FUEL
REQUIREMENTS
This engine is
designed to meet all
emission regulations,
and provide
satisfactory fuel
economy and
performance, when
using high-quality unleaded “Regular”
gasoline having a posted octane
number of 91 as specified by the
(R+M)/2 method. For optimum
performance and fuel economy the use
of “Premium” 91 octane gasoline or
higher is recommended.
While operating on gasoline with the
required octane number, hearing a light
knocking sound from the engine is not
a cause for concern. However, if the
engine is heard making a heavy
knocking sound, see your dealer
immediately. Use of gasoline with a
lower than recommended octane
number can cause engine failure and
may void or not be covered by the New
Vehicle Limited Warranty.
Poor quality gasoline can cause
problems such as hard starting, stalling,
and hesitations. If you experience these
symptoms, try another brand of
gasoline before considering service for
the vehicle.
Reformulated Gasoline
Many areas of the country require the
use of cleaner burning gasoline referred
to as “Reformulated Gasoline”.
Reformulated gasoline contains
oxygenates and are specifically blended
to reduce vehicle emissions and
improve air quality.
The use of reformulated gasoline is
recommended. Properly blended
reformulated gasoline will provide
improved performance and durability of
engine and fuel system components.
Gasoline/Oxygenate
Blends
Some fuel suppliers blend unleaded
gasoline with oxygenates such as
ethanol.
Caution!
DO NOT use gasoline containing methanol
or gasoline containing more than 15%
ethanol (E-15). Use of these blends may
result in starting and drivability problems,
damage critical fuel system components,
cause emissions to exceed the applicable
standard, and/or cause the “Malfunction
Indicator Light” to illuminate. Please
observe pump labels as they should clearly
communicate if a fuel contains greater than
15% ethanol (E-15).
Problems that result from using
gasoline containing more than 15%
ethanol (E-15) or gasoline containing
methanol are not the responsibility of
the manufacturer and may void or not
be covered under New Vehicle Limited
Warranty.
CNG And LP Fuel System
Modifications
Modifications that allow the engine to
run on compressed natural gas (CNG)
or liquid propane (LP) may result in
damage to the engine, emissions, and
fuel system components. Problems that
result from running CNG or LP are not
the responsibility of the manufacturer
and may void or not be covered under
the New Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese
Tricarbonyl (MMT) is a manganese-
containing metallic additive that is
blended into some gasoline to increase
octane. Gasoline blended with MMT
provides no performance advantage
beyond gasoline of the same octane
number without MMT. Gasoline blended
with MMT reduces spark plug life and
reduces emissions system performance
in some vehicles. The manufacturer
recommends that gasoline without
MMT be used in your vehicle. The MMT
content of gasoline may not be
indicated on the gasoline pump;
therefore, you should ask your gasoline
