2015 CHRYSLER 300 octane

FUEL REQUIREMENTS
3.6L Engine — If Equipped
This engine is designed to meet all emis-
sions regulations and provide excellent
fuel economy and performance when us-
ing high-quality unleaded “Regular” gaso-
line having an octane rating of 87 as speci-
fied by the (R+M)/2 method. The use of higher octane
“Premium” gasoline will not provide any benefit over
“Regular” gasoline in these engines.
While operating on gasoline with an octane number of
87, hearing a light knocking sound from the engine is not
a cause for concern. However, if the engine is heard
making a heavy knocking sound, see your dealer imme-
diately. Use of gasoline with an octane number lower
than 87 can cause engine failure and may void or 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 gasoline before consid-
ering service for the vehicle.
5.7L Engine — If Equipped
This engine is designed to meet all emis-
sions regulations and provide satisfactory
fuel economy and performance when us-
ing high-quality unleaded gasoline having
an octane range of 87 to 89 as specified by
the (R+M)/2 method. The use of 89 octane “Plus” gaso-
line is recommended for optimum performance and fuel
economy.
While operating on gasoline with an octane number of
87, hearing a light knocking sound from the engine is not
a cause for concern. However, if the engine is heard

making a heavy knocking sound, see your dealer imme-
diately. Use of gasoline with an octane number lower
than 87 can cause engine failure and may void or 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 gasoline before consid-
ering service for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline”.
Reformulated gasoline contains oxygenates and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The use of reformulated gasoline is recommended. Prop-
erly blended reformulated gasoline will provide im-
proved performance and durability of engine and fuel
system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as ethanol.
CAUTION!
DO NOT use gasoline containing Methanol or gaso-
line containing more than 10% Ethanol. Use of these
blends may result in starting and drivability prob-
lems, damage critical fuel system components, cause
emissions to exceed the applicable standard, and/or
cause the “Malfunction Indicator Light” to illumi-
nate. Please observe pump labels as they should
clearly communicate if a fuel contains greater than
10% ethanol.
Problems that result from using gasoline containing Metha-
nol or gasoline containing more than 10% ethanol are not the
responsibility of the manufacturer and may void or not be
covered under New Vehicle Limited Warranty.
414 STARTING AND OPERATING

E-85 Usage In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gaso-
line containing up to 10% ethanol (E10). Gasoline with
higher ethanol content may void the New Vehicle Lim-
ited Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•Operate in a lean mode.
•OBD II “Malfunction Indicator Light” on.
•Poor engine performance.
•Poor cold start and cold drivability.
•Increased risk for fuel system component corrosion.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT)
is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
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 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:
•The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine per-
formance and damage the emissions control sys-
tem.
•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 ser-
vice. Contact your authorized dealer for service
assistance.
(Continued)
CAUTION!(Continued)
•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 perfor-
mance problems resulting from the use of such
fuels or additives is not the responsibility of the
manufacturer and may void or not be covered
under the New Vehicle Limited Warranty.
NOTE:Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.
416 STARTING AND OPERATING

CAUTION!
Only vehicles with the E-85 fuel filler door label can
operate on E-85.
Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% ethanol and 15%
unleaded gasoline.
WARNING!
Ethanol vapors are extremely flammable and could
cause serious personal injury. Never have any smok-
ing materials lit or products that can cause spark in or
near the vehicle when removing the fuel filler tube
cap (gas cap) or filling the tank. Do not use E-85 as a
cleaning agent and never use it near an open flame.
Fuel Requirements
If your vehicle is E-85 compatible, it will operate on
unleaded gasoline with any octane rating, or solely E-85
fuel, or any mixture of these fuels.
For best results, avoid fueling patterns alternating
between E-85 and unleaded gasoline.
When switching fuel types:
•Add 5 gallons (19 Liters) or more when refueling.
•Drive the vehicle immediately after refueling for at
least 5 miles (8 km).
Observing these precautions will avoid possible hard
starting and/or driveability problems during warm up.
