NGINE
This engine is designed to meet all
emissions regulations and provide
excellent fuel economy and
performance when using high-quality
unleaded "Regular" gasoline having an octane
rating of 87 as specified by the (R+M)/
2 method. The use of higher octane "Premium"
gasoline 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
TECHNICAL SPECIFICATIONS
knocking sound, see an authorized 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 considering service for the
vehicle.

EFORMULATED ASOLINE
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.
