Note: Decrease the interval between oil changes by 20 percent and/or increase the API service classification of the oil for engines that operate at high load factors of 80 percent or more for extended periods of time. Refer to Caterpillar Publication, PEDP8025, "S O S Fluid Analysis Interpetation Guide" in order to fully understand optimizing oil change intervals.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 filters according to Table 1.

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 method allows proper draining of the waste particles that are suspended in the oil.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.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
Drain the oil according to the equipment on the engine.

(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
