C175-16Engine Oil Change Interval
Sump Configuration Interval
Standard Every 1000 hours The S O S oil analysis program analyzes used oil to determine if the oil change interval is suitable for your specific engine.Drain the Engine 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 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: The threads that are provided on the drain valve are metric. Drain the oil into a suitable container. Dispose of the oil according to local regulations.

Oil drain plug (1) may be used to drain the oil. After the oil has drained, close the oil drain and/or reinstall the drain plug.
If a suction device is inserted into the oil pan, ensure that the suction device is clean. 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.Replace Oil Filter Elements
