Oil Change Interval
Considerations for the oil change interval include the type of fuel and the engine application. The establishment of an S O S oil analysis program will enable an evaluation of the used oil. The evaluation can be used to determine the oil change interval that is suitable for your specific engine. Change the engine oil when oil analysis determines that the oil has reached the condemning limit.In the absence of oil analysis, change the engine oil according to the interval that is listed in this Operation and Maintenance Manual, "Maintenance Interval Schedule". Consult your Cat dealer for additional information concerning the S O S oil analysis program and oil change intervals.Drain the Oil
Hot oil and components can cause personal injury.Do not allow hot oil or components to contact skin.
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.

Open the oil drain. 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 procedure 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.Fill the Crankcase
Only use oils that are recommended by Caterpillar. For the proper oil to use, refer to this Operation and Maintenance Manual, "Refill Capacities and Recommendations" topic (Maintenance Section).
If the engine is equipped with an auxiliary oil filter system, extra oil must be added when filling the crankcase. If equipped with an auxiliary oil filter system that is not supplied by Caterpillar, follow the recommendations of the OEM.
Engine damage can occur if the crankcase is filled above the "FULL" mark on the oil level gauge (dipstick).An overfull crankcase can cause the crankshaft to dip into the oil. This will reduce the power that is developed and also force air bubbles into the oil. These bubbles (foam) can cause the following problems: reduction of the oil's ability to lubricate, reduction of oil pressure, inadequate cooling, oil blowing out of the crankcase breathers and excessive oil consumption.Excessive oil consumption will cause
