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 oils that do not contain viscosity improvers. The MIL specifications are U.S.A. Military Specifications. The CCMC refers to an organization of major European manufacturers engine oil performance specifications. Recommended oil viscosities can be found in the Lubricant Viscosities chart.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 Lubricant Specification
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. Caterpillar Oils are formulated to provide maximum performance and life in your Caterpillar engine. They are offered in multi-viscosity grades to meet the performance and ambient temperature requirements for heavy duty diesel engines.Caterpillar Oil
To achieve the maximum engine life and superior performance in your Caterpillar diesel engine, Caterpillar recommends Caterpillar Diesel Engine Oil-DEO (API CG-4). Oils meeting the American Petroleum Institute (API CG-4) performance category possess the properties to operate effectively at the higher piston temperatures.Caterpillar Oils are currently offered by Caterpillar dealers for continued refill use. Consult your Caterpillar dealer for more information on Caterpillar Oils.The DEO (CG-4) oil is blended in viscosity grades of SAE 10W30 and 15W40. Multi-grade oils significantly lower oil consumption compared to single grades. Oil consumption and piston crown land deposits are very important in the engine tests used to evaluate oil performance.Commercial Oils
If oils other than Caterpillar oils are to be used, the following oil specifications provide guidelines for the selection of commercial products.* API specifications CG-4, CG-4/SH, CF-4, CF-4/SF, or CF-4/SGIf API CG-4 or CF-4 oils are not available, the API CE, CE/SF, CE/SG, or CCMC D4 or MIL-L-2104E may be used with shortened oil change intervals as determined by close monitoring of oil condition with Scheduled Oil Sampling (S O S) and infrared analysis.
Failure to follow the commercial oil recommendation for API CG-4 performance oils can cause shortened engine life due to piston carbon deposits, liner bore polish and/or abnormally higher increasing oil consumption.API CC and CD oils are unacceptable in this Caterpillar diesel engine.

Lubricant Viscosity Recommendations
The recommendations refer only to the SAE viscosity grade for the expected ambient temperature range. The required performance criteria for the oils are defined in this section. The proper SAE grade of oil to select is determined by the minimum outside temperature at which the engine will be started and the maximum outside temperature in which the engine will be operating. This recommendation is to ensure the correct viscosity is used until the next oil change.The use of API CG-4 multi-viscosity oils is recommended because of full protection through a wider temperature range. The recommendation would be to use the highest viscosity oil possible. Even though the ambient temperature may be low, operating engines can still be subjected to normal
