2021 JEEP PATRIOT fuel additives

the “SERVICE TPM SYSTEM” message will no
longer be displayed as long as no system fault
exists.
To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPM sensors. Then, drive the
vehicle for up to 10 minutes above 15 mph
(24 km/h). The TPMS will chime, the “TPM
Telltale Light” will flash on and off for 75 sec-
onds and then turn off, and the Electronic
Vehicle Information Center (EVIC) will display
the “SERVICE TPM SYSTEM” message. The
EVIC will also display pressure values in place
of the dashes. On the next ignition switch cycle,
the “SERVICE TPM SYSTEM” message will no
longer be displayed as long as no system fault
exists.
FUEL REQUIREMENTS —
GASOLINE ENGINE
All gasoline engines are designed to meet all
emissions regulations and provide excellent
fuel economy and performance when using
high quality unleaded gasoline with a minimum
research octane rating (RON) of 91.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 before considering service for the
vehicle.
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 may help improve fuel economy, re-
duce emissions, and maintain vehicle perfor-
mance.
Poor quality gasoline can cause problems such
as hard starting, stalling and stumble. If you
experience these problems, try another brand
of gasoline before considering service for the
vehicle.
Methanol(Methyl) is used in a variety of concentrations
when blended with unleaded gasoline. You mayfind fuels containing 3% or more methanol
along with other alcohols called cosolvents.
Problems that result from using methanol/
gasoline blends are not the responsibility of the
manufacturer.
CAUTION!
Do not use gasolines containing Methanol.
Use of these blends may result in starting
and drivability problems and may damage
critical fuel system components.
EthanolThe manufacturer recommends that your ve-
hicle be operated on fuel containing no more
than 15% ethanol. Purchasing your fuel from a
reputable supplier may reduce the risk of ex-
ceeding this 15% limit and/or of receiving fuel
with abnormal properties. It should also be
noted that an increase in fuel consumption
should be expected when using ethanol-
blended fuels, due to the lower energy content
of ethanol. Problems that result from using
210

methanol/gasoline or E-85 ethanol blends are
not the responsibility of the manufacturer.
CAUTION!
Use of fuel with Ethanol content higher than
15% may result in engine malfunction, start-
ing and operating difficulties, and materials
degradation. These adverse effects could
result in permanent damage to your vehicle.
Clean Air GasolineMany gasolines are now being blended that
contribute to cleaner air, especially in those
areas where air pollution levels are high. These
new blends provide a cleaner burning fuel and
some are referred to as “reformulated gasoline.”
The manufacturer supports these efforts toward
cleaner air. You can help by using these blends
as they become available.
MMT In GasolineMMT is a manganese containing metallic addi-
tive that is blended into some gasoline to in-
crease octane. Gasoline blended with MMTprovides no performance advantage beyond
gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces
spark plug life and reduces emission system
performance in some vehicles. The manufac-
turer 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 or not his/her gasoline contains
MMT.
Materials Added To FuelBesides 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, re-
duce emissions, and maintain vehicle perfor-
mance.
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these ma-
terials intended for gum and varnish removal
may contain active solvents or similar ingredi-ents. These can harm fuel system gasket and
diaphragm materials.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to pre-
vent carbon monoxide poisoning:
•Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odor-
less 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.
