Checking and Adding Engine Oil
*
[MC07100(FM)01/96]
Since the proper amount of engine oil is
important for safe engine operation, check the oil
using the dipstick each time you put fuel in
your vehicle. Remember the engine must be off,
the oil must be warm and the vehicle must be
parked on level ground.

[MC07200(FM)01/96]
Checking the engine oil level:
*
[MC07300(FM)01/96]
1. Turn the engine off after it has warmed up
and allow a few minutes for the engine oil
to drain back into the oil pan.
*
[MC07400(F )01/96]
2. Set the parking brake, making sure that the
gearshift is securely latched in P (Park)
(automatic transmission) or 1 (First) (manual
transmission).
*
[MC07600(FM)01/96]
3. Open the hood. Protect yourself from engine
heat.
*
[MC07700(FM)01/96]
4. Locate the engine oil dipstick (highlighted in

6. Carefully, pull the dipstick out again. If the
oil level is below the ªADD 1 QT.º line, add
engine oil as necessary. If the oil level is
beyond the letter ªFº in FULL, engine
damage or high oil consumption may occur
and some oil must be removed from the
engine.

7. Put the dipstick back in and make sure it is

[MC08200(FM)01/96]
It may be necessary to add some oil between oil
changes. Make sure you use a CERTIFIED
engine oil of the preferred viscosity. Your
vehicle's warranty coverage may not apply if
engine damage is caused by the use of improper
engine oil.
*
[MC08300(FM)01/96]
Add engine oil through the oil filler cap
highlighted in yellow. To add oil, remove the
filler cap and use a funnel to pour oil into the
opening. Be careful not to overfill the engine.
Recheck the oil level after you finish adding oil.

Changing the Engine Oil and the Oil Filter

Oil change intervals
[MC08800(FM)04/96]
NOTE: Idling the engine for extended periods
will accumulate more hours of use on
your vehicles than is actually indicated
by the mileage odometer.
Consequently, the odometer reading
can be often misleading when
determining the right time to change
your engine oil and filter.
[MC08900(F )04/96]
If you are using your Ford vehicle in a manner
which allows it to remain stationary while the
engine is running for long periods (door to
door delivery, taxi, police, power/utility
company trucks, or similar duty), then Ford
recommends you increase the frequency of oil
and filter changes to an interval equivalent to
200 ENGINE HOURS of use. Since most
vehicles are not equipped with hourmeters, it
may be necessary for you to approximate your
idle time and plan oil/filter changes
accordingly.
