2004 DODGE DURANGO octane

FUEL REQUIREMENTS
All engines (except 5.7L engines) are de-
signed to meet all emissions regulations
and provide excellent fuel economy and
performance when using high quality un-
leaded ªregularº gasoline having an oc-
tane rating of 87. The routine use of pre-
mium gasoline is not recommended.
Under normal conditions the use of premium fuel will
not provide a benefit over high quality regular gasolines
and in some circumstances may result in poorer perfor-
mance.
The 5.7L 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 routine useof premium gasoline is not recommended. The use of
premium gasoline will provide no benefit over high
quality regular and mid-grade 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. Engine damage resulting from operation with a
heavy spark knock may not be covered by the new
vehicle warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of ªregularº gasoline be-
fore considering service for the vehicle.
Over 40 auto manufacturers world-wide have issued and
endorsed consistent gasoline specifications (the World-
wide Fuel Charter, WWFC) to define fuel properties
necessary to deliver enhanced emissions, performance

242 STARTING AND OPERATING

MMT In Gasoline
MMT is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasolines
blended with MMT provide no performance advantage
beyond gasolines of the same octane number without
MMT. Gasolines blended with MMT reduce spark plug
life and reduce emission system performance. We recom-
mend that gasolines free of MMT be used in your vehicle.
The MMT content of gasoline may not be indicated on
the gasoline pump; therefore, you should ask your gaso-
line retailer whether or not his/her gasoline contains
MMT.
It is even more important to look for gasolines without
MMT in Canada because MMT can be used at levels
higher than allowed in the United States. MMT is pro-
hibited in Federal and California reformulated gasolines.
Sulfur In Gasoline
If you live in the northeast United States, your vehicle
may have been designed to meet California low emission
standards with Cleaner-Burning California reformulated
gasoline with low sulfur. If such fuels are not available in
states adopting California emission standards, your ve-
hicles will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be adversely affected. Gasoline sold outside of
California is permitted to have higher sulfur levels which
may affect the performance of the vehicle's catalytic
converter. This may cause the Check Engine or Service
Engine Soon light to illuminate. We recommend that you
try a different brand of unleaded gasoline having lower
sulfur to determine if the problem is fuel related prior to
returning your vehicle to an authorized dealer for ser-
vice.
244 STARTING AND OPERATING

²When pulling a heavy load or driving a fully loaded
vehicle when the humidity is low and the temperature
is high, use a premium unleaded fuel to help prevent
spark knock. If spark knock persists, lighten the load,
or engine piston damage may result.
²The use of fuel additives which are now being sold as
octane enhancers is not recommended. Many of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer and may not be
covered under the New Vehicle Warranty.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
²Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short period, adjust the ventilation system
to force fresh, outside air into the vehicle.
²Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time

Fog Lights
1. Rotate bulb and connector 1/4 turn counterclockwise.
2. Pull bulb off of connector.NOTE:For foglights ensure that the takeout push-
fasteners are relocated back in their positions; one in the
foglight molding and the other in the hydroform.
