304 STARTING AND OPERATING

FUEL REQUIREMENTS

2.4L and 2.7L Engine

All engines are designed to meet all emis-

high quality unleaded "regular" gasoline
having an octane rating of 87. The use of
premium gasoline is not recommended, as
it will not provide any benefit over regular gasoline in
these engines.

3.5L Engine

The 3.5L engine is designed to meet all
emissions regulations and provide satisfac-
tory fuel economy and performance when
using high-quality unleaded gasoline hav-
ing an octane range of 87 to 89. The manu-
facturer recommends the use of 89 octane
for optimum performance. The use of premium gasoline
is not recommended, as it will not provide any benefit
over regular gasoline in these engines.
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 gasoline (with the ap-
propriate octane rating for your engine) before consider-

Over 40 automobile manufacturers around the world

tions (the World Wide Fuel Charter, WWFC) which
define fuel properties necessary to deliver enhanced
emissions, engine performance, and durability for your
