Changing the engine oil and
filter
Change your engine oil and filter
according to the following mileage
and time requirements, whichever
occurs first:
²Normal Schedule ± 8,000 km
(5,000 miles) or six months.
²Severe Duty Schedule - 5,000
km (3,000 miles) or three

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.

It should not be necessary to add
any aftermarket products to your
fuel tank if you continue to use a
high-quality fuel.
Cleaner air
Ford approves the use of gasolines
to improve air quality, including
reformulated gasolines that contain
oxygenates up to 10% ethanol or
15% MTBE.
Do not use gasolines containing
methanol, which can damage
critical fuel system components.
Damage resulting from the use of
methanol may not be covered by
your warranty.
Calculating fuel economy
To accurately calculate your
vehicle's fuel economy:
1. Fill the tank completely and
record the initial odometer
reading.
2. Each time you fill the tank,
record the amount of fuel added
(in liters or gallons).
3. After at least three to five fuel
tank fill-ups, fill the fuel tank and
record the current mileage
reading.
4. Use one of the following
equations to calculate fuel
economy.
