Hot oil and components can cause personal injury.Do not allow hot oil or components to contact skin.
The oil change interval will be affected by the following items:
Air/fuel ratio
Ambient air conditions
Engine application
Fuel type
Oil type
Size of the oil sumpThe S O S oil analysis program analyzes used oil in order to determine if the oil change interval is suitable for your specific engine. In the absence of S O S oil analysis, change the engine oil and engine oil filters according to the interval that is listed in Table 1.

Do not drain the oil when the engine is cold. As the oil cools, suspended waste particles settle on the bottom of the oil pan. The waste particles are not removed when the cold oil is drained. Drain the crankcase when the oil is warm. This draining method allows the waste particles that are suspended in the oil to be drained properly.Failure to follow this recommended procedure will allow the waste particles to be recirculated through the engine lubrication system with the new oil.
After the engine has been operated at normal operating temperature, STOP the engine.
Drain the oil according to the equipment on the engine.Note: Drain the oil into a suitable container. Dispose of the oil according to local regulations.

(1) Oil drain
Open oil drain (1). After the oil has drained, close the oil drain.
If a suction device is inserted into the oil pan, ensure that the suction device is clean. This will prevent dirt from entering into the oil pan. Be careful not to strike the engine oil suction tubes or the piston cooling jets.
If a suction device that attaches to the oil drain is used, ensure that the suction device is clean. Attach the suction device to the oil drain. Open the oil drain. After the oil has drained, close the oil drain and remove the suction device.Replace the Oil Filter Elements
Replace the engine oil filters when either of the following conditions are met:
Every oil change
The engine oil filter differential pressure reaches 103 kPa (15 psi).Service tools are available to aid in the service of oil filters. Consult your Caterpillar dealer for the part names and the part numbers. Follow the instructions that are supplied with the service tools. If the service tools are not used, perform the following appropriate procedure.
