law and could damage your
vehicle.
Your vehicle was not designed to
use fuel or fuel additives with
metallic compounds, including
manganese-based compounds
containing MMT.
Vehicles certified to California
emission standards (indicated on
the underhood Vehicle Emissions
Control Information label) are
designed to operate on California
reformulated gasolines. If
California reformulated gasoline is
not available when you refuel, your
vehicle can be operated on
non-California fuels. However, even
though your engine will perform
adequately on other gasolines, the
performance of the emission
control devices and systems may
be adversely affected.
Repair of damage caused by using
a fuel that your vehicle was not
designed for may not be covered
by your warranty.
Octane recommendations
Your vehicle is designed to use
regular unleaded with an (R+M)/2
octane rating of 87. We do not
recommend gasolines labeled as
ªregularº in high altitude areas that
are sold with octane ratings of 86
or even less.
Do not be concerned if your
vehicle sometimes knocks lightly.
However, if it knocks heavily under
most driving conditions on fuel

with the recommended octane, see
your dealer or a qualified service
technician to prevent any engine
damage.
Fuel quality
If you are experiencing starting,
rough idle or hesitation problems
try a different brand of fuel. If the
condition persists, see your dealer
or a qualified service technician.
The American Automobile
Manufacturers Association (AAMA)
issued a gasoline specification to
provide information on high quality
fuels that optimize the
performance of your vehicle. We
recommend the use of gasolines
that meet the AAMA specification
if they are available.
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.
