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,
perform a “Cylinder Inspection” in Chapter 7, Maintenance
Inspections in this manual.
Petroleum based aviation engine oil is flammable. Follow all
fire hazard precautions. Store the oil in a well-ventilated area
away from any heat or ignition source.
When adding oil, completely remove the protective seal on the
oil container to prevent the seal from falling into the oil fill
port. Prevent any debris from falling into the oil fill port.
If any oil is spilled on the engine and nacelle during filling,
clean up the oil spills on the engine and nacelle. Follow
precautions in wiping up oil spills.
