2002 FORD F750 oil temperature

Using the chart, determine which SAE viscosity grade best suits the
temperature range in which you expect to operate your vehicle. The use
of the correct oil viscosity grade for diesel engines is important for
satisfactory engine operation.
A symbol has been developed by the American Petroleum Institute (API)
to help you select the proper engine oil. The symbol will be included on
the oil container you purchase.
The top section of the symbol shows
the API service category
designation. This should be CH-4/SJ.
The center section of the API
symbol shows the SAE viscosity
grade.
The lower section of the API symbol
will stateenergy conservingif the
engine oil has been proven to have fuel savings capabilities.
Use a Ford engine oil filter, part number FL-1995 or equivalent. This
filter protects your engine by filtering harmful, abrasive or sludge
particles.

²Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
If you must replace the fuel filler cap, replace it with a genuine
Ford or Motorcraft part. The customer warranty may be void for
any damage to the fuel tank or fuel system if a genuine Ford or
Motorcraft fuel filler cap is not used.
If you do not use the proper fuel filler cap, excessive pressure or
vacuum in the fuel tank may damage the fuel system or cause
the fuel system to work improperly in a collision, which may result in
possible personal injury.
Choosing the right fuel
At operating temperatures below 0ÉC (32ÉF), use a blend of No. 1D and
No. 2D Diesel fuels, also known as winterized No. 2D.
Do not use diesel fuel blended with waste oil in engines equipped with a
catalytic converter-muffler. Blending waste oil in with the fuel will plug
the catalytic converter-muffler, resulting in a significant loss of engine
power. Your emissions warranty will be voided if blending waste oil with
diesel fuel is practiced.
Use low sulfur (less than 0.05% by weight) fuel as required by the EPA
for emission compliance.
Do not mix diesel fuel with gasoline, gasohol or alcohol. This
could cause an explosion resulting in personal injury.
Do not use starting fluid such as ether or gasoline. Such fluids
can cause immediate explosive damage to the engine and
possible personal injury.

OWNER MAINTENANCE
You can do much of the maintenance your vehicle requires yourself, if
you have the time and a reasonable amount of mechanical ability. If you
prefer to have this work done professionally, your authorized dealer
stands ready to help you.
All mechanical components and attachments are important in that they
could affect the performance of vital components and systems. If
replacement becomes necessary, they must be replaced with parts having
the same part number or with equivalent parts. Torque values of the
attaching parts must be used as specified during any reassembly
procedure to assure proper retention.
EMISSIONS CONTROL SYSTEM
To assure the emissions control systems operate effectively, you should
have the services listed in the maintenance schedule performed at the
specified time and km/mileage intervals. You should avoid running out of
fuel or turning off the ignition while the vehicle is in motion, especially
at high speeds.
Because of high engine compartment and exhaust system
temperatures resulting from emissions equipment, do not park,
idle or operate your vehicle in dry grass or other dry ground cover
where the possibility of ground fire exists.
Do not make unauthorized modifications to the engine or vehicle.
Modifications causing increased amounts of unburned fuel to reach the
exhaust system can significantly increase the temperature of the engine
compartment and/or the exhaust system.
Avoid driving your vehicle if it does not operate properly. If the engine
diesels (more than five seconds of engine run-on after shut-off), misfires,
surges, stalls or backfires, see your dealer. Be alert for fluid leakage,
odor, smoke, loss of oil pressure, or charge indicator or over temperature
warning.
Do NOT use diesel fuel blended with waste oil in engines equipped with
a CATALYTIC CONVERTER-MUFFLER. Waste lube oil blending in fuel
will plug the CATALYTIC CONVERTER-MUFFLER, resulting in a
significant loss of engine power.

scheduled intervals because they are considered essential to the life and
performance of your vehicle. Ford recommends that you perform
maintenance on all designated items to achieve best vehicle operation.
Scheduled maintenance beyond 160 930 km (100 000 miles) should be
continued as before 160 930 km (100 000 miles).
SPECIAL OPERATING CONDITIONS
If your driving habitsfrequentlyinclude one or more the following
conditions:
²Short trips oflessthan 16 km (ten miles) when outside temperatures
remain below freezing.
²Operating duringhot weatherin stop-and-go ªrush hourº traffic.
²Operating in severe dust conditions.
²Extensive idling, or low speed operation such as door-to-door delivery
service.
²High speed operation with a fully loaded vehicle (max. GVW).
²Snowplowing.
Perform the following:
²Change engine oil and oil filter every three months, 8 000 km (5 000
miles) or 125 hours of engine service.
²If operating in severe dust conditions, replace the air cleaner filter
more often than regular intervals as determined by the air filter
restriction indicator. Make sure that the air filter restriction indicator
is in good working order.
²Lube the manual transmission and the rear axle every 48 279 km
(30 000 miles) or 6 months, whichever comes first.
²See the Allison, Cummins and Caterpillar Operator's Manual.
AIR BRAKE ADJUSTMENT
Failure to maintain proper air brake adjustment can result in
reduction or loss of braking ability.
Air brake inspection and adjustment should be performed by a qualified
service technician in accordance with the instructions in the Ford Truck
Service Manual.
