2019 JEEP GRAND CHEROKEE LIMITED oil viscosity

WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
ENGINE BREAK-IN RECOMMENDATIONS — 3.6L &
5.7L ENGINES
A long break-in period is not required for the drivetrain
(engine, transmission, clutch, and rear axle) in your new
vehicle.
Drive moderately during the first 300 miles (500 km). After
the initial 60 miles (100 km), speeds up to 50 or 55 mph (80
or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
However, wide-open throttle acceleration in low gear can
be detrimental and should be avoided.The engine oil, transmission fluid, and axle lubricant
installed at the factory is high-quality and energy-
conserving. Oil, fluid, and lubricant changes should be
consistent with anticipated climate and conditions under
which vehicle operations will occur. For the recommended
viscosity and quality grades, refer to “Fluids And Lubri-
cants” in
Technical Specifications”.

The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to the “Engine Compart-
ment” illustration in this section.
Lubricants which do not have both the engine oil certifi-
cation mark and the correct SAE viscosity grade number
should not be used.
Engine Oil Viscosity (SAE Grade) — 5.7L Engine
Mopar SAE 5W-20 engine oil approved to FCA Material
Standard MS-6395 such as Pennzoil, Shell Helix or equiva-
lent is recommended for all operating temperatures. This
engine oil improves low temperature starting and vehicle
fuel economy.
The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to the “Engine Compart-
ment” illustration in this section.
NOTE:Vehicles equipped with a 5.7L engine must use SAE
5W-20 oil. Failure to do so may result in improper opera-
tion of the Fuel Saver Technology. Refer to “Fuel Saver
Technology – If Equipped” in “Starting And Operating” for
further information. Lubricants which do not have both the engine oil certifi-
cation mark and the correct SAE viscosity grade number
should not be used.
Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes are
followed.
Synthetic engine oils which do not have both the engine oil
certification mark and the correct SAE viscosity grade
number should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to the
engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental additives.
