Hello,
I wonder if when doing an oil and filter change, draining the oil left on the motor belly unscrewing the underneath bolt would need to purge the system.
I would like to do that because in my plane is imposible to drain the oil tank from bottom removing the bolt, no access. I need every oil change to use a suction pump, and would like to get rid of the old oil as much as possible without opening the suction part of the system and need to purge.
Is that ok?
Thank you
