FUEL REQUIREMENTS
3.6L Engine
These engines are designed to meet all emis-
sions regulations and provide excellent fuel
economy and performance when using high-
quality unleaded gasoline with a minimum Re-
search Octane Number (RON) of 91.
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 before considering service for the
vehicle.
Over 40 auto manufacturers worldwide have
issued and endorsed consistent gasoline speci-
fications (the Worldwide Fuel Charter, WWFC)
which define fuel properties necessary to de-
liver enhanced emissions, performance, and
durability for your vehicle. The manufacturer
recommends the use of gasoline that meets the
WWFC specifications if they are available.
Besides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives are
recommended. Using gasolines that have these
additives may help improve fuel economy, re-
duce emissions, and maintain vehicle perfor-
mance.
Poor quality gasoline can cause problems such
as hard starting, stalling and stumble. If you
experience these problems, try another brand
of gasoline before considering service for the
vehicle.

mends the use of a 95 Research Octane Num-
