Engine oil and filter recommendations
Look for this
Certification
Trademark.
Use SAE 5W-30 motor oil certified for gasoline
engines by the American Petroleum Institute (API).
Motor oil displaying the API Certification Trademark
will meet all requirements for your vehicle's engine.
Ford oil specification is WSS-M2C153-G.
Do not use supplemental engine oil additives, oil
treatments or engine treatments. They are
unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your
warranty.
Change your engine oil and filter according to the
appropriate schedule listed in the Scheduled
Maintenance Guide.
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.
BRAKE FLUID
Checking and adding brake fluid
Brake fluid should be checked and refilled as
needed. Refer to the Scheduled Maintenance Guide
for the service interval schedules:
