Burping 912

I don't think it makes much difference, really...  If you do it post flight, you'll still want to look in the tank pre flight and make sure enough oil is still there  :)

I'm with Tyler. Either before or after. They both work. Perrsonally I prefer before so I feel confident the oil is there before I take off.

 Agreed.
I always consider the oil check as a 'Preflight' item.
Surely if OK on post flight, unless there is an oil deposit on the deck or in the cowling prior to next flight, should be good to go!

Cheers for your comments.?
