Scheduled Maintenance; Fuel Requirements - Ford Diesel 2011 Supplement Manual

Maintenance and Specifications

SCHEDULED MAINTENANCE

The scheduled maintenance services in the scheduled maintenance
information of this supplement are required because they are
considered essential to the life and performance of your vehicle.
Use only recommended fuel, lubricants, fluids and service parts
conforming to Ford specifications. Motorcraft parts are designed and
built for best performance in your vehicle.
FUEL REQUIREMENTS - CHOOSING THE RIGHT FUEL: VEHICLES
OPERATED WHERE ULTRA LOW SULFUR DIESEL FUEL IS
REQUIRED (UNITED STATES/CANADA/PUERTO RICO/U.S. VIRGIN
ISLANDS AND OTHER LOCALES)
Use only Ultra Low Sulfur (15 ppm Sulfur Maximum) number 1-D
or 2-D diesel fuel (also known as ULSD) in your 6.7L diesel
engine. The engine and exhaust system were designed to only use this
fuel. Look for the ULTRA-LOW SULFUR HIGHWAY DIESEL FUEL
(15 ppm Sulfur Maximum) label on fuel pumps when purchasing your
fuel.
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 will cause certain emission
components to malfunction which may also cause the service
engine soon light to illuminate indicating an emissions-
related concern.
Diesel fuel is adjusted seasonally for cold temperature. For best results
at temperatures below 20°F (-7°C), it is recommended to use a diesel
fuel which has been seasonally adjusted for the ambient conditions. See
Cold weather operation in the Driving chapter of this supplement.
FUEL REQUIREMENTS - 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 high sulfur configured engine or a ULSD
fuel-configured engine that has been retrofitted for high sulfur diesel fuel
use.
