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)SAE 10W30 - API CF-4 (new category); API CE;SAE 15W40 - API CF-4 (new category); API CE;SAE 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 in single viscosity grades (SAE 10W, 30 and 40). Commercial Oils
If oils other than Cat oils are to be used, the following oil specifications provide guidelines for the selection of commercial products.* API specifications CF-4 or CF-4/SGIf API CF-4 oils are not available, the API CE or CE/SG 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 CF-4 or CE performance oils can cause shortened engine life due to piston carbon deposits, liner bore polish and/or abnormally higher increasing oil consumption.
Additional Notes
The percentage of sulfur in the fuel will affect the engine oil recommendations. For fuel sulfur effects, the Infrared Analysis and the ASTM D2896 procedure can be used to evaluate the residual neutralization properties of an engine oil. The sulfur products formation depends on the fuel sulfur content, oil formulation, crankcase blowby, engine operating conditions and ambient temperature.Caterpillar's 20 times rule for TBN (Reference: Oil and Your Engine, SEBD0640) versus fuel sulfur is a general requirement which was developed in the early 1980's for Cat prechamber combustion (PC) system engines with the oil formulation of that era. The fuel sulfur neutralization of today's new oil formulations along with direct injection (DI) system engines are more effective.Field results indicate that direct injection combustion (DI) systems and the oils now recommended for these engines will operate at an oil TBN equal to 10 times the fuel sulfur. Caterpillar requirements will reflect this new value of 10 times instead of 20 times for oil TBN when related to fuel sulfur for Cat DI engines and API CF-4 oils.For more information on oil and fuel sulfur content, refer to Oil and Your Engine, SEBD0640 and for a listing of oil brands refer to EMA Lubricating Oils Data Book, SEBU6310.Anti-Seize Compound (ASC)
* Use 6V4876 Molykote paste lubricant or equivalent. Typical use: head bolt threads and washers.* Use 5P3931 Anti-Seize Compound (ASC) or equivalent. Typical use: exhaust manifold studs and nuts.Cat Lubricating Grease
Caterpillar has greases for all applications.* Cat Multipurpose Lithium Grease (MPGL) (non-extreme pressure). This NLGI No. 2 grade is recommended for light duty automotive type applications where a high temperature [up to 350°F (175°C)] is required. This grease offers excellent mechanical stability, high resistance to oxidation, good rust protection and excellent breakaway torque. If this grease is not available, use a similar multipurpose grease.* Cat Special Purpose Grease (SPG). Use Special Purpose-type Grease (SPG) suitable for taper roller bearings which operate at high speeds and temperatures for lubricating engine fan drive bearing. This grease conforms to MIL-M-7866 and contains a suitable corrosion inhibitor. NLGI No. 2 Grade is suitable for most temperatures.This NLGI No. 2 grade is suitable for most temperatures [-18° to +300°F (-28° to + 149°C)]. Use NLGI No. 1 or No. 0 grade for extremely low temperature. Caterpillar part number 2S3230 (standard cartridge) meets these specifications. It is acceptable for temperatures from -30° to 325°F (-35° to 160°C).If this grease is not available, use a similar multipurpose grease suitable for anti-friction bearings.Always consult with your Caterpillar dealer for the latest lubrication recommendations.
