LEVER AS 1141803 - Caterpillar

If the engine is equipped with duplex oil filters, the engine oil filter elements can be changed while the engine is in operation. This feature is useful if the oil filter elements require more frequent replacement than the engine oil. Refer to "Replacing the Engine Oil Filters During Engine Operation".The oil change interval can be affected by several factors:
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 the interval that is listed in 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, 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.
Drain the oil according to the equipment on the engine. Note: Drain the oil into
