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). An oil with this trademark symbol conforms
to the current engine and emission system protection standards and fuel
economy requirements of the International Lubricant Standardization and
Approval Committee (ILSAC), comprised of U.S. and Japanese
automobile manufacturers.
To protect your engine and engine’s warranty, use Motorcraft SAE 5W-20
or an equivalent SAE 5W-20 oil meeting Ford specification
WSS-M2C930-A.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 and filter according to the appropriate schedule
listed in thescheduled maintenance information.
Ford production and Motorcraft replacement 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 with equivalent performance for your engine application.

Changing the air filter element
1. Release the clamps that secure
the air filter housing cover.
2. Carefully separate the two halves
of the air filter housing.
3. Remove the air filter element
from the air filter housing.
4. Wipe the air filter housing and
cover clean to remove any dirt or
debris and to ensure good sealing.
5. Install a new air filter element. Be
careful not to crimp the filter element edges between the air filter
housing and cover. This could cause filter damage and allow unfiltered
air to enter the engine if not properly seated.
6. Replace the air filter housing
cover and secure the clamps. Be
sure that the air cleaner cover tabs
are engaged into the slots of the air
cleaner housing.
Note:Failure to use the correct air filter element may result in severe
engine damage. The customer warranty may be void for any damage to
the engine if the correct air filter element is not used.
