Lubricating Oil Recommendations and Specifications
General Information
CAUTION
The fuel sulphur content should not exceed 0.5 mass percent sulphur. If the fuel sulphur content is greater
than 0.5 mass percent sulphur, seek advice from your local Cummins® Distributor. For recommendations of
fuel for Cummins® engines, refer to Fuel for Cummins® Engines, Bulletin 3379001.
CAUTION
Extending the oil and filter change interval beyond the recommendations will decrease engine life due to
factors such as corrosion, deposits and wear.
CAUTION
Cummins Inc. does not recommend the use of A.C.E.A. E4/MB 228.5 formulation oils, which do not attain one
or more of the following lubricant qualifications: A.P.I. CH-4. CI-4, A.C.E.A. E5. E7, C.E.S. 20071, C.E.S. 20072,
C.E.S. 20076, C.E.S. 20077, C.E.S. 20078. If A.C.E.A. E4/MB 228.5 formulation oils, which do not comply with
the oil specifications listed above, are used in Cummins® automotive engines, problems such as wear to
overhead, sliding tappets, camshaft and crankshaft bearings may be experienced.
The use of quality engine lubricating oils, combined with appropriate oil drain and filter change intervals, is a critical
factor in maintaining engine performance and durability. Extending the oil and filter change interval beyond the
recommendations will decrease engine life due to factors such as corrosion, deposits and wear.
NOTE: The responsibility is with the owner. If recommendations are ignored, warranty could be affected.
NOTE: A.C.E.A. = Association des Constructeurs Européen d'Automobiles, A.P.I. = American Petroleum Institute and
C.E.S. = Cummins® Engineering Standard.
Cummins Inc. recommends the use of a high-quality SAE 15W-40 heavy-duty engine oil, such as Valvoline Premium
Blue™, which meets or exceeds the American Petroleum Institute (API) performance classification CH-4/SJ or CI-4/
SK and the Association des Constructeurs Européen d'Automobiles (A.C.E.A.) performance classification E5 or E7.

1. CG-4/SH and E-3 oils can be used in areas where none of the recommended oils are available, but the oil drain
interval must be reduced by one half of the interval given in the maintenance schedule. See the oil drain interval
information in Section 2.
A sulfated ash limit of 1.0 mass percent is suggested for optimum valve and piston deposit, and oil consumption
control. The sulfated ash must not exceed 1.85 mass percent.
Special “break-in” oils are not recommended for use in new or rebuilt Cummins® engines. Use the same lubricating oil
that will be used in normal engine operations.
Use of "synthetic engine oils" (those made with API group 3 or group 4 base stocks) is permitted subject to the same
performance and viscosity limitations of petroleum (mineral) based engine oils. The same oil change intervals must be
applied to synthetic oils that are applied to petroleum (mineral) based engine oils.
For further details and discussion of engine lubricating oils for Cummins® engines, refer to Cummins® Engine Oil
Recommendations, Bulletin 3810340.
