CHECKING AND ADDING
ENGINE OIL
Use WSS-M2C153±F motor oil
CERTIFIED FOR GASOLINE
ENGINES by the American
Petroleum Institute.
Engine oils with an SAE 5W-30
viscosity and displaying the
American Petroleum Institute
certification mark are preferred for
your vehicle. They provide the best
engine performance, fuel economy
and engine protection for all
climates down to ±25ÉC (-15ÉF).
Do not use:
²ªnon-detergentº oils
²oils labeled API SA, SB, SC, SD,
SE, SF or SG
²additional engine oil additives,
oil treatments or engine
treatments
Additional engine oil additives, oil
treatments or engine treatments
are never needed and could, under
certain conditions, lead to engine
damage which is not covered by
your Ford warranty.
Synthetic engine oils which are
CERTIFIED and of the preferred
viscosity may be used in your
engine. The engine oil and oil filter
must still be changed according to
the ªService Guideº.
Checking the engine oil
Check the engine oil each time you
fuel your vehicle.
To check the oil:

Maintenance and care

1. Make sure the vehicle is on level
ground. If the engine is warm, turn
the engine off and wait a few
minutes for the oil to drain into
the oil pan.
2. Set the parking brake and
ensure the gearshift is securely
latched in P (Park).
3. Open the hood. Protect yourself
from engine heat.
4. Locate and carefully remove the
engine oil dipstick.
5. Wipe the dipstick clean. Insert
the dipstick fully, then remove it
again. If the oil level falls between
the MIN and MAX markings, there
is no need to refill..
6. If the oil level is below the
minimum line, add engine oil as
necessary. If the oil level is above
the maximum line, engine damage
or high oil consumption may occur
and some oil must be removed
from the engine by a service
technician.
7. Put the dipstick 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 fluid level is not within
the normal range, add only
certified engine oil of the preferred
viscosity. Add engine oil through
the oil filler cap. Remove the filler
cap and use a funnel to pour oil in
the opening.
3. Recheck the oil level. Make sure
the oil level is not above the full
mark on the dipstick.
Your vehicle has an OIL LIFE
LEFT function if you have the
Vehicle Message Center. This
device displays the percent of
useful engine oil life left and when
an oil change is required. Use of a
CERTIFIED oil of the preferred
viscosity is required for this device
to work properly. Change your
engine oil and oil filter when the
Message Center displays CHANGE
OIL SOON or OIL CHANGE
REQUIRED. If the Message Center
malfunctions, you may determine
your oil change interval based on
the following guidelines.
The Vehicle Message Center may
be manually reset by depressing
the Oil Change Reset switch for
five seconds.
Continuous contact with
usedmotor oil has caused
cancer in laboratory mice.
Changing the engine oil and
filter
Change your engine oil and filter
according to the following

kilometers (mileage) and time
requirements, whichever occurs
first:
²Normal Schedule ± 8,000 km
(5,000 miles) or six months.
²Severe Duty Schedule ± 5,000
km (3,000 miles) or three
months. Severe duty operation
would include extensive idling,
trailer towing, driving in severe
dust and police, taxi or delivery
service.
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,
startup 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.
DRIVELINE UNIVERSAL JOINT
AND SLIP YOKE
The universal joints standard with
your vehicle do not require
lubrication. If the original
equipment universal joints are
replaced with universal joints
equipped with grease fittings,
lubrication will be necessary at the
intervals shown in the ªService
Guideº supplement.

CHECKING AND ADDING
BRAKE FLUID
Brake fluid should be checked and
refilled as needed at least once
each year:
²Clean the reservoir cap before
removal to prevent dirt or water
from entering the reservoir.
²Visually inspect the fluid level.
²If necessary, add brake fluid
until the level reaches MAX. Do
not fill above this line.
²Use only a DOT 3 brake fluid
certified to meet Ford
specifications. Refer to
Lubricant specificationsin the
Capacities and specifications
chapter.
Brake fluid is toxic.
If you use a brake fluid
that is not DOT 3, you will
cause permanent damage to your
brakes.
Do not let the reservoir for
the master cylinder run
dry. This may cause the brakes
to fail.
CHECKING AND ADDING
CLUTCH FLUID (IF EQUIPPED)
The clutch on your vehicle is
self-adjusting and should not
require any routine service.
