than 5% biodiesel may be used. Use of biodiesel in concentrations
greater than 5% may cause damage to your vehicles fuel system
components such as fuel tank, fuel lines, fuel pump, fuel sender and fuel
injectors. Concentrations greater than 5% can also cause fuel filter
restrictions that may result in a lack of power and or fuel pump and fuel
injector failure.
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 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) (seeCold weather operationin the
Drivingchapter of this supplement). Diesel fuel containing no more
than 5% biodiesel may be used. Use of biodiesel in concentrations
greater than 5% may cause damage to your vehicles fuel system
