•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 in your vehicle scheduled maintenance guide.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] 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
12–16 km (8–10 miles) 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.

1Add 236 ml (8 oz.) of Additive Friction Modifier XL-3 or equivalent
meeting Ford specification EST-M2C118-A for complete refill of
Traction-Lok axles. Ford design rear axles contain a synthetic lubricant
that does not require changing unless the axle has been submerged in
water.
2Ensure 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 your scheduled maintenance guide to 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.
MERCONand MERCONV type fluids are not interchangeable.
DO NOT mix MERCONand MERCONV. Use of a transmission
fluid that indicates dual usage (MERCONand MERCONV) in
an automatic transmission application requiring MERCONmay
cause transmission damage. Use of any fluid other than the
recommended fluid may cause transmission damage.
