FUEL AND REFUELING

PRECAUTIONS

WARNING: Fuels can cause serious

injury or death if misused or mishandled.

WARNING: Fuel may contain

benzene, which is a cancer-causing

agent.

WARNING: Read and follow all the

instructions on the pump island.

WARNING: When refueling always

shut the engine off and never allow

sparks or open flames near the fuel tank

filler valve. Never smoke or use a cell

phone while refueling. Fuel vapor is

extremely hazardous under certain

conditions. Avoid inhaling excess fumes.

Follow these guidelines when refueling:

• Extinguish all smoking materials and

any open flames before refueling your

vehicle.

• Switch the engine off before refueling.

• Automotive fuels can be harmful or

fatal if swallowed. Fuel is highly toxic

and if swallowed can cause death or

permanent injury. If fuel is swallowed

immediately call a physician, even if no

symptoms are immediately apparent.

The toxic effects of fuel may not be

apparent for hours.

• Avoid inhaling fuel vapors. Inhaling fuel

vapor can lead to eye and respiratory

tract irritation. In severe cases,

excessive or prolonged breathing of

fuel vapor can cause serious illness and

permanent injury.

• Avoid getting fuel in your eyes. If you

splash fuel in your eyes, immediately

remove contact lenses, if worn, flush

with water for 15 minutes and seek

medical attention. Failure to seek

proper medical attention could lead to

permanent injury.

• Fuels can be harmful if absorbed

through the skin. If you splash fuel on

your skin, clothing or both, promptly

remove contaminated clothing and

thoroughly wash your skin with soap

and water. Repeated or prolonged skin

contact causes skin irritation.

• Be particularly careful if you are taking

Antabuse or other forms of Disulfiram

for the treatment of alcoholism.

Breathing fuel vapors could cause an

adverse reaction, serious personal

injury or sickness. Immediately call a

physician if you experience any adverse

reactions.

FUEL QUALITY

SELECTING THE CORRECT FUEL

E161513

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.

150

Mustang (CZJ) Canada/Mexico/United States of America, enUSA, Edition date: 202407, DOM

Fuel and Refueling

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 260).

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.

For additional information, visit

www.toptiergas.com.

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

(E15) 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.

LOCATING THE FUEL FILLER

FUNNEL

The fuel filler funnel is under the luggage

compartment floor covering.

RUNNING OUT OF FUEL

FILLING A PORTABLE FUEL

CONTAINER

WARNING: Flow of fuel through a

fuel pump nozzle can produce static

electricity. This can cause a fire if you are

filling an ungrounded fuel container.

Use the following guidelines to avoid

electrostatic charge build-up, which can

produce a spark, when filling an

ungrounded fuel container:

• Only use an approved fuel container to

transfer fuel to your vehicle. Place the

container on the ground when filling it.

• Do not fill a fuel container when it is

inside your vehicle (including the cargo

area).

• Keep the fuel pump nozzle in contact

with the fuel container when filling it.

• Do not use a device that holds the fuel

pump nozzle lever in the fill position.

Fuel and Refueling

ADDING FUEL FROM A PORTABLE

FUEL CONTAINER

WARNING: Do not insert the nozzle

of a fuel container or an aftermarket

funnel into the fuel filler neck. This may

damage the fuel system filler neck or its

seal and cause fuel to run onto the

ground.

WARNING: Do not pry open the

fuel tank filler valve. This could damage

the fuel system. Failure to follow this

instruction could result in fire, personal

injury or death.

WARNING: Do not dispose of fuel

in the household refuse or the public

sewage system. Use an authorized waste

disposal facility.

When refueling the vehicle fuel tank from

a fuel container, use the fuel filler funnel

included with your vehicle. See Locating

the Fuel Filler Funnel (page 151).

Note: Do not use aftermarket funnels as

they may not work with the capless fuel

system and can damage it.

When refueling the vehicle fuel tank from

a fuel container, do the following:

1. Fully open the fuel filler door.

E157452

2. Fully insert the fuel filler funnel into the

fuel filler inlet.

3. Add fuel to your vehicle from the fuel

container.

4. Remove the fuel filler funnel.

5. Fully close the fuel filler door.

6. Clean the fuel filler funnel and place it

back in your vehicle or correctly dispose

of it.

Note: If your vehicle runs out of fuel add a

minimum of 1.3 gal (5 L) of fuel to restart

the engine.

Note: You may need to switch 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. When

restarting, cranking time takes a few

seconds longer than normal.

Note: Extra funnels can be purchased from

an authorized dealer if you choose to

dispose of the funnel.
