2021 JEEP PATRIOT checking oil

Loose Fuel Filler Cap MessageAfter fuel is added, the vehicle diagnostic sys-
tem can determine if the fuel filler cap is possi-
bly loose or improperly installed. A “gASCAP”
message will be displayed in the instrument
cluster. Tighten the gas cap until a “clicking”
sound is heard. This is an indication that the gas
cap is properly tightened. Push the trip odom-
eter RESET button to turn off the message. If
the problem persists, the message will appear
the next time the vehicle is started. This might
indicate a damaged cap. If the problem is
detected twice in a row, the system will turn on
the MIL. Resolving the problem will turn the MIL
light off.
REPLACEMENT PARTS
Use of genuine MOPAR parts for normal/
scheduled maintenance and repairs is highly
recommended to ensure the designed perfor-
mance. Damage or failures caused by the use
of non-MOPAR parts for maintenance and re-
pairs will not be covered by the New Vehicle
Limited Warranty.
MAINTENANCE PROCEDURES
The pages that follow contain therequired
maintenance services determined by the engi-
neers who designed your vehicle.
Besides those maintenance items specified in
the fixed “Maintenance Schedule”, there are
other components which may require servicing
or replacement in the future.
CAUTION!
•Failure to properly maintain your vehicle or
perform repairs and service when neces-
sary could result in more costly repairs,
damage to other components or negatively
impact vehicle performance. Immediately
have potential malfunctions examined by
an authorized dealer or qualified repair
center.
(Continued)
CAUTION!(Continued)
•Your vehicle has been built with improved
fluids that protect the performance and
durability of your vehicle and also allow
extended maintenance intervals. Do not
use chemical flushes in these components
as the chemicals can damage your engine,
transmission, or air conditioning. Such
damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed
because of component malfunction, use
only the specified fluid for the flushing
procedure.
Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine
oil must be maintained at the correct level.
Check the oil level at regular intervals, such as
every fuel stop.
The best time to check the engine oil level is
about five minutes after a fully warmed engine is
shut off. Do not check oil level before starting
256

the engine after it has sat overnight. Checking
engine oil level when the engine is cold will give
you an incorrect reading.
Checking the oil while the vehicle is on level
ground and only when the engine is hot, will
improve the accuracy of the oil level readings.
Maintain the oil level between the range mark-
ings on the dipstick. The range markings will
consist of a crosshatch zone that says SAFE or
a crosshatch zone that says MIN at the low end
of the range and MAX at the high end of the
range. Adding one quart of oil when the reading
is at the low end of the indicated range will result
in the oil level at the full end of the indicator
range.
CAUTION!
Do not overfill the engine. Overfilling the
engine will cause oil aeration, which can lead
to loss of oil pressure and an increase in oil
temperature. This could damage your en-
gine. Also, be sure the oil fill cap is replaced
and tightened after adding oil.Change Engine Oil – All Engines
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.
Engine Oil Selection
For best performance and maximum protection
under all types of operating conditions, the manu-
facturer only recommends engine oils that are API
certified and meet the requirements of FCA Ma-
terial Standard MS-6395 or ACEA A1/B1.
American Petroleum Institute (API) Engine
Oil Identification Symbol
This symbol means that
the oil has been certified
by the American Petro-
leum Institute (API). The
manufacturer only rec-
ommends API Certified
engine oils.
This symbol certifies 0W-20, 5W-20, 0W-30,
5W-30 and 10W-30 engine oils.
CAUTION!
Do not use chemical flushes in your engine
oil as the chemicals can damage your en-
gine. Such damage is not covered by the
New Vehicle Limited Warranty.
Engine Oil Viscosity (SAE Grade)
MOPAR SAE 5W-20 engine oil is recom-
mended for all operating temperatures. This
engine oil improves low temperature starting
and vehicle fuel economy.
The engine oil filler cap also shows the recom-
mended engine oil viscosity for your engine. For
information on engine oil filler cap location, refer
to “Engine Compartment” in “Maintaining Your
Vehicle” for further information.
NOTE:
MOPAR SAE 5W-30 engine oil approved to
FCA MS-6395 or FCA Material Standard
9.55535-CR1 may be used when SAE 5W-20
engine oil meeting FCA MS-6395 or FCA
Material Standard 9.55535-CR1 is not avail-
able.

MAINTENANCE SCHEDULE
Maintenance Schedule — Gasoline
Engine
The Scheduled Maintenance services listed in
this manual must be done at the times or
mileages specified to protect your vehicle war-
ranty and ensure the best vehicle performance
and reliability. More frequent maintenance may
be needed for vehicles in severe operating
conditions, such as dusty areas and very short
trip driving. Inspection and service should also
be done anytime a malfunction is suspected.
The oil change indicator system will remind you
that it is time to take your vehicle in for sched-
uled maintenance.
On Non-EVIC equipped vehicles, “CHANgE
OIL” will flash in the instrument cluster odom-
eter and a single chime will sound, indicating
that an oil change is necessary.
The oil change indicator message will illuminate
approximately 7,000 miles (11,200 km) after the
most recent oil change was performed. Have
your vehicle serviced as soon as possible,
within 500 miles (800 km). However, an earlieroil change at 4,500 miles (7,500 km) may be
required if the vehicle is operated under “Se-
vere Duty Conditions” later in this section.
NOTE:
•The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicle’s oil if it has been 12
months since your last oil change even if
the oil change indicator message is NOT
illuminated.
•Change your engine oil more often if you
drive your vehicle off-road for an ex-
tended period of time.
•Under no circumstances should oil
change intervals exceed 7,500 miles
(12,000 km) or 12 months, whichever
comes first.
Your dealer will reset the oil change indicator
message after completing the scheduled oil
change. If this scheduled oil change is per-
formed by someone other than your dealer, the
message can be reset by referring to the steps
described under “Instrument ClusterDescription/Odometer/Trip Odometer” in “Un-
derstanding Your Instrument Panel” for further
information.
Once A Month Or Before A Long Trip
•Check the engine oil level about five minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is on
level ground will improve the accuracy of the
oil level reading. Add oil only when the level
is at or below the ADD or MIN mark.
•Check the windshield washer solvent and
add if required.
•Check tire pressure and look for unusual
wear or damage. Rotate tires at the first sign
of irregular wear, even if it occurs before the
oil indicator system turns on.
•Inspect the battery and clean and tighten the
terminals as required.
•Check the fluid levels of coolant reservoir,
automatic transmission, brake master cylin-
der and power steering and fill as needed.
•Check all lights and other electrical items for
correct operation.
