The oil change interval will be affected by the following items:
Engine application
Size of the oil sump
Fuel type
Oil type
Ambient air conditions
Air/fuel ratioThe S O S oil analysis program analyzes used oil 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 .
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact the skin.
Drain the Oil
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. Cleaning the suction device 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.
If the oil drain valve has a “quick connect” coupling, attach the coupling. Open the drain valve to drain the crankcase. After the oil has drained, close the drain valve. Disconnect the coupling.
Replace the engine oil filter elements before you fill the crankcase with new oil.Replace the Oil Filter Elements
Replace the engine oil filters when any of the following conditions occur:
Every oil change
The engine oil filter differential pressure reaches 103 kPa (15 psi).Note: Do not attempt to clean the used oil filters. Used oil filters will retain waste particles. The used oil filters would not filter the oil properly.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,
