2008 DODGE CALIBER SRT Fuel octane

FUEL REQUIREMENTS
2.4L Turbo Engine
This engine is designed to meet all emis-
sions regulations and provide excellent fuel
economy and performance when using
high-quality premium unleaded gasoline
with an octane rating of 93.
The use of high quality unleaded gasoline having an
octane rating of 93 is recommended but not required.
High quality unleaded gasoline having a minimum oc-
tane rating of 87 may safely be used for your vehicle. Use
of these lower octane gasolines, however, may result in
significantly reduced acceleration 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.Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of ªpremiumº gasoline
before considering service for the vehicle.
Over 40 automobile manufacturers around the world
have issued and endorsed consistent gasoline specifica-
tions (the World Wide Fuel Charter, WWFC) which
define fuel properties necessary to deliver enhanced
emissions, engine performance, and durability for your
vehicle. The manufacturer recommends the use of gaso-
lines that meet the WWFC specifications if they are
available.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as ªReformulated Gasolineº.
Reformulated gasolines contain oxygenates, and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
264 STARTING AND OPERATING

The manufacturer supports the use of reformulated gaso-
lines. Properly blended reformulated gasolines will pro-
vide excellent performance and durability of engine and
fuel system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as 10% ethanol, MTBE, and ETBE. Oxygen-
ates are required in some areas of the country during the
winter months to reduce carbon monoxide emissions.
Fuels blended with these oxygenates may be used in
your vehicle.
CAUTION!
DO NOT use gasolines containing Methanol or E85
Ethanol. Use of these blends may result in starting
and driveability problems and may damage critical
fuel system components.Problems that result from using methanol/gasoline or
E85 Ethanol blends are not the responsibility of the
manufacturer. 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 gasoline 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. The manufacturer recom-
mends using gasolines without MMT. Since the MMT
content of gasoline may not be indicated on the pump,
you should ask your gasoline retailer if 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.
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 are not needed under
normal conditions and they would result in additional
cost. Therefore, you should not have to add anything to
the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle's
performance:
²The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
or damage the emission control system.
²An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out-of-tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
²The use of fuel additives, which are now being sold as
octane enhancers, are not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives are not
the responsibility of the manufacturer.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
