Q

What are the minimum engine oil quantity requirements?

A

60% (regardless if mx station or not) OR
70% for flights departing mx station
The PIC must arrange for engine oil servicing when terminating at a non-mx base when the oil quantity is <65% (note: with oil quantities of less than 65%, low quantity alerts may be experienced during initial takeoff and climb)
