2. Slowly turn the propeller counter-clockwise (behind prop facing forward, if standing behind the
aircraft, several times by hand to pump all the oil from engine to the oil tank.
3. This process is completed when air flows back to the oil tank. This air flow can be perceived as
a murmur (gurgling) when the oil tank cover of the oil tank is removed.
4. Pull out the oil dipstick.
5. The oil level in the oil tank should be between the two marks (max/min) on the oil dipstick, but
must never fall below the min mark.
6. Replenish oil as required.
For longer flights replenish oil to the max mark to provide more oil reserve. During standard engine
operation, the oil level should be mid-way between the max and min marks. At higher oil level (over
servicing), oil will escape via the venting passage.
The difference between the max and the min marks is approximately 0.5 quarts (0.47 l).
WARNING: Oil changes are necessary more frequently when using AVGAS vs
MOGAS. See Related Information.
7. Check oil-level marks on the oil dipstick.
8. Fit the oil dipstick and tighten the oil tank cover by hand.
VERIFICATION METHOD:
Use the oil tank dipstick to verify the desired oil level.
