2014 JEEP GRAND CHEROKEE oil viscosity

WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Mon-
oxide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious in-
jury or death when inhaled.
• Keep Remote Keyless Entry (RKE) transmitters
away from children. Operation of the Remote Start
System, windows, door locks or other controls
could cause serious injury or death.
ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due
to its construction. Normal operation is allowed, provid-
ing the following recommendations are followed:
• Warm up the engine before placing it under load.
•
Do not operate the engine at idle for prolonged periods.
• Use the appropriate transmission gear to prevent
engine lugging.
•
Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carry-
ing or towing significant weight.
NOTE: Light duty operation such as light trailer towing
or no load operation will extend the time before the
engine is at full efficiency. Reduced fuel economy and
power may be seen at this time.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil changes
should be consistent with anticipated climate conditions
under which vehicle operations will occur. The recom-
mended viscosity and quality grades are shown under
“Fluids, Lubricants and Genuine Parts”, under “Maintain-
ing Your Vehicle” in this manual. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE USED.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 7

NOTE:
•Use of Climatized Ultra Low Sulfur Diesel Fuel or
Number 1 Ultra Low Sulfur Diesel Fuel results in a
noticeable decrease in fuel economy.
• Climatized Ultra Low Sulfur Diesel Fuel is a blend of
Number 2 Ultra Low Sulfur and Number 1 Ultra Low
Sulfur Diesel Fuels which reduces the temperature at
which wax crystals form in fuel.
• The fuel grade should be clearly marked on the pump
at the fuel station.
• The engine requires the use of “Ultra Low Sulfur
Diesel Fuel”. Use of incorrect fuel could result in
engine and exhaust system damage. Refer to “Fuel
Requirements” in “Starting And Operating” for fur-
ther information.Engine Oil Usage
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for the correct engine oil viscosity.
Engine Warm-Up
Avoid full throttle operation when the engine is cold.
When starting a cold engine, bring the engine up to
operating speed slowly to allow the oil pressure to
stabilize as the engine warms up.
If temperatures are below 32°F (0°C), operate the engine
at moderate speeds for five minutes before full loads are
applied.
Engine Idling
Avoid prolonged idling, long periods of idling may be
harmful to your engine because combustion chamber
temperatures can drop so low that the fuel may not burn
completely. Incomplete combustion allows carbon and
40 STARTING AND OPERATING

Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Add oil
only when the level on the dipstick is below the “MIN”
mark. The total capacity from the MIN mark to the MAX
mark is 1.7 qts (1.6L).
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.
NOTE: It is possible for your oil level to be slightly
higher than a previous check. This would be due to diesel
fuel that may temporarily be in the crankcase due to
operation of the diesel particulate filter regeneration
strategy. This fuel will evaporate out under normal
operation. Never operate the engine with oil level below the “MIN”
mark or above the upper “MAX” mark.
Change Engine Oil
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Engine Oil Viscosity (SAE Grade)
CAUTION!
Your vehicle is equipped with an advanced technol-
ogy Diesel Engine and an emission device designed
to limit Diesel Particulate Emissions from being
released into the atmosphere. The durability of your
engine and life expectancy of this diesel particulate
filter emission device is highly dependent on the use
of the correct engine oil.
