Engine Oils (DEO and EO)
Caterpillar has two oil formulations to provide maximum performance and life in Caterpillar engines.* Cat Diesel Engine Oil (DEO)* Cat Engine Oil (EO)Cat Diesel Engine Oil (DEO) (certified as API 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 and an occasional extended drain period.Cat Engine Oil (EO) is performance rated as:SAE 10W30 - API CF-4 (new category); API CESAE 15W40 - API CF-4 (new category); API CE;API CD-IISAE 30 - API CD-II; API CDThis oil formulation has strong dispersancy effectiveness along with sufficient alkalinity and low sulfated ash level for the performance requirements of the present day engine designs. By meeting the new API CF-4 performance category, requirements are met for newly designed engines of the future.The oil type to be selected will depend on the engine type, fuel sulfur, application and customer preference. But, as a general reference, use the following chart:Commercial Oils
If oils other than Cat oils are to be used, use the following oil specifications as guidelines for the selection of commercial products:* API specification CE, CD, MIL-L-2104E or D and the Cat Micro-oxidation Test* API specification CF-4, CE, CD, or CCMC D4 or D5, or MIL-L-2104E or DOil with these specifications may require shortened oil change intervals as determined by close monitoring of oil condition with Scheduled Oil Sampling (S O S). Consult your Caterpillar dealer.
Failure to follow the oil recommendations can cause shortened engine life due to carbon deposits or excessive wear.
Consult the "EMA Lubricating Oils Data Book", Form SEBU6310, for a listing of oil brands.Additional Notes
The percentage of sulfur in the fuel will affect the engine oil recommendations. For fuel sulfur effects, the Infrared Analysis or 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.The Caterpillar 20 times rule for TBN (Reference: Oil and Your Engine SEBD0640) versus fuel sulfur is a general requirement, but it can be modified by used oil analysis. The effectiveness of an oil formulation will depend on the additive package. A balanced additive package oil of a lower TBN can be as effective in fuel sulfur neutralization and overall performance as some oils with higher TBN values which have additives just for increased TBN. The used oil analysis can show these results.
Failure to follow these recommendations can cause shortened engine life due to carbon deposits or excessive wear.
Always consult with your Caterpillar dealer for the latest lubrication recommendations.Anti-Seize Compound (ASC)
Use 5P3931 Anti-Seize Compound (ASC) or equivalent.Cat Lubricating Grease
Caterpillar has greases for all applications.* Cat Multipurpose Molybdenum Grease (MPGM)Use MPGM for heavily loaded bearings and joints where an extreme pressure grease will maximize the life of Caterpillar equipment. This NLGI No. 2 grade is suitable for most temperatures.If MPGM is not available, use a multipurpose type grease which contains 3 to 5% molybdenum.* 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 175°C (350°F)] 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)This grease is recommended for high temperature anti-friction bearings in such applications as electric motors, alternators, starters and generators. The grease is a NLGI No. 2 grade.This NLGI No. 2 grade is suitable for most temperatures [-28°C to +149°C (-18°F to +300°F)]. Use NLGI No. 1 or No. 0 grade for extremely low temperature.If this grease is not available, use a similar multipurpose grease suitable for anti-friction bearings.
