Engine Oil Servicing
During normal operation, the engine lubrication system provides either pressure or splash
oil to areas of the engine subject to frictional loading. A certain amount of oil
consumption is normal if the plane is flown on a regular basis. However, if excessive oil
consumption is noted (i.e. more than 1/2 quart (1/2 liter) per hour of operation) or there is
an abrupt change in the rate of oil consumption, determine the cause and correct it before
further flight.
WARNING
Do not fly the aircraft if oil consumption is abnormal or is
suspect; investigate for oil leakage. If no oil leakage is noted,
follow the “Cylinder Inspection” instructions in Chapter 7,
Maintenance Inspections.
