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:

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:
1. Make sure the vehicle is on level
ground. If the engine is running,
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.
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. The oil level should be in
the range shown on the dipstick.
6. If the oil level is below the
minimum line, add engine oil as
necessary. If the oil level is beyond
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.
