FUEL REQUIREMENTS

6.2L Supercharged And 6.4L Engine

These engines are designed to meet all
emissions regulations, provide optimal
fuel economy and performance when
using
mium" gasoline having a posted octane
number of 91 as specified by the
high-quality unleaded
(R+M)/2 method. The use of 91 or higher octane "Pre-
mium" gasoline is required in these engines.
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 immedi-
ately. 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 consider-
ing service for the vehicle.

burning gasoline referred to as "Reformulated Gasoline".
Reformulated gasoline contains oxygenates and are specifi-
cally blended to reduce vehicle emissions and improve air
quality.
The use of reformulated gasoline is recommended. Prop-
"Pre-
erly blended reformulated gasoline will provide improved
performance and durability of engine and fuel system
components.
