Lubricant Information
Certain abbreviations follow Society of Automotive Engineers (SAE) J754 nomenclature and some classifications follow SAE J183 abbreviations. SPC is a Caterpillar designation for special synthetic base stock oils that do not contain viscosity improvers. 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 Manual.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.Engine oil performs several basic functions in order to provide adequate lubrication. It keeps the engine clean and free from rust and corrosion, acts as a coolant, and reduces friction and wear by minimizing metal-to-metal contact.Engine Lubricant Specification
The performance characteristics of the oil depends on the base oil and the additives. The additives in the oil will vary according to the properties of the base oil and the environment in which the oil will perform its function.Maximum engine life and performance can be expected when the proper engine oil is used. There are significant variations in the quality and performance of the oils commercially available. To achieve the maximum engine life and superior performance in your diesel engine, Caterpillar recommends the following.* API CF-4 (engine oil)* Caterpillar Diesel Engine Oil-DEO (CF-4)Caterpillar Oils have been developed, tested and approved by Caterpillar to provide the performance and life which has been designed and built into our engines. Caterpillar Oils are currently being used for engine lab development and are offered by Caterpillar dealers for continued use. Consult your Caterpillar dealer for more information on these Caterpillar Oils.Caterpillar Oils are offered in multi-viscosity grades to meet the performance and ambient temperature requirements. Caterpillar Oils are performance rated as SAE 10W30 - API CF-4 and SAE 15W40 - API CF-4.Caterpillar 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. 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 crown land deposits are very important in the engine tests used to evaluate oil performance. A new oil category is now under developed (at the time of publication) which will upgrade the oil performance beyond API CF-4. The new oil will replace CF-4 when it becomes available. See your Caterpillar dealer for information.Engine Lubricant Viscosity Recommendations
The proper SAE grade of oil to select is determined by the minimum outside temperature at which
