FUEL QUALITY
Note:
We recommend that you use only
high quality fuel without additives or other
engine treatments.
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.
Your vehicle was not designed to use fuel
or fuel additives with metallic compounds,
including manganese-based additives.
Diesel Engine
Refer to the diesel supplement for
information regarding diesel fuel
recommendations and requirements of
your diesel-powered truck.
Choosing the Right Fuel With a
Flex Fuel Vehicle (If Equipped)
Note: If your vehicle is flex fuel capable, it
will have a yellow bezel placed over the fuel
fill inlet.
Flex fuel vehicles are designed to use
unleaded gasoline or an ethanol fuel blend
that contain up to 85% ethanol. It is also
acceptable to use any mixture of unleaded
gasoline and ethanol fuel that contains up
to 85% ethanol. An ethanol fuel blend that
contains 85% ethanol is labeled as E85 at
the service station. It is best not to alternate repeatedly
between gasoline and E85. If you do switch
fuels, it is recommended that you add as
much fuel as possible—at least half a tank.
Do not add less than five gallons (18.9
liters) when refueling. You should drive the
vehicle immediately after refueling for at
least 5 miles (8 kilometers) to allow the
vehicle to adapt to the change in ethanol
concentration. If you exclusively use E85
fuel, it is recommended to fill the fuel tank
with regular unleaded gasoline at each
scheduled oil change.
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.
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:
