Fuel Quality; Octane Recommendations; Choosing The Right Fuel - Ford 2015 C-MAX HYBRID Owner's Manual

FUEL QUALITY

Note: Your warranty will not cover any
vehicle damage, powertrain damage, loss
of vehicle performance or repairs to your
vehicle, caused by the use of fuel not
recommended.

Choosing the Right Fuel

Use only UNLEADED gasoline or
UNLEADED gasoline blended with a
maximum of 15% ethanol in your gasoline
vehicle. If your vehicle is a Flex Fuel Vehicle
(FFV), it will have a yellow bezel placed
over the fuel fill inlet.
Do not use:
• Fuels containing more than 15%
ethanol or E-85 fuel.
• Fuels containing methanol.
• Fuels containing metallic based
additives, including manganese-based
compounds.
• Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Prohibited by law, you cannot use
leaded fuel.
Note: Use of any fuel other than the
recommended fuel can cause powertrain
damage, impair the emission control system
or cause loss of vehicle performance. Any
damage to your vehicle that is caused by
the use of fuel not recommended will not
be covered under warranty.

Octane Recommendations

We recommend regular unleaded gasoline
with a pump (R+M)/2 octane rating of 87.
Some stations offer fuels posted as regular
with an octane rating below 87, particularly
in high altitude areas. We do not
recommend fuels with an octane rating
below 87. Premium fuel will provide
improved performance and is
recommended for severe duty usage such
as trailer tow.
Fuel Freshness Mode (Energi
Vehicles Only)
This feature helps keep the fuel system
functional and the fuel fresh.
If you mainly operate your vehicle in plug-in
power mode using electricity from plugging
in without refueling, the gasoline in the fuel
tank will become stale due to aging over
an extended period. Stale gasoline can
damage the engine and fuel system.
Your vehicle will automatically operate in
fuel freshness mode if you do not refill your
vehicle with fresh fuel within an 18-month
period. The design of fuel freshness mode
protects your vehicle from potential engine
and fuel system damage caused by using
stale fuel.
Note: If you do not add new fuel during an
18-month period, fuel freshness mode will
consume fuel until you have about 1 gal
(3.8 L) in the tank.
During fuel freshness mode:
•
•
•
139
The information display screen will
indicate that fuel freshness mode is
active.
The vehicle will only run in hybrid mode.
EV Now will not be available.
Most of the plug-in power will be
stored until fuel freshness mode is
completed.
