oil viscosity CHRYSLER VOYAGER 2004 Service Manual

²Society of Automotive Engineers (SAE)
²American Petroleum Institute (API)
²National Lubricating Grease Institute (NLGI)
API SERVICE GRADE CERTIFIED
Use an engine oil that is API Certified (GF-3).
Mopartprovides engine oils, meeting Material Stan-
dard MS-6395, that meet or exceed this requirement.
SAE VISCOSITY
An SAE viscosity grade is used to specify the vis-
cosity of engine oil. Use only engine oils with multi-
ple viscosities such as 5W-30 or 10W-30. These are
specified with a dual SAE viscosity grade which indi-
cates the cold-to-hot temperature viscosity range.
Select an engine oil that is best suited to your par-
ticular temperature range and variation (Fig. 2).
ENERGY CONSERVING OIL
An Energy Conserving type oil is recommended for
gasoline engines. The designation of ENERGY CON-
SERVING is located on the label of an engine oil con-
tainer.
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 (Fig. 3).
This symbol means that the oil has been certified
by the American Petroleum Institute (API). Diamler-
Chrysler only recommends API Certified (GF-3)
engine oils that meet the requirements of Material
Standard MS-6395. Use Mopartor an equivalent oil
meeting the specification MS-6395.
SYNTHETIC ENGINE OILS
There are a number of engine oils being promoted
as either synthetic or semi-synthetic. If you chose touse such a product, useonlythose oils that meet the
American Petroleum Institute (API) and SAE viscos-
ity standard. Follow the service schedule that
describes your driving type.
ENGINE OIL ADDITIVES/SUPPLEMENTS
The manufacturerdoes not recommendthe addi-
tion of any engine oil additives/supplements to the
specified engine oil. Engine oil additives/supplements
should not be used to enhance engine oil perfor-
mance. Engine oil additives/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 con-
tain undesirable materials that harm the long term
durability of engines by:
²Doubling 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 protect the vehicles emissions perfor-
mance. 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.
²Altering the viscosity characteristics of the
engine oil so that it no longer meets the require-
ments of the specified viscosity grade.
²Creating 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 lubri-
cants. In addition, API classification defines the
lubricants usage. Such as API GL-5 and SAE 75W-
90.

DESCRIPTION - FUEL REQUIREMENTS -
DIESEL ENGINE
WARNING: DO NOT USE ALCOHOL OR GASOLINE
AS A FUEL BLENDING AGENT. THEY CAN BE
UNSTABLE UNDER CERTAIN CONDITIONS AND
HAZARDOUS OR EXPLOSIVE WHEN MIXED WITH
DIESEL FUEL.
Use good quality diesel fuel from a reputable sup-
plier. For most year-round service, number 2 diesel
fuel meeting DIN EN 590 (Class0-4)will provide
good performance. If the vehicle is exposed to
extreme cold (below -18ÉC/0ÉF) or is required to oper-
ate at colder than normal conditions for prolonged
periods, use climatize No. 2 diesel fuel or dilute the
No. 2 diesel fuel with 50% No. 1 diesel fuel as long as
it meets ASTM D 975: 1D and 2D and the quality of
lubrication behavior is in accordance with DIN EN
590. This will provide better protection from fuel gel-
ling or wax plugging of the fuel filters.
Diesel fuel is seldom completely free of water. To
prevent fuel system trouble, including fuel line freez-
ing in winter, drain the accumulated water from the
fuel/water separator using the fuel/water separator
drain provided. If you buy good quality fuel and fol-
low the cold weather advice above, fuel conditioners
should not be required in your vehicle. If available in
your area, a high cetane ªpremiumº diesel fuel may
offer improved cold starting and warm up perfor-
mance.
DESCRIPTION - ENGINE OIL - DIESEL
ENGINES
Use only Diesel Engine Oil meeting standardMIL-
2104Cor API ClassificationCD or higherorCCML
D4, D5.
SAE VISCOSITY GRADE
CAUTION: Low viscosity oils must have the proper
API quality or the CCMC G5 designation.
To assure of properly formulated engine oils, it is
recommended that SAE Grade 10W-40 engine oils
that meet Chrysler material standard MS-6395, be
used in accordance to ACEA B3, B4 specification.
European Grade 10W-40 oils are also acceptable.
Oils of the SAE 5W-40 grade number are preferred
when minimum temperatures consistently fall below
-15ÉC.
DESCRIPTION - AWD REAR DRIVELINE
MODULE FLUIDS
The AWD Rear Driveline Module Assembly consists
of two subassemblies, the Overrunning Clutch Hous-
ing (front) and the Differential Carrier (rear).
The recommended lubricant for the Overrunning
Clutch Housing is MopartATF+4. The recommended
lubricant for the Differential Carrier is Mopart
80W-90 Gear and Axle Lubricant.
