FORD 1999 F-150 - Manual (Page 201)

• Drive at reasonable speeds (traveling at 105 km /h [65 mph] uses 15%
more fuel than traveling at 88 km/h [55 mph]).
• Revving the engine before turning it off may reduce fuel economy.
• Use of the air conditioner or defroster may reduce fuel economy.
• Use of speed control (if equipped) may improve fuel economy. Speed
control can help maintain a constant speed and reduce speed changes.
You may want to turn off the speed control in hilly terrain as
unnecessary shifting between third and fourth gears may occur and
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 to Lubricant Specifications.
• 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
2 km/h [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
• Adding certain accessories to your vehicle (for example bug
deflectors, rollover/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
• To maximize the fuel economy, drive with the tonneau cover installed
(if equipped).
• Use of fuel blended with alcohol may lower fuel economy.
