octane CHRYSLER CROSSFIRE 2007 1.G Owners Manual

FUEL REQUIREMENTS
Your engine is designed to meet all emis-
sions regulations and provide satisfactory
fuel economy and optimum performance
when using high quality unleaded gaso-
line having an octane rating of 91 or
higher. DaimlerChrysler Corporation re-
quires the use of 91 octane or higher premium fuel to
minimize the potential for engine damage.
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 should be reported to
your authorized dealer immediately. Engine damage
resulting from operating 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 stumble. If you experience these
problems, try another brand of gasoline before consider-
ing service for the vehicle.
186 STARTING AND OPERATING

MMT in Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasolines to increase the octane num-
ber. Gasolines blended with MMT offer no performance
advantage beyond gasolines of the same octane number
without MMT. Gasolines blended with MMT have shown
to reduce spark plug life and reduce emission system
performance in some vehicles. DaimlerChrysler Corpo-
ration recommends using gasolines without MMT. Since
the MMT content of gasoline may not be indicated on the
pump, you should ask your gasoline retailer whether or
not his/her gasoline contains MMT.
MMT is prohibited in both Federal and California refor-
mulated gasolines.
In Canada, MMT can be used at levels higher than those
allowed in the United States. For this reason, it is even
more important to look for gasolines without MMT in
Canada.
Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and would result in unnecessary cost. There-
fore, you should not have to add anything to the fuel.
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-
hicle 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 light to illuminate. DaimlerChrysler
Corporation recommends that you try a different brand

extended life coolant.
Engine Oil Only use synthetic engine oils, approved to MB 229.3 or MB 229.5, such as
Mobil 1 SAE 0W-40. The FSS may not alert for an oil change at the proper
interval if an unapproved engine oil is used; engine damage and reduced
engine life may result.
