COIL 1636512 - Caterpillar

General Information
Certain abbreviations follow S.A.E. J754 nomenclature and some classifications follow S.A.E. J183 abbreviations. The MIL specifications are U.S.A. Military Specifications. 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.Diesel Engine Oils (DEO)
Caterpillar has two engine oils. To achieve the maximum engine life and performance in your diesel engines. Caterpillar's first recommendation is:* CAT Diesel Engine Oil (DEO)CAT Diesel Engine Oil is specially formulated for Caterpillar Diesel Engines, to reduce piston and ring deposits and thus provide longer engine life and stable oil control.Engine Oil (EO)
CAT Engine Oil is Caterpillar's second recommendation for an engine oil specifically intended for use in mixed fleets. This oil is only for the convenience of having the same oil for gasoline and diesel engines.For mixed fleet convenience, use Caterpillar's:* CAT Engine Oil (EO)If circumstances require the use of an oil other than the CAT Diesel Engine Oil or CAT Engine Oil, the following oil specifications can be used; European oil specification CCMC D3, API specification CD, CE, CD/SF or military specifications MIL-L-2104D or MIL-L-2104E.Oil 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. The percentage of sulfur in the fuel will affect the engine oil recommendations. If the fuel has over 0.5% sulfur, the engine oil must have a Total Base Number (TBN) of twenty times the percentage of fuel sulfur (TBN as measured by the ASTM D2896 method). When operating with a fuel sulfur above .7%, (CAT Diesel Engine Oil is a 14 TBN oil), consult with your Caterpillar dealer for an engine oil that has a higher TBN.For more information on oil and fuel sulfur content, refer to "Oil and Your Engine", Form SEBD0640.
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.Final Drive and Differential Oil (TDTO)
For maximum life and performance of the differential and final drive components, select the correct viscosity of Caterpillar's:* CAT Transmission/Drive Train Oil (TDTO)If circumstances require the use of an oil other than CXP, use an API classification CD/TO-2 or MIL-L-2104D.Hydraulic Oil (HYDO)
CAT Hydraulic Oil should be used to achieve maximum life and performance from hydraulic system components and hydrostatic transmissions. Use of CAT Hydraulic Oil is recommended in most hydraulic and hydrostatic systems.* CAT Hydraulic Oil (HYDO)If different viscosities are required because of extreme ambient temperatures, the following oils can be used, use Caterpillar's:* CAT Engine Oil (EO)* CAT Diesel Engine Oil (DEO)If CAT Hydraulic Oil or Engine Oil is not available, use an engine oil that meets one of these API service classifications; CC, CC/SF, CD or CE. Any military specification of MIL-L-2104 oils can also be used.Industrial-type hydraulic oils that are certified by the oil supplier to have antiwear, antifoam, antirust and antioxidation additives for heavy duty use
