Maintenance; Conditions - Ford 1998 Mustang Owner's Manual

Maintenance and care
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.
Use of 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.
Flat terrain driving improves fuel economy over
hilly roads.
Transmissions give their best fuel economy when
operated in the top cruise gear and with steady
pressure on the gas pedal.
Close windows for high speed driving.
