Lubricant Information
Certain abbreviations follow Society of Automotive Engineers (SAE) J754 nomenclature and some classifications follow SAE J183 abbreviations. The MIL specifications are U.S.A. Military Specifications. The CCMC refers to an organization of major European manufacturers responsible for defining engine oil performance specifications. The definitions other than Caterpillar's will be of assistance in purchasing lubricants. Recommended oil viscosities can be found in the Lubricant Viscosities chart in this publication.Grease is classified by the National Lubricating Grease Institute (NLGI) based on ASTM D217-68 Worked Penetration characteristics which are given a defined consistency number.A new oil performance category has been released by the American Petroleum Institute (API) for the diesel engine oil and by Caterpillar for engine oil. The new category is:* API CF-4 (engine oil)The API CF-4 has become the new category for the API CE type oils. The performance tests for this oil will be the new Cat 1K single cylinder oil test engine and other engine tests which are presently part of the CE oil evaluation.Engine Lubricant Specification
Caterpillar has an oil formulation to provide maximum performance and life for your on-highway diesel truck engine. Cat Engine Oils are offered in a full line of appropriate single and multi-viscosity grades to meet the performance and ambient temperature requirements for heavy duty diesel truck engines.Caterpillar recommends the following specifications to achieve the maximum engine life and performance with your on-highway diesel truck engine.* Caterpillar Engine Oil Cat Diesel Engine Oil-DEO (CF-4)Cat Diesel Engine Oil-DEO (CD)Cat Oils are performance rated as SAE 10W30 - API CF-4 (new category); API CE;SAE 15W40 - API CF-4 (new category); API CE;API CD-IISAE 30 - API CD-II; API CDCat Engine Oil is currently being used for factory fill for engines and is offered by Caterpillar dealers for continued refill use. Consult your Caterpillar dealer for this Cat Oil.Cat Diesel Engine Oil DEO (CF-4) is an oil formulated with strong dispersancy effectiveness along with sufficient alkalinity and low sulfated ash level for performance requirements of engine operation in today's and future designs. Oils meeting the American Petroleum Institute (API) CF-4 performance category possess the properties to operate effectively at the higher piston temperatures of some current and future engines.The DEO (CF-4) oil type to be selected will depend on the engine type, fuel sulfur, application and customer preference.The DEO (CF-4) oil is blended in viscosity grades of SAE 10W30 and 15W40. Multi-grade oils are required because of the significantly lower oil consumption of multi-viscosity oils as compared to single grades. Oil consumption and piston crownland deposits are very important in the engine tests used to evaluate oil performance. This oil is also qualified as API SG which allows its use in gasoline engine applications requiring this performance rating.Cat Diesel Engine Oil DEO (CD) is blended with a diesel engine type additive with strong detergency effectiveness. This oil has a higher alkalinity (13.5 TBN) than many oils for the neutralization of wear causing combustion products and provides additional protection for higher fuel sulfur. This oil is blended
