Chrysler 300 (2019 year). Manual

Indiscriminate use of fuel system cleaning agents should be
avoided. Many of these materials intended for gum and
varnish removal may contain active solvents or similar
ingredients. These can harm fuel system gasket and dia-
phragm materials.

Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxygen-
ates such as ethanol.

CAUTION!

DO NOT use E-85, gasoline containing methanol, or
gasoline containing more than 15% ethanol (E-15). Use
of these blends may result in starting and drivability
problems, damage critical fuel system components,
cause emissions to exceed the applicable standard,
and/or cause the Malfunction Indicator Light to illu-
minate. Please observe pump labels as they should
clearly communicate if a fuel contains greater than 15%
ethanol (E-15).

Problems that result from using gasoline containing more
than 15% ethanol (E-15) or gasoline containing methanol
are not the responsibility of the manufacturer and may
void or not be covered under New Vehicle Limited War-
ranty.

Do Not Use E-85 In Non-Flex Fuel Vehicles

Non-Flex Fuel Vehicles (FFV) are compatible with gasoline
containing up to 15% ethanol (E-15). Use of gasoline with
higher ethanol content may void the New Vehicle Limited
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.

CNG And LP Fuel System Modifications

Modifications that allow the engine to run on Compressed
Natural Gas (CNG) or Liquid Propane (LP) may result in
damage to the engine, emissions, and fuel system compo-
nents. Problems that result from running CNG or LP are
not the responsibility of the manufacturer and may void or
not be covered under the New Vehicle Limited Warranty.

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. Gaso-
line 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.

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 perfor-
mance and damage the emissions control system.

(Continued)

CAUTION! (Continued)

• 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 an authorized 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 metha-
nol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or
additives is not the responsibility of the manufac-
turer 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.

Carbon Monoxide Warnings

WARNING!

Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon mon-
oxide 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.

• Guard against carbon monoxide with proper main-

tenance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi-
tions repaired promptly. Until repaired, drive with
all side windows fully open.

FLEXIBLE FUEL (3.6L ENGINE ONLY)

E-85 General Information

The information in this section is unique for Flexible Fuel
vehicles only. These vehicles can be identified by a unique
fuel filler door label that states Ethanol (E-85) or Unleaded
Gasoline Only

and/or a yellow fuel cap. Please refer to the

other sections of this manual for information on features
that are common between Flexible Fuel and Non-Flexible
Fuel powered vehicles.

CAUTION!

Only vehicles with the E-85 fuel filler door label or a
yellow gas cap can operate on E-85.

Ethanol Fuel (E-85)

E-85 is a mixture of approximately 85% ethanol and 15%
unleaded gasoline.

TECHNICAL SPECIFICATIONS

411

-------------------------------------------------------------------------------------------------------------------------------------------------------------

WARNING!

Ethanol vapors are extremely flammable and could
cause serious personal injury. Never have any smoking
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 greater than 87
(R+M)/2, or solely E-85 fuel, or any mixture of these fuels.

For best results, avoid fueling patterns alternating be-
tween 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 start-
ing and/or driveability problems during warm up.

NOTE:
• Use seasonally adjusted E-85 fuel (ASTM D5798). With

non-seasonally adjusted E-85 fuel, hard starting and
rough idle following start up may be experienced even if
the above recommendations are followed, especially
when the ambient temperature is below 32°F (0°C).

• Some additives used in regular gasoline are not fully

compatible with E-85 and may form deposits in your
engine. To eliminate driveability issues that may be
caused by these deposits, a supplemental gasoline addi-
tive, such as Mopar Injector Cleanup or Techron may be
used.

Selection Of Engine Oil For Flexible Fuel Vehicles
(E-85) And Gasoline Vehicles

FFV vehicles operated on E-85 require specially formulated
engine oils. These special requirements are included in
Mopar engine oils, and in equivalent oils meeting FCA US
Material Standard MS-6395. It is recommended that engine
oils that are API Certified and meet the requirements of
Material Standard MS-6395 be used. MS-6395 contains
additional requirements, developed during extensive fleet
testing, to provide additional protection to FCA US LLC
engines.

412

TECHNICAL SPECIFICATIONS

-------------------------------------------------------------------------------------------------------------------------------------------------------------

Starting

The characteristics of E-85 fuel make it unsuitable for use
when ambient temperatures fall below 0°F (-18°C). In the
range of 0°F (-18°C) to 32°F (0°C), an increase in the time it
takes for your engine to start may be experienced, and a
deterioration in driveability (sags and/or hesitations) until
the engine is fully warmed up. These issues may be
improved with the use of seasonally adjusted E-85 fuel.

NOTE:

Use of the engine block heater (if equipped) may

improve engine start time when using E-85 fuel when the
ambient temperature is less than 32°F (0°C).

Cruising Range

Because E-85 fuel contains less energy per gallon/liter than
gasoline, an increase in fuel consumption will be experi-
enced. The miles per gallon (mpg)/kilometers per liter and
the driving range will decrease by approximately 30%,
compared to gasoline operation.

Replacement Parts

All fuel and engine components in your Flexible Fuel
Vehicle (FFV) are designed to be compatible with ethanol.
Ethanol compatible service components are required.

CAUTION!

Replacing fuel system components with non-ethanol
compatible components can damage your vehicle.

Maintenance

CAUTION!

Do not use ethanol mixture greater than 85% in your
vehicle. It will cause difficulty in cold starting and may
affect drivability.
