In normal operation, oil is drawn from the sump by the oil pump, passed through an oil
filter and thermostatically controlled oil cooler to the engine lubrication points and propeller
governor. The oil then returns to the sump by gravity.

As per Figure 1-4, the total system capacity is 12 US quarts (11.4 litres) and minimum
operating level is 9 US quarts (8.5 litres). For normal operations, maintain the oil level between
10 and 11 quarts, and top up if the level drops below 10 quarts.
CAUTION
Failure to ensure the dipstick locking clip is engaged may result in
the dipstick coming loose with a significant loss of engine oil through
the open tube end.
Prior to adding oil, check the Journey Log to confirm the correct type
and grade of oil is being added.
If checking oil within 1 hour of engine operation, the oil level may
appear low as oil has not fully drained into the sump. Do not overfill
with oil as serious engine damage can result.
