engine FORD F350 1999 Repair Manual

5. Follow one of the simple calculations in order to determine fuel
economy:
Multiply liters used by 100, then divide by total kilometers
traveled.
Divide total miles traveled by total gallons used.
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 — 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
•Smooth, moderate operation can yield up to 10% savings in fuel.
•Steady speeds without stopping will usually give the best fuel
economy.
•Idling for long periods of time (greater than one minute) may waste
fuel.
•Anticipate stopping; slowing down may eliminate the need to stop.
•Sudden or hard accelerations may reduce fuel economy.
•Slow down gradually.
•Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
•Revving the engine before turning it off may reduce fuel economy.
•Using the air conditioner or defroster may reduce fuel economy.
•Using 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.
Maintenance and care
200
ProCarManuals.com

•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 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.
•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.
•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
•Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.
Maintenance and care

It is important to note the box in the lower left corner of the window
sticker. These numbers represent the Range of Km/L (MPG) expected on
the vehicle under optimum conditions. Your fuel economy may vary
depending upon the method of operation and conditions.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
•Use only unleaded fuel.
•Avoid running out of fuel.
•Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
•Have the items listed in your Scheduled Maintenance Guide performed
according to the specified schedule.
The scheduled maintenance items listed in the Scheduled Maintenance
Guide are essential to the life and performance of your vehicle and to its
emissions system.
If other than Ford, Motorcraft or Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and durability.
Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats up the engine
compartment and exhaust system, which can start a fire.
Illumination of the charging system warning light, “Service Engine Soon”
light or the temperature warning light, fluid leaks, strange odors, smoke
or loss of oil pressure, could indicate that the emission control system is
not working properly.
Exhaust leaks may result in entry of harmful and potentially
lethal fumes into the passenger compartment.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
Maintenance and care
202
ProCarManuals.com

sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle’s emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal identifies engine displacement and gives some tune up
specifications.
Please consult your “Warranty Guide” for complete emission warranty
information.
Readiness for Inspection/Maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostics system. If your “Check Engine/Service Engine
Soon” light is on, refer to the description in theWarning Lights and
Chimessection of theInstrumentationchapter. Your vehicle may not
pass the I/M test with the “Check Engine/Service Engine Soon” light on.
If the vehicle’s powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a “not ready for I/M test”
condition. To ready the on-board diagnostics system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
•First, at least 10 minutes of driving on an expressway or highway.
•Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
EXTERIOR BULBS

Waxing your vehicle
Wax when water stops beading on the surface. This could be every three
or four months, depending on operating conditions.
Use only carnauba or synthetic-based waxes. Use cleaning fluid or
alcohol with a clean cloth to remove any bugs before waxing vehicle. Use
tar remover to remove any tar spots.
Avoid getting wax on the windshield. If you have wax applied at a
commercial car wash, it is recommended that you clean the wiper blades and
windshield as described inCleaning the wiper blades and windshield.
Repairing paint chips
Minor scratches or paint damage from road debris may be repaired with
the Ultra Touch Prep and Finishing Kit (#F7AZ-19K507–BA), touch-up
paint (#ALBZ-19500–XXXXA), or aerosol paint spray (#ALAZ-19500–
XXXXA) from the Ford Car Care Chemicals line. Please note that the
part numbers (shown as XXXX above) will vary with your vehicle’s
specific coloring. Observe the application instructions on the products.
Remove particles such as bird droppings, tree sap, insect remains, tar
spots, road salt and industrial fallout immediately.
Cleaning the wheels
Wash with the same detergent as the body of your vehicle. Do not use
acid-based or alcohol-based wheel cleaners, steel wool, fuel or strong
detergents. Never use abrasives that will damage the finish of special
wheel surfaces. Use a tar remover to remove grease and tar.
The brushes used in some automatic car washes may damage the finish
on your wheels. Before going to a car wash, find out if the brushes are
abrasive.
Cleaning the engine
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•Take care when using a power washer to clean the engine. The high
pressure fluid could penetrate the sealed parts and cause damage.
•Do not spray with cold water to avoid cracking the engine block or
other engine components.
•Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
