Keep a record for at least one month and record the type of driving (city
or highway). This will provide an accurate estimate of the vehicle's fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter will show how temperature impacts fuel
economy. In general, lower temperatures give lower fuel economy.
Driving style Ð good driving and fuel economy habits
Give consideration to the lists that follow and you may be able to change
a number of variables and improve your fuel economy.
Habits
²Smooth, moderate operation can yield up to 10% savings in fuel.
²Steady speeds without stopping will usually give the best fuel
economy.
²Anticipate stopping; slowing down may eliminate the need to stop.
²Sudden or hard accelerations may reduce fuel economy.
²Slow down gradually.
²Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
²Using the air conditioner or defroster may reduce fuel economy.
²Resting your foot on the brake pedal while driving may reduce fuel
economy.
Conditions
²Carrying unnecessary weight may reduce fuel economy.
²Fuel economy may decrease with lower temperatures during the first
12±16 km (8±10 miles) of driving.
²Flat terrain driving improves fuel economy over hilly roads.
²Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the accelerator.
²Close windows for highway driving.
FUEL CONSUMPTION IMPROVEMENT MEASURES
There are two important factors you can control to improve fuel
economy: the mechanical condition of your vehicle and how you drive it.
A properly maintained vehicle will deliver better performance than a
neglected vehicle. Always follow your maintenance schedule to keep your
vehicle in top operating condition.

intervals are as
follows: Powerstroke -
10 000 ; Caterpillar -
15 000 ; Cummins - 15
000 (refer to the
Caterpillar and
Cummins service
manuals for further
instructions and
information)Fuel system
Drain the accumulated water or sediment from
the fuel tank(s)
Steering system
Lubricate the steering shaft(s), U-joints and
splines when equipped with grease fittings
Lubricate the front axle spindle pins
Lubricate the steering linkage when equipped
with grease fittings
Grease the power steering gear output shaft
* Coolant protection checks should be made just prior to the onset of
freezing weather, where applicable. If coolant is dirty or rusty in
appearance, the system should be drained, flushed and refilled with the
prescribed solution of cooling system fluid and water. Use only
permanent type coolant that meets Ford specifications ESE-M97B18-C.
See the engine manufacturer's operating guide for supplimental
corrosion inhibitor specifications.
In addition to the items to be performed daily or at each oil change, the
following need to be completed as specified:
8 000KM / 5 000 MILES
²Initial change Ð change the lubricant in the manual shift transmission
± 5 speed and 6 speed Eaton manual transmission. (Not required
when equipped with optional synthetic lubricant.)
32 000 KM / 20 000 MILES
²Replace the fuel filter.*
50 000 KM / 30 000 MILES
²Replace the engine spin-on coolant filter.*
²Repack and adjust the front wheel bearings Ð grease-filled hubs.
65 000 KM / 40 000 MILES
²Replace the fuel filter.*
