octane CHRYSLER CROSSFIRE 2008 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.
222 STARTING AND OPERATING

Problems that result from using methanol/gasoline
blends are not the responsibility of DaimlerChrysler
Corporation and may not be covered by the Limited
Warranty. While MTBE is an oxygenate made from
Methanol, it does not have the negative effects of Metha-
nol.
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
Corporation 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

RECOMMENDED FLUIDS, LUBRICANTS AND GENUINE PARTS
Engine
Component Fluids, Lubricants and Genuine Parts
Engine Coolant Use coolant approved to MB 325.0, such as Valvoline GO5, or an equivalent
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.
