Lincoln Aviator: Maintenance / Engine Oil Check
Engine Oil Dipstick
Engine Oil Check
To check the engine oil level consistently
and accurately, do the following:
- Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N).
- Run the engine until it reaches normal
operating temperature.
- Make sure that your vehicle is on level
ground.
- Switch the engine off and wait 15 minutes
for the oil to drain into the oil pan.
Checking the engine oil level too soon
after you switch the engine off may result
in an inaccurate reading.
- Open the hood.
- Remove the dipstick and wipe it with a
clean, lint-free cloth.
- Reinstall the dipstick and remove it again
to check the oil level.
- Make sure that the oil level is between
the maximum and minimum marks. If the
oil level is at the minimum mark, add oil
immediately.
- If the oil level is correct, replace the
dipstick and make sure it is fully seated.
Note: Do not remove the dipstick when the
engine is running.
Note: If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km).
Adding Engine Oil
WARNING: Do not remove the filler
cap when the engine is running.
Do not use supplemental engine oil additives
because they are unnecessary and could
lead to engine damage that may not be
covered by the vehicle Warranty.
Only use oils certified for gasoline engines
by the American Petroleum Institute (API).
An oil with this trademark symbol conforms
to the current engine and emission system
protection standards and fuel economy
requirements of the International Lubricants
Specification Advisory Committee (ILSAC).
To top up the engine oil level do the
following:
- Clean the area surrounding the engine
oil filler cap before you remove it.
- Remove the engine oil filler cap. Turn
it counterclockwise and remove it.
- Add engine oil that meets our
specifications. You may have
to use a funnel to pour the engine oil into
the opening.
- Recheck the oil level.
- If the oil level is correct, replace the
dipstick and make sure it is fully seated.
- Replace the engine oil filler cap. Turn it
clockwise until you feel a strong
resistance.
Note: Do not add oil further than the
maximum mark. Oil levels above the
maximum mark may cause engine damage.
Note: Make sure you install the oil filler cap
correctly.
Note: Soak up any spillage with an
absorbent cloth immediately.
