FUEL REQUIREMENTS

2.0L Engine

This engine is designed to meet all
emission requirements, and provide
satisfactory 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 91 or higher octane "premium" gasoline will allow
these engines to operate to optimal performance.
This increase in performance is most noticeable in
hot weather or other heavier load conditions, such
as while towing.
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.
