engine oil FORD MUSTANG 2004 4.G User Guide

•If the oil level is below the MIN mark, add enough
oil to raise the level within the MIN—MAX range.
•OHV V6 engine
•4.6L SOHC V8 engine
•4.6L 4v V8 engine
(Mach 1)
•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 to
Checking 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.
Use SAE 5W-20 engine oil.
Only use oils“Certified For Gasoline Engines”by the
American Petroleum Institute (API). To protect your
engine’s warranty use Motorcraft SAE 5W-20 or an
equivalent 5W-20 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,
cleaners or other engine treatments. They are

unnecessary and could lead to engine damage that is
not covered by Ford warranty.
Change your engine oil 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.
BATTERY
Your vehicle is
equipped with a
Motorcraft
maintenance-free
battery which normally
does not require
additional water during
its life of service.
However, for severe usage or in high temperature
climates, check the battery electrolyte level. Refer to
the scheduled maintenance guide for the service
interval schedules.
Keep the electrolyte level in each cell up to the
“level indicator”. Do not overfill the battery
cells.
If the electrolyte level in the battery is low, you can
add plain tap water to the battery, as long as you do
not use hard water (water with a high mineral or
alkali content). If possible, however, try to only fill
the battery cells with distilled water. If the battery
needs water often, have the charging system
checked.
If your battery has a cover/shield, make sure it
is reinstalled after the battery has been
cleaned or replaced.

•Always dispose of
automotive batteries
in a responsible
manner. Follow your
local authorized
standards for
disposal. Call your
local authorized
recycling center to find out more about recycling
automotive batteries.
ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should
be checked at the mileage intervals in the scheduled
maintenance guide. The coolant concentration
should be maintained at 50/50 coolant and water,
which equates to a freeze point of -36°C (-34°F).
Coolant concentration testing is possible with a
hydrometer or antifreeze tester (such as the
Rotunda Battery and Antifreeze Tester, 014–R1060).
The level of coolant should be maintained at the
“cold full”of“cold fill range”level in the coolant
reservoir. If the level falls below, add coolant per the
instructions in theAdding Engine Coolantsection.
Your vehicle was factory-filled with a 50/50 engine
coolant and water concentration. If the
concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not
work properly.A50–50 mixture of coolant and
water provides the following:
•freeze protection down to -36°C (-34°F)
•boiling protection up to 129°C (265°F)
•protection against rust and other forms of
corrosion
•enables calibrated gages to function properly

•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.
•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).

4Indicates only approximate dry-fill capacity. Some
applications may vary based on cooler size and if
equipped with an in-tank cooler. The amount of
transmission fluid and fluid level should be set by
the indication on the dipstick’s normal operating
range.
5Service refill capacity is determined by filling the
transmission to the bottom of the filler hole with the
vehicle on a level surface.
6Use of synthetic or synthetic blend motor oil is not
mandatory. Engine oil need only meet the
requirements of Ford specification WSS-M2C153–H
and the API Certification mark.
