General Lubricant Information
Because of government regulations regarding the certification of exhaust emissions from the engine, the lubricant recommendations must be followed.

The Engine Oil Licensing and Certification System by the American Petroleum Institute (API) and the Association des Constructers European Automobilesand (ACRA) 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.

Terminology
Certain abbreviations follow the nomenclature of "SAE J754". Some classifications follow "SAE J183" abbreviations, and some classifications follow the "EMA Recommended Guideline on Diesel Engine Oil". In addition to Caterpillar definitions, there are other definitions that will be of assistance in purchasing lubricants. Recommended oil viscosities can be found in this publication, "Fluid Recommendations/Engine Oil" topic (Maintenance Section).Engine Oil
Commercial Oils
Caterpillar require the use of the following specification of engine oil. Failure to use the appropriate specification of engine oil will reduce the life of your engine. Failure to use the appropriate specification of engine oil will also reduce the life of your aftertreatment system.

Oil Specification
API CK-4
ACEA E9
ECF-3 API CK-4 and ACEA E9 oil categories have the following chemical limits:
0.1 percent maximum sulfated ash
0.12 percent maximum phosphorous
0. 4 percent maximum sulfurThe chemical limits were developed to maintain the expected life of the engine aftertreatment system. The performance of the engine aftertreatment system can be adversely affected if oil that is not specified in table 1 is used.The life of your Aftertreatment system is defined by the accumulation of ash on the surface of the filter. Ash is the inert part of the particulate matter. The system is designed to collect this particulate matter. There is a very small percentage of particulate matter that is left behind as the soot is burnt. This matter will eventually block the filter, causing loss of performance and increased fuel consumption. Most of the ash comes from the engine oil which is gradually consumed during normal operation. This ash is passes through the exhaust. To meet the designed life of the product, the use of the appropriate engine oil is essential. The oil specification that is listed in table 1 has low ash content.Maintenance intervals for engines that use biodiesel - The oil change interval can be adversely affected by the use of biodiesel. Use oil analysis to monitor the condition of the engine oil. Use oil analysis also to determine the oil change interval that is optimum.Note: API FA-4 oil is designed for use in selected on-highway applications and is NOT designed to support off-road applications, including Cat Engines. DO NOT use API FA-4 oil for Cat engines. These engine oils are not approved by Caterpillar and these engine oils must not be used: CC, CD, CD-2, CF-4, CG-4, CH-4, and CI-4.Lubricant Viscosity Recommendations for Direct Injection (DI) Diesel Engines
The correct SAE viscosity grade of oil is determined by the
