2003 FORD F350 recommended oil

RWD vehicles with 4x4 electronic shift transfer case or All Wheel
Drive (AWD) vehicles with automatic transmissions:
Regarding recreational towing or having your vehicle towed, 4x4 vehicles
with electronic shift on the fly and AWD vehicles cannot be towed with
any wheels on the ground (with the exception of moving it as a disabled
vehicle off the road out of traffic).
SNOWPLOWING
Note:Do not use your vehicle to snowplow until it has been driven at
least 800 km (500 miles). Follow the severe duty schedule in your
scheduled maintenance guide for engine oil and transmission fluid
change intervals.
Note:Ford does not install snowplows.
For low speed snow removal, Ford offers a Snowplow Package Option on
select 4x4 vehicles. To assist Ford dealers and equipment installers
further prepare the vehicle for snowplowing, Ford includes instructions
in theFord Truck Body Builders Layout BookandFord Truck Source
Book. These instructions are available through your Ford dealer; they
include the list of vehicle models recommended for snowplowing and
snowplow weight limits. Use of the Snowplow Package Option, or its
equivalent, along with these instructions will help avoid possible
powertrain and chassis damage from snowplowing.
The front and rear GAWR, GVWR, Total Accessory Reserve Capacity
(TARC) and tire inflation pressures are found on the Safety Compliance
Certification Label located on one of the vehicle’s door jambs. This label
is applied to all vehicles completed by Ford Motor Company. Incomplete
vehicles built by Ford Motor Company will have an Incomplete Vehicle
Label in place of the Safety Compliance Label. The TARC does not apply
to Incomplete Vehicles and will not be shown on the Incomplete Vehicle
Label. The weight of the vehicle with occupants must never exceed the
front and rear GAWR or the GVWR.
The TARC is the weight of the permanently attached equipment that can
be added to the vehicle without violating the vehicle’s Safety Compliance
Certification. This includes the snowplow mounting hardware but does
not include the removable portion of the snowplow assembly.
Installing the snowplow
Read the following instructions before installing a snowplow:
•Front GAWR must not exceed 63% of the GVW. Add ballast weight to
the back of the vehicle, if necessary. Refer to the Safety Compliance
Certification Label to find your vehicle’s front GAWR.

5. Locate and carefully remove the
engine oil level indicator (dipstick).
6. Wipe the indicator clean. Insert the indicator fully, then remove it
again.
•If the oil level isbetween the MIN and MAX marks,the oil level is
acceptable.DO NOT ADD OIL.
•If the oil level is below the MIN
mark, add enough oil to raise the
level within the MIN-MAX range.
•Oil levels above the MAX mark may cause engine damage. Some oil
must be removed from the engine by a service technician.
7. Put the indicator back in and ensure it is fully seated.
Adding engine oil
1. Check the engine oil. For instructions, refer toChecking the engine
oilin this chapter.
2. If the engine oil level is not within the normal range, add only certified
engine oil of the recommended viscosity. Remove the engine oil filler cap
and use a funnel to pour the engine oil into the opening.

3. Recheck the engine oil level. Make sure the oil level is not above the
MAX mark on the engine oil level indicator (dipstick).
4. Install the indicator and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap clockwise
1/4 of a turn until three clicks are heard or until the cap is fully seated.
To avoid possible oil loss, DO NOT operate the vehicle with the
engine oil level indicator and/or the engine oil filler cap removed.
Engine oil and filter recommendations
Look for this certification
trademark.
SAE 5W-20 engine oil is recommended.
Only use oils“Certified For Gasoline Engines”by the American
Petroleum Institute (API). Use Motorcraft or an equivalent oil meeting
Ford specification WSS-M2C153–H.SAE 5W-20 oil provides optimum
fuel economy and durability performance meeting all
requirements for your vehicle’s engine.
Do not use supplemental engine oil additives, oil treatments or engine
treatments. They are unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your warranty.
Change your engine oil and filter according to the appropriate schedule
listed in the scheduled maintenance guide.
Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, start-up
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.

•Revving the engine before turning it off may reduce fuel economy.
•Using the air conditioner or defroster may reduce fuel economy.
•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•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 specificationsin
this chapter.
•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
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/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.
