FUEL REQUIREMENTS

Your vehicle is designed to meet all emis-
sion regulations and provide excellent fuel
economy when using high quality regular
unleaded gasoline with an octane rating of
87. The use of premium gasoline is not
recommended. The use of premium gaso-
line will provide no benefit over high quality regular
gasolines, and in some circumstances, may result in
poorer performance.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required.
Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of "regular" gasoline be-
fore considering service for the vehicle.
