Lubricant Information
Certain abbreviations follow S.A.E. J754 nomenclature and some classifications follow S.A.E. J183 abbreviations. The definitions other than Caterpillar's will be of assistance in purchasing lubricants. The recommended oil viscosities can be found in the Lubricant Viscosities chart in this publication.The grease is classified by the National Lubricating Grease Institute (NLGI) based on the ASTM D217-68 Worked Penetration characteristics which are given a defined consistency number.Engine Oil (EO)
Caterpillar has an oil formulation to provide maximum performance and life in your truck engine.* Cat Engine Oil (EO)Cat Engine Oil (EO) is a lubricant that meets the performance requirements of today's newer truck engines as well as meeting the needs of earlier built truck engines. This oil has sufficient TBN and sulfated ash level to be effective in operation.This lubricating oil also meets the industry standards for both diesel and gasoline engine requirements.* Cat Diesel Engine Oil (DEO)Cat Diesel Engine Oil (DEO) may be used for current truck engines also. DEO provides the required performance for 3406B truck engines, however, it does not meet the API CE performance.Alternate Oils
Failure to follow these recommendations for CE performance oils can cause shortened engine life due to carbon deposits or excessive wear.
If an oil other than Cat oil is to be used, the following oil specifications provide selection guidelines: * API specifications CE, CE/SF, or CE/SGOil with these specifications may require shortened oil change periods as determined by close monitoring of oil condition with Scheduled Oil Sampling (S*O*S) and infrared analysis.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.The Caterpillar 20 times rule for TBN 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.Consult the EMA Lubricating Oils Data Book, form SEBU6310 for a listing of oil brands meeting the CE requirements.For more information on oil and fuel sulfur content, refer to "Oil and Your Engine," form SEBD0640.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 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
