FORD 2014 Fusion v.3 - Manual (Page 149)

Regular unleaded gasoline with a pump
(R+M)/2 octane rating of 87 is
recommended. Some stations offer fuels
posted as "Regular" with an octane rating
below 87, particularly in high altitude areas.
Fuels with octane levels below 87 are not
recommended. Premium fuel will provide
improved performance and is
recommended for severe duty usage such
as trailer tow.
Do not be concerned if your engine
sometimes knocks lightly. However, if it
knocks heavily while you are using fuel with
the recommended octane rating, see your
authorized dealer to prevent any engine
damage.
RUNNING OUT OF FUEL
Avoid running out of fuel because this
situation may have an adverse effect on
powertrain components.
If you have run out of fuel:
• You may need to cycle the ignition from
off to on several times after refueling
to allow the fuel system to pump the
fuel from the tank to the engine. On
restarting, cranking time will take a few
seconds longer than normal. With
keyless ignition, just start the engine.
Crank time will be longer than usual.
• Normally, adding 1 gallon (3.8 liters) of
fuel is enough to restart the engine. If
the vehicle is out of fuel and on a steep
grade, more than 1 gallon (3.8 liters)
may be required.
• The service engine soon indicator may
come on. For more information on the
service engine soon indicator, See
Warning Lamps and Indicators
(page 82).
Refilling With a Portable Fuel
Container
WARNINGS
Do not insert the nozzle of portable
fuel containers or aftermarket
funnels into the capless fuel system.
This could damage the fuel system and its
seal, and may cause fuel to run onto the
ground instead of filling the tank, which
could result in serious personal injury.
Do not try to pry open or push open
the capless fuel system with foreign
objects. This could damage the fuel
system and its seal and cause injury to you
or others.
Note: Do not use aftermarket funnels; they
will not work with the capless fuel system
and can damage it. The included fuel funnel
has been specially designed to work safely
with your vehicle.
When filling the vehicle’s fuel tank from a
portable fuel container, use the funnel
included with the vehicle.
