Engine Oil
API Oils
The Engine Oil Licensing and Certification 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.

Typical API symbolDiesel engine oils CC, CD, CD-2, and CE have not been API authorized classifications since 1January 1996. Table 1 summarizes the status of the classifications.
Table 1
API Classifications    
Current     Obsolete    
CI-4 (1)CH-4 (1), CG-4 (2), CF-4 (3)     CE    
CF (4)     CC, CD    
CF-2 (5)     CD-2 (5)    
( 1 ) API CH-4 and CI-4 oils are acceptable if the requirements of Caterpillar's ECF-1 (Engine Crankcase Fluid specification-1) are met. CH-4 and CI-4 oils that have not met the requirements of Caterpillar's ECF-1 Specification 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 classifications for two-cycle diesel engines. Caterpillar does not sell engines that utilize the CD-2 and the API CF-2 oils.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 fill 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 significant 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)Commercial Oils
Engine Crankcase Fluid Recommendations for all current and noncurrent Caterpillar On-highway Diesel Truck Engines:
API CH-4 oils and API CI-4 oils are acceptable if the requirements of Caterpillar's ECF-1 (Engine Crankcase Fluid specification-1) are met. CH-4 oils and CI-4 oils that have not met the requirements of Caterpillar's ECF-1 Specification may cause reduced engine life.
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.
API CF-4 oils are no longer recommended.
In selecting oil for any engine application, both the oil viscosity and oil performance classification/specification as specified by the engine manufacturer must be defined and satisfied. Using only one of these parameters will not sufficently define oil for an engine application.
In order to make the proper choice of a commercial oil, refer to the following explanations:API CI-4 - API CI-4 oils were developed in order to meet the requirements of high performance diesel engines
