FUEL REQUIREMENTS
2.0L And 2.4L Engine
These engines are designed to meet all
emissions regulations and provide opti-
mum fuel economy and performance
when using high quality unleaded “Regu-
lar” gasoline having a posted octane num-
ber of 87 as specified by the (R+M)/2 method. The use of
higher octane “Premium” gasoline is not required, 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 imme-
diately. 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 consid-
ering 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 spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The use of reformulated gasoline is recommended. Prop-
erly blended reformulated gasoline will provide im-
proved performance and durability of engine and fuel
system components.
