API SERVICE GRADE CERTIFIED

Use an engine oil that is API Certified. MOPAR

provides engine oils, that meet or exceed this requirement.

SAE VISCOSITY

An SAE viscosity grade is used to specify the viscosity
of engine oil. Use only engine oils with multiple viscos-
ities such as 5W-30 or 10W-30. These are specified
with a dual SAE viscosity grade which indicates the
cold-to-hot temperature viscosity range. For 3.7L/4.7L
engines SAE 5W-30 engine oil is recommended for
all operating temperatures. For 5.7L engines, SAE
5W-20 engine oil is recommended for all operating
temperatures. Vehicles with 5.7L engines equipped
with Multiple Displacement System, (MDS), must
use SAE 5W-20 oil. Failure to do so may result in
improper operation of the Multiple Displacement
System (MDS).These engine oils improve low tem-
perature starting and vehicle fuel economy. Refer
to your engine oil filler cap for the recommended engine oil viscosity for your vehicle.

ACEA Categories

For countries that use the ACEA European Oil Categories for Service Fill Oils, use engine oils that meet the require-
ments of ACEA A1/B1, A2/B2, or A3/B3.

ENERGY CONSERVING OIL

An Energy Conserving type oil is recommended for gasoline engines. The designation of ENERGY CONSERVING
is located on the label of an engine oil container.

CONTAINER IDENTIFICATION

Standard engine oil identification notations have been
adopted to aid in the proper selection of engine oil.
The identifying notations are located on the front label
of engine oil plastic bottles and the top of engine oil
cans.

This symbol means that the oil has been certified by
the American

Petroleum

Institute

(API).

Diamler-

Chrysler only recommend API Certified engine oils.
Use Mopar

engine oil or equivalent.

SYNTHETIC ENGINE OILS

There are a number of engine oils being promoted as either synthetic or semi-synthetic. If you chose to use such
a product, use only those oils that meet the American Petroleum Institute (API) and SAE viscosity standard. Follow
the service schedule that describes your driving type.

ENGINE OIL ADDITIVES/SUPPLEMENTS

The manufacturer does not recommend the addition of any engine oil additives/supplements to the specified
engine oil. Engine oil additives/supplements should not be used to enhance engine oil performance. Engine oil addi-
tives/supplements should not be used to extend engine oil change intervals. No additive is known to be safe for
engine durability and can degrade emission components. Additives can contain undesirable materials that harm the
long term durability of engines by:

•

Doubling the level of Phosphorus in the engine oil. The ILSAC (International Lubricant Standard Approval
Committee) GF-2 and GF-3 standards require that engine oil contain no more than 0.10% Phosphorus to pro-
tect the vehicles emissions performance. Addition of engine oil additives/supplements can poison, from the
added sulfur and phosphorus, catalysts and hinder efforts to guarantee emissions performance to 80,000
miles.

•

Altering the viscosity characteristics of the engine oil so that it no longer meets the requirements of the spec-
ified viscosity grade.

•

Creating potential for an undesirable additive compatibility interaction in the engine crankcase. Generally it is
not desirable to mix additive packages from different suppliers in the crankcase; there have been reports of
low temperature engine failures caused by additive package incompatibility with such mixtures.

GEAR LUBRICANTS

SAE ratings also apply to multigrade gear lubricants. In addition, API classification defines the lubricants usage.
Such as API GL-5 and SAE 75W-90.

ENGINE COOLANT

ETHYLENE-GLYCOL MIXTURES

CAUTION: Richer antifreeze mixtures cannot be measured with normal field equipment and can cause prob-
lems associated with 100 percent ethylene-glycol.

The required ethylene-glycol (antifreeze) and water mixture depends upon the climate and vehicle operating condi-
tions. The recommended mixture of 50/50 ethylene-glycol and water will provide protection against freezing to -37°
C (-35° F). The antifreeze concentration must always be a minimum of 44 percent, year-round in all climates. If
percentage is lower than 44 percent, engine parts may be eroded by cavitation, and cooling system com-
ponents may be severely damaged by corrosion. Maximum protection against freezing is provided with a 68
percent antifreeze concentration, which prevents freezing down to -67.7° C (-90° F). A higher percentage will freeze
at a warmer temperature. Also, a higher percentage of antifreeze can cause the engine to overheat because the
specific heat of antifreeze is lower than that of water.

