sold in a ULSD fuel market that are subsequently exported to non-ULSD fuel markets will need to be retrofitted (at the customer's expense) in order to be reliably operated on non-ULSD fuel. Vehicles equipped with a 6.0L engine that are operated in a market that does not require ULSD fuel may be operated on higher sulfur fuel without any engine fuel system or emissions-related concerns. Number 1-D or winter blend number 2-D fuel is recommended at temperatures below 20°F (-7°C) (see Cold weather operation in the 35
