FUEL QUALITY
Selecting the Correct Fuel
Your vehicle operates on regular unleaded
gasoline with a minimum pump (R+M)/2
octane rating of 87.
Some fuel stations, particularly those in high
altitude areas, offer fuels posted as regular
unleaded gasoline with an octane rating
below 87. The use of these fuels could result
in engine damage that will not be covered
by the vehicle Warranty. For best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather as well as
other conditions, for example when towing
a trailer. See Towing a Trailer (page 299).
Do not be concerned if the engine
sometimes knocks lightly. However, if the
engine knocks heavily while using fuel with
the recommended octane rating, contact an
authorized dealer to prevent any engine
damage.
We recommend Top Tier detergent
gasolines, where available to help minimize
engine deposits and maintain optimal vehicle
and engine performance.

Note: Use of any fuel for which the vehicle
was not designed can impair the emission
control system, cause loss of vehicle
performance, and cause damage to the
engine which may not be covered by the
vehicle Warranty. Do not use:
•
Diesel fuel.
• Fuels containing kerosene or paraffin.
• Fuel containing more than 15% ethanol
or E85 fuel.
• Fuels containing methanol.
• Fuels containing metallic-based additives,
including manganese-based compounds.
• Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Leaded fuel, using leaded fuel is
prohibited by law.
The use of fuels with metallic compounds
such as methylcyclopentadienyl manganese
tricarbonyl, which is a manganese-based fuel
additive, will impair engine performance and
affect the emission control system.

ENGINE OIL CAPACITY AND
SPECIFICATION - 2.0L
Use oil that meets the defined specification
and viscosity grade.
If you do not use oil that meets the defined
specification and viscosity grade, it could
result in:
•
Component damage that your vehicle
warranty does not cover.
• Longer engine cranking periods.
• Increased emission levels. •
Reduced vehicle performance.
• Reduced fuel economy. An oil that displays this symbol conforms to
current engine, emission system and fuel
economy performance standards of ILSAC.
We recommend Motorcraft motor oil for your
vehicle. If Motorcraft oil is not available, use
motor oils of the recommended viscosity
grade that meet API SP requirements and
display the API Certification Mark for gasoline
engines.
Do not use supplemental engine oil additives
because they are unnecessary and could
lead to engine damage that your vehicle
warranty does not cover.

If your information display resets prematurely
or becomes inoperative, you should perform
the oil change interval at six months or
5,000 mi (8,000 km) from your last oil
change. Never exceed one year or 10,000 mi
(16,000 km)
between oil change intervals.
You can drive high performance vehicles in
such a way that may lead to higher oil
consumption including extended time at high
engine speeds, high loads, engine braking,
hard cornering maneuvers, track and off-road
usage. Under these conditions, oil
consumption of approximately 1 quart per
500 miles (1 liter per 800 km) is possible.
Check the engine oil level at every refueling
and adjust to maintain proper levels to avoid
engine damage.
It is important to rely upon your dealership
to properly diagnose and repair your vehicle. We strongly recommend only using our
genuine or our authorized re-manufactured
replacement parts engineered for your
vehicle.
Additives and Chemicals
We do not recommend using chemicals or
additives not approved by us as part of your
vehicle
’s normal maintenance. Please consult
your warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal
operating characteristic and, by itself, does
not necessarily indicate a concern or that the
fluid needs to be changed. Have discolored
fluids that also show signs of overheating or
foreign material contamination checked
immediately. Make sure to change the vehicle
’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a viable
way to change fluid for many vehicle
sub-systems during scheduled maintenance.
It is critical that systems are flushed only with
new fluid that is the same as that required
to fill and operate the system or using our
approved flushing chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections. Check Every Month
