2.4L Engine

All available gasoline engines are de-
signed to meet all emissions regulations
and provide excellent fuel economy and
performance when using high quality
unleaded "regular" gasoline having a
octane rating of 87 using the (R+M)/2
method. The use of premium gasoline is
not recommended, as it will not provide any benefit over
regular gasoline in these engines.
While operating on gasoline with an octane number of 87,
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 an octane number lower than 87 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 consider-
ing 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. Prop-
erly 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 oxygen-
ates 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 emis-
sions to exceed the applicable standard, and/or cause
the "Malfunction Indicator Light" to illuminate. Please
observe pump labels as they should clearly communi-
cate if a fuel contains greater than 15% ethanol (E-15).
