octane CHRYSLER PT CRUISER 2005 1.G Owners Manual

FUEL REQUIREMENTS
2.4L Standard Engine and 2.4L Standard Turbo
Engine
Your vehicle is designed to meet all emis-
sion regulations and provide excellent fuel
economy when using high quality regular
unleaded gasoline with an octane rating of
87. The use of premium gasoline is not
recommended. The use of premium gaso-
line will provide no benefit over high quality regular
gasolines, and in some circumstances, may result in
poorer performance.
2.4L High Output Turbo Engine
Your engine is designed to meet all emis-
sion regulations and provide excellent fuel
economy and performance when usinghigh quality unleaded gasoline having an octane rating
of 91. The purchase of higher octane is not required.
The use of high quality unleaded gasoline having an
octane rating of 91 is recommended but not required.
High quality unleaded gasoline having a minumum
octane rating of 87 may safely be used for your vehicle.
Use of these lower octane gasolines, however, may result
in 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 gasoline (with the ap-
propriate octane rating for your engine) before consider-
ing service for the vehicle.

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 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 those allowed in the United States.
MMT is prohibited in Federal and California reformu-
lated 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 is not needed under normal
conditions and 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:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
damage the emission control system.
STARTING AND OPERATING 223

•An 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.
•The use of fuel additives which are now being sold as
octane enhancers is 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 is not
the responsibility of the manufacturer.
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:
•Do 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.
