2007 Ram 2500 (Diesel) oil viscosity

2. Engine Oil Viscosity (SAE Grade)
The proper SAE viscosity of engine oil for the expected
ambient temperature range should be selected, as indi-
cated in the following chart:
NOTE:The same oil change interval is to be followed
for synthetic oil as for petroleum based oil. Also, syn-
thetic oil must meet the same performance specifications
as petroleum oil.
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.

Engine Oil Selection (6.7L Diesel Engines)
For best performance and maximum protection under all
types of operating conditions, the manufacture only
recommends engine oils that are API CJ-4 certified and
meet the requirements of DaimlerChrysler. Use Mopar or
an equivalent oil meeting the specification MS-10902.
Products meeting Cummins CES 20081 may also be used.
The identification of these engine oils are typically lo-
cated on the back of the oil container.
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 manufacture
only recommends API Certified en-
gine oils.Oils with a high ash content may produce deposits on
valves that can progress to guttering and valve burning.
A maximum sulfated ash content of 1.00 mass % is
recommended for all oil used in the engine.
The same oil change interval is to be followed for
synthetic oil as for petroleum based oil. Also, synthetic oil
must meet the same performance specifications as petro-
leum oil.
Engine Oil Viscosity (SAE Grade)
Use SAE 15W-40 Engine Oil that meets
DaimlerChrysler Materials Standard MS-10902 and the
API CJ-4 engine oil category.
Engine oil not designated by the DaimlerChrysler or
Cummins Material Standards and API CJ-4 should not be
used, engine and exhaust system durability may be
compromised. For lower temperature operation SAE
5W-40 engine oils may be used. These oils must meet the
