Choosing the Right Fuel With a Flex Fuel Vehicle (If Equipped)
Use only UNLEADED gasoline or UNLEADED gasoline blended with a
maximum of 85% ethanol (E-85) in your Flex Fuel Vehicle (FFV). If
your vehicle is flex fuel capable, it will have a yellow bezel placed over
the fuel fill inlet.
Do not use:
•
Fuels containing more than 85% ethanol or E-100 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 (The use of leaded fuel is prohibited by law).
Use of any fuel other than recommended fuel can cause powertrain
damage, impair the emission control system or cause loss of vehicle
performance. Any damage to a vehicle that is caused by use of fuel not
recommended will not be covered under warranty.
Octane Recommendations
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 under most driving conditions 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.
