2023 JEEP WAGONEER octane

372TECHNICAL SPECIFICATIONS
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 half way).
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 an octane number lower
than recommended 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.
3.0L STANDARD OUTPUT 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
requirements, and provide satisfactory 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 91 or higher octane premium
gasoline will allow these engines to operate to optimal
performance. This increase in performance is most
noticeable in hot weather or under heavy load conditions
such as while towing.
3.0L HIGH OUTPUT ENGINE
Do not use E-85 flex fuel or ethanol blends greater than
15% in this engine.
This engine is designed to meet all emission
regulations, provide optimal fuel economy and
performance when using high-quality unleaded
premium gasoline having a posted octane
number of 91 as specified by the (R+M)/2 method. The
use of 91 or higher octane premium gasoline is required
in this engine.
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 emission
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.
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.

TECHNICAL SPECIFICATIONS373
6.4L ENGINE
Do not use E-85 flex fuel or ethanol blends greater than
15% in this engine.
This engine is designed to meet all emission
regulations, provide optimal fuel economy and
performance when using high-quality unleaded
premium gasoline having a posted octane
number of 91 as specified by the (R+M)/2 method. The
use of 91 or higher octane premium gasoline is required
in these engines.
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.
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.
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).

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.
METHYLCYCLOPENTADIENYL
M
ANGANESE TRICARBONYL (MMT) IN
G
ASOLINE
MMT is a manganese-containing metallic additive that is
blended into some gasolines 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 the gasoline retailer whether the
gasoline contains MMT. MMT is prohibited in Federal and
California reformulated gasoline.
FUEL SYSTEM CAUTIONS
NOTE:Intentional tampering with the emissions control system
can result in civil penalties being assessed against you.
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.
 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 meth -
anol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or addi -
tives is not the responsibility of the manufacturer
and may void or not be covered under the New
Vehicle Limited Warranty.
