•Revving the engine before turning it off may reduce fuel economy.
•Using the air conditioner or defroster may reduce fuel economy.
•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toLubricant specificationsin
this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found inscheduled maintenance information.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Using fuel blended with alcohol may lower fuel economy.
•Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.

meeting Ford specification EST-M2C118–A, for complete refill of 8.8 inch
and 9.75 inch Traction-Lok axles.
3Fill Dana rear axles to 1/4 inch to 9/16 inch (6 mm to 14 mm) below
bottom of fill hole. Fill Visteon axles 1/4 inch to 9/16 inch (6 mm to 14
mm) below bottom of fill hole.
4Visteon Traction-Lok axles require 4 oz. (118 ml) of Additive Friction
Modifier XL–3 or equivalent. Dana limited-slip axles (E250/350/450/550)
require 8 oz. (237ml) of Additive Friction Modifier XL–3 or equivalent
meeting Ford specification EST-M2C118-A.
5Optional fuel tank 55 gallon (208 L).
6Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on the dipstick or on the dipstick
handle. Check the container to verify the fluid being added is of the
correct type. Refer to yourscheduled maintenance informationto
determine the correct service interval.
Some transmission fluids may be labeled as dual usage, such as
MERCONand MERCONV. These dual usage fluids are not to be used
in an automatic transmission that requires use of the MERCONtype
fluid. However, these dual usage fluids may be used in transmissions that
require the MERCONV type fluid.
MERCON, MERCONV and MERCONSP are not
interchangeable. DO NOT mix MERCON, MERCONV and
MERCONSP. Use of dual usage fluids in an automatic
transmission application requiring MERCONSP may cause
transmission damage. Use of a transmission fluid other than the
recommended fluid may cause transmission damage.
7Indicates only approximate dry-fill capacity. Some applications may vary
based on cooler size, if equipped with an in-tank cooler, if equipped an
oil to air cooler and if equipped with a remote filter assembly. The
amount of transmission fluid and fluid level should be set by the
indication on the dipstick’s normal operating range.
8Use of synthetic or synthetic blend motor oil is not mandatory. Engine
oil need only meet the requirements of Ford specification
WSS-M2C930-A and the API Certification mark.