LUBRICATION & MAINTENANCE

Use of 100 percent ethylene-glycol will cause formation of additive deposits in the system, as the corrosion inhibitive
additives in ethylene-glycol require the presence of water to dissolve. The deposits act as insulation, causing tem-
peratures to rise to as high as 149° C (300° F). This temperature is hot enough to melt plastic and soften solder.
The increased temperature can result in engine detonation. In addition, 100 percent ethylene-glycol freezes at 22°
C (-8° F ).

PROPYLENE-GLYCOL MIXTURES

It’s overall effective temperature range is smaller than that of ethylene-glycol. The freeze point of 50/50 propylene-
glycol and water is -32° C (-26° F). 5° C higher than ethylene-glycol’s freeze point. The boiling point (protection
against summer boil-over) of propylene-glycol is 125° C (257° F ) at 96.5 kPa (14 psi), compared to 128° C (263°
F) for ethylene-glycol. Use of propylene-glycol can result in boil-over or freeze-up on a cooling system designed for
ethylene-glycol. Propylene glycol also has poorer heat transfer characteristics than ethylene glycol. This can
increase cylinder head temperatures under certain conditions.

Propylene-glycol/ethylene-glycol Mixtures can cause the destabilization of various corrosion inhibitors, causing dam-
age to the various cooling system components. Also, once ethylene-glycol and propylene-glycol based coolants are
mixed in the vehicle, conventional methods of determining freeze point will not be accurate. Both the refractive index
and specific gravity differ between ethylene glycol and propylene glycol.

HOAT COOLANT

WARNING: ANTIFREEZE IS AN ETHYLENE-GLYCOL BASE COOLANT AND IS HARMFUL IF SWALLOWED OR
INHALED. IF SWALLOWED, DRINK TWO GLASSES OF WATER AND INDUCE VOMITING. IF INHALED, MOVE
TO FRESH AIR AREA. SEEK MEDICAL ATTENTION IMMEDIATELY. DO NOT STORE IN OPEN OR UNMARKED
CONTAINERS. WASH SKIN AND CLOTHING THOROUGHLY AFTER COMING IN CONTACT WITH ETHYLENE-
GLYCOL. KEEP OUT OF REACH OF CHILDREN. DISPOSE OF GLYCOL BASE COOLANT PROPERLY, CON-
TACT YOUR DEALER OR GOVERNMENT AGENCY FOR LOCATION OF COLLECTION CENTER IN YOUR
AREA. DO NOT OPEN A COOLING SYSTEM WHEN THE ENGINE IS AT OPERATING TEMPERATURE OR HOT
UNDER PRESSURE, PERSONAL INJURY CAN RESULT. AVOID RADIATOR COOLING FAN WHEN ENGINE
COMPARTMENT RELATED SERVICE IS PERFORMED, PERSONAL INJURY CAN RESULT.

CAUTION: Use of Propylene-Glycol based coolants is not recommended, as they provide less freeze pro-
tection and less corrosion protection.

The cooling system is designed around the coolant. The coolant must accept heat from engine metal, in the cylinder
head area near the exhaust valves and engine block. Then coolant carries the heat to the radiator where the tube/
fin radiator can transfer the heat to the air.

The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion protection.
Mopar

Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769), or the equivalent ethylene-glycol base coolant

with organic corrosion inhibitors (called HOAT, for Hybrid Organic Additive Technology) is recommended. This cool-
ant offers the best engine cooling without corrosion when mixed with 50% ethylene-glycol and 50% distilled water to
obtain a freeze point of -37°C (-35°F). If it loses color or becomes contaminated, drain, flush, and replace with fresh
properly mixed coolant solution.

CAUTION: Mopar

Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769) may not be mixed with any

other type of antifreeze. Mixing of coolants other than specified (non-HOAT or other HOAT), may result in
engine damage that may not be covered under the new vehicle warranty, and decreased corrosion protec-
tion.

COOLANT PERFORMANCE

The required ethylene-glycol (antifreeze) and water mixture depends upon climate and vehicle operating conditions.
The coolant performance of various mixtures follows:

Pure Water- Water can absorb more heat than a mixture of water and ethylene-glycol. This is for purpose of heat
transfer only. Water also freezes at a higher temperature and allows corrosion.

100 percent Ethylene-Glycol - The corrosion inhibiting additives in ethylene-glycol need the presence of water to
dissolve. Without water, additives form deposits in system. These act as insulation causing temperature to rise to as
