fuel consumption FORD F750 2005 11.G Owners Manual

Vehicles that are equipped with an
override feature, allow the operator
to restart the engine so the vehicle
can be moved; the engine should
not be operated any longer than
necessary. A decal located in front
of the operator provides instructions
on how the override should be
operated.
Do not attempt to use this restarting feature to drive the vehicle very far
as serious engine damage could result.
In the event of engine shutdown, make sure the vehicle is safely
off the road and the problem is remedied prior to returning to
the road. Failure to remove the vehicle from the road could result in
an accident, causing serious injury or death.
GENERAL OPERATING INSTRUCTIONS
•Start the vehicle in motion by using the highest gear speed in the
transmission that will let the engine easily start the load without
slipping the clutch.
•Accelerate smoothly and evenly; rapid acceleration increases fuel
consumption without increasing engine performance.
•When approaching a hill, depress the accelerator smoothly to start the
incline at full power, then shift down as needed to maintain vehicle
speed.
•When going down a hill, or long steep grades, prevent over-speeding
of the engine. The engine governor has no control over engine speed
when it is being pushed by a loaded vehicle.
•Operate in a gear that will permit an engine speed not in excess of the
maximum governed speed or high-idle RPM (no load).
•Normally, choose the same gear to descend the hill that you would use
to ascend the hill.
All vehicles have blind spots. To reduce the risk of severe injury
or property damage, never move your vehicle to the side or rear
or change lanes without being sure your way is clear on both sides and
to your rear.

2. Remove and discard the old fuel
filter element.
3. Carefully clean the mating
surfaces.
Installation-both
The engine will not run properly if the fuel filter is not installed
in housing.
1. Install new fuel filter into the fuel filter housing.
2. Tighten cap onto fuel filter housing slowly, allowing fuel to soak into
the fuel filter element. Tighten cap until it contacts the housing.
After replacing the fuel filter, the engine will purge the trapped
air as it runs. The engine may run roughly and smoke until the air
is completely eliminated.
Using a fuel which has more than average impurities may require
the fuel filter to be replaced more frequently than the service
interval specifies.

Refer to your engine operator’s manual for service intervals and
procedures.
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.
