Fuel Quality - Ford 2013 Flex Owner's Manual

• Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
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 also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
• Be particularly careful if you are taking "Antabuse" or other forms of
disulfiram for the treatment of alcoholism. Breathing gasoline vapors, or
skin contact could cause an adverse reaction. In sensitive individuals,
serious personal injury or sickness may result. If fuel is splashed on the
skin, promptly wash skin thoroughly with soap and water. Consult a
physician immediately if you experience an adverse reaction.

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
3.5L/3.7L V6 engines
"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.
3.5L V6 EcoBoost™ engine
"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.
