FORD 2013 Fusion Hybrid v.1 - Manual (Page 160)

FUEL QUALITY
Note: Use of any fuel other than those
recommended may cause powertrain
damage, a loss of vehicle performance and
repairs may not be covered under warranty.
Choosing the Right Fuel
Use only UNLEADED fuel or UNLEADED
fuel blended with a maximum of 15%
ethanol. Do not use fuel ethanol (E85),
diesel fuel, fuel-methanol, leaded fuel or
any other fuel because it could damage or
impair the emission control system. The
use of leaded fuel is prohibited by law.
Octane Recommendations
Regular unleaded gasoline with a pump
(R+M)/2 octane rating of 87 is
recommended. Some fuel 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.
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.
Fuel Freshness Mode (Energi
Vehicles Only)
Fuel freshness mode keeps the fuel system
functional and the fuel fresh. Old fuel can
damage the engine and fuel system. If
operated continuously in EV Now mode,
fuel freshness mode will use up to an entire
tank of fuel down to 1 gallon (3.8 liters)
every 18 months. Fuel freshness mode will
operate the vehicle in hybrid mode – EV
Later to consume the fuel. During fuel
freshness mode EV Now and Auto EV will
not be available.
Fuel freshness mode will provide messages
in the information displays screen to
indicate that it is functioning. Fuel
freshness mode will run until the needed
amount of fuel has been consumed.
Adding at least 1 gallon (3.8 liters) of fresh
fuel to the tank will suspend the fuel
freshness mode. The vehicle will determine
when to run the fuel freshness mode based
on how much fuel was added to the tank,
and on how long it has been driven in EV
Now mode. Up to 18 months of additional
time will be gained if an equal amount of
fresh fuel is added to the existing amount
of fuel that is in the tank.
Fuel freshness mode will eventually bring
the tank level to 1 gallon (3.8 liters) if fuel
is not added. This feature will not activate
if your fuel tank has 1 gallon (3.8 liters) of
fuel or less.
If the vehicle is used in a manner that rarely
runs the engine, it is recommended to keep
the fuel level to about the amount that will
be consumed every 18 months. For
example, if four gallons are used on
average, let the fuel level reduce to about
1/8 of a tank, then add in 4 gallons (15
liters). This will keep the fuel fresh and
prevent fuel freshness mode from
activating.

Fuel vapor burns violently and a fuel
fire can cause severe injuries.
