Diesel fuel is adjusted seasonally for cold
temperature. For best results at
temperatures below 19°F (-7°C), we
recommend using a diesel fuel which has
been seasonally adjusted for the ambient
conditions.
Choosing the Right Fuel: Vehicles
Operated Where Ultra Low Sulfur
Diesel Fuel Is Not Required
For the engine to operate reliably on
low-sulfur or high-sulfur diesel fuel, the
engine must be a factory-built high-sulfur
engine (available as a dealer order option
for select markets) or an ultra-low sulfur
diesel fuel configured engine that has been
retrofitted for high-sulfur diesel fuel using
authorized dealer service parts. Failure to
use retrofit components other than those
available through your authorized dealer
results in coolant system damage, engine
overheating, selective catalyst reduction
system or diesel particulate filter damage
and possible base engine damage.
Use only a diesel engine 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 diesel engine
designed to use only ultra-low sulfur diesel
fuel could result in damage to engine
emission control devices and the after
treatment system, potentially rendering
the vehicle inoperable.
Vehicles with engines configured for use
with high-sulfur diesel fuel are only
available for sale in countries where
ultra-low sulfur diesel fuel is generally not
available or mandated by the government.
Vehicles originally sold in an ultra-low
sulfur diesel fuel market that are

Fuel and Refueling
subsequently exported to non-ultra low
sulfur diesel fuel markets will need to be
retrofitted at the customer's expense using
Ford authorized dealer service parts in
order to be reliably operated on non-ultra
low sulfur diesel fuel.
Biodiesel
gasoline, gasohol or alcohol. This could
cause an explosion.
Note: Do not use home heating oil,
agricultural fuel, raw fats and oils, waste
cooking greases, biodiesel greater than 20%
or any diesel not intended for highway use.
Damage to the fuel injection system, engine
and exhaust catalyst, and diesel particulate
filter can occur if you use an improper fuel.
Red dye is used to identify fuels intended
for agricultural and non-highway use.
You can operate your vehicle on diesel
fuels containing up to 20% biodiesel, also
known as B20.
Biodiesel fuel is a chemically converted
product from renewable fuel sources, such
as vegetable oils, animal fats and waste
cooking greases.
To help achieve acceptable engine
performance and durability when using
biodiesel in your vehicle:

WARNING: Do not mix diesel with
Confirm the biodiesel content of the
fuel to be B20 (20% biodiesel) or less.
Only use biodiesel fuel of good quality
that complies with industry standards.
Follow the recommended service
maintenance intervals. See General
Maintenance Information (page 589).
