2021 DODGE CHARGER octane

TECHNICAL SPECIFICATIONS297
Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/bolt
(do not insert it halfway).
NOTE:If in doubt about the correct tightness, have them
checked with a torque wrench by an authorized
dealer or service station.
After 25 miles (40 km), check the lug nut/bolt
torque to be sure that all the lug nuts/bolts are
properly tightened.

FUEL REQUIREMENTS
While operating on gasoline with the required
octane number, 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 a dealer immediately. Use of
gasoline with a lower than recommended octane
number can cause engine failure and may void the
New Vehicle Limited 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 considering service for the vehicle.
3.6L ENGINE
This engine is designed to meet all
emissions regulations and provide
excellent fuel economy and performance
when using high-quality unleaded regular
gasoline having an octane rating of 87 as specified
by the (R+M)/2 method. The use of higher octane
premium gasoline will not provide any benefit over
regular gasoline in these engines.
5.7L ENGINE
Do not use E-85 flex fuel or ethanol blends greater
than 15% in this engine.

This engine is designed to meet all
emissions regulations and provide
satisfactory fuel economy and
performance when using 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 gasoline is recommended for
optimum performance and fuel economy.

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 specifically blended to reduce
vehicle emissions and improve air quality.

The use of reformulated gasoline is recommended.
Properly blended reformulated gasoline will
provide improved performance and durability
of engine and fuel system components.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts/bolts fully until
the vehicle has been lowered. Failure to follow
this warning may result in personal injury.

298TECHNICAL SPECIFICATIONS
MATERIALS ADDED TO FUEL
Besides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives are
recommended. Using gasolines that have these
additives will help improve fuel economy, reduce
emissions, and maintain vehicle performance.
Designated TOP TIER Detergent Gasoline
contains a higher level of detergents to
further aide in minimizing engine and
fuel system deposits. When available,
the usage of TOP TIER Detergent gasoline is
recommended. Visit
www.toptiergas.com for a
list of TOP TIER Detergent Gasoline Retailers.
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 diaphragm materials.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with
oxygenates such as ethanol.

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 Warranty.

DO NOT USE E-85 IN NON-FLEX FUEL
V
EHICLES
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
M
ODIFICATIONS

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 components. 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.

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 illuminate. Please
observe pump labels as they should clearly
communicate if a fuel contains greater than 15%
ethanol (E-15).

TECHNICAL SPECIFICATIONS299
METHYLCYCLOPENTADIENYL MANGANESE TRICARBONYL (MMT) IN GASOLINE
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.

(Organic Additive Technology).
Engine Oil – 3.6L/5.7L Engine We recommend you use API Certified SAE 5W-20 Engine Oil, meeting the requirements of the manufacturer
Material Standard MS-6395 such as Mopar®, Pennzoil, and Shell Helix Ultra. Refer to your engine oil filler cap
for correct SAE grade.
Engine Oil Filter We recommend you use a Mopar® Engine Oil Filter. If a Mopar® Engine Oil Filter is unavailable only use filters
that meet or exceed SAE/USCAR-36 Filter Performance Requirements.
Fuel Selection – 3.6L Engine 87 Octane (R+M)/2 Method, 0-15% Ethanol.
Fuel Selection – 5.7L Engine 89 Octane Recommended – 87 Octane acceptable (R+M)/2 Method, 0-15% Ethanol.
CAUTION!
Mixing of engine coolant (antifreeze) other than specified Organic Additive Technology (OAT) engine coolant (antifreeze), may result in engine damage and
may decrease corrosion protection. Organic Additive Technology (OAT) engine coolant is different and should not be mixed with Hybrid Organic Additive Tech -
nology (HOAT) engine coolant (antifreeze) or any “globally compatible” coolant (antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into the
cooling system in an emergency, the cooling system will need to be drained, flushed, and refilled with fresh OAT coolant (conforming to MS.90032), by an
authorized dealer as soon as possible.
Do not use water alone or alcohol-based engine coolant (antifreeze) products. Do not use additional rust inhibitors or antirust products, as they may not be
compatible with the radiator engine coolant and may plug the radiator.
This vehicle has not been designed for use with propylene glycol-based engine coolant (antifreeze). Use of propylene glycol-based engine coolant (antifreeze)
is not recommended.
