5-3.1.1 Engine Oil
API Oils
The Engine Oil Licensing and Certifi cation System by the American Petroleum Institute
(API) is recognized by Caterpillar. For detailed information about this system, see the
latest edition of the “API publication No. 1509”. Engine oils that bear the API symbol
are authorized by API.
Diesel engine oils, CC, CD, CD-2, and CE have not been API authorized classifi cations
since January 1, 1996. The API Classifi cation Table that follows summarizes the
status of the classifi cations.

(1) API-CH-4 and CI-4 oils are acceptable if the requirements of Caterpillar’s ECF-1 (Engine Crankcase
Fluid specifi cations-1) are met. CH-4 and CI-4 oils that have not met the requirements of Caterpillar’s
ECF-1 Specifi cation may cause reduced engine life.
(2) API CG-4 oils are acceptable for all Caterpillar diesel engines. When the API CG-4 oils are used, the
oil drain interval should not exceed 75 Percent of the standard oil drain interval for your engine.
(3) API CF-4 oils are no longer recommended for Caterpillar on-highway diesel engines.
(4) API CF oils are not recommended for Caterpillar on-highway diesel engines.
(5) API CF-2 and CD-2 oils are classifi cations for two-cycle diesel engines. Caterpillar does not sell
engines that utilize the CD-2 and the API CF-2 oils.
5-3.1.2 Caterpillar Diesel Engine Oil (DEO)
Caterpillar Oils have been developed and tested in order to provide the full performance and service life that has been designed and built
into Caterpillar Engines. Caterpillar Oils are currently used to fi ll diesel engines at the factory. These oils are offered by Caterpillar dealers
for continued use when the engine oil is changed. Consult your Caterpillar dealer for more information on these oils.
Due to signifi cant variations in the quality and in the performance of commercially available oils, Caterpillar makes the following
recommendations:
Caterpillar Diesel Engine Oil (DEO) (10W-30)
Caterpillar Diesel Engine Oil (DEO) (15W-40)
