Diesel Engine Oil (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, CD/SF, CE or military specifications MIL-L-2104C or MIL-L-2104D.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.Consult the "EMA Lubricating Oils Data Book," Form SEBU6310, for a listing of oil brands. 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.Hydraulic Oil (HYDO)
Cat Hydraulic Oil should be used to achieve maximum life and performance from hydraulic system components. Use of Cat Hydraulic Oil is recommended in most hydraulics.* 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 are also acceptable.Transmission Oil (TDTO)
Maximum transmission life and performance can be achieved, by using Caterpillar's:* Cat Transmission/Drive Train Oil (TDTO) Failure to follow this recommendation can cause shortened transmission life due to material incapability and inadequate frictional requirements for disk materials.If circumstances require the use of an oil other than Cat Transmission/Drive Train Oil, use an oil that meets API CD/TO-2 or military specification MIL-L-2104D. Multi-grade oils are not blended for use in transmissions. Multi-grade oils which use high molecular weight polymers as viscosity index improvers lose their viscosity effectiveness by permanent and temporary shear of the VI improper.
This oil is formulated for transmissions and drive trains only, and should not be used in engines. Shortened engine life will result.
Final Drive and Differential Oil (GO)
Maximize differential and final drive compartment life, by using Caterpillar's:* Cat Gear Oil (GO)If a lubricant other than Cat Gear Oil must be used, select an oil that meets API classification GL-5 or military specification MIL-L-2105C.Lubricating Grease (MPGM)
Use Multipurpose Molybdenum Grease for all lubrication points. Caterpillar grease will maximize life of Caterpillar equipment, use:* Multipurpose Molybdenum Grease (MPGM)If MPGM grease cannot be used, a multipurpose-type grease which contains 3% to 5% molybdenum disulfide can be used.NLGI No. 2 grade is suitable for most temperatures. Use NLGI No. 1 or No. 0 grade for extremely low temperature.Wheel Coolant Solution (WCS)
Use a 20% ethylene-glycol and 80% water mixture to make an acceptable wheel coolant solution.
