Little oil in filter during change

Post by Ace » Sun Sep 25, 2016 9:27 pm

I changed my filter for the first time on my AEIO-540 on my Extra at 50 hours. No oil leaked out as I unscrewed it, and there was little oil in the filter itself. Maybe a shot glass amount of oil. I had drained the oil over 48 hours prior to removing the filter, and the filter sits in the horizontal position at level flight.

Should I be concerned? I've never seen this before - usually oil gushes out when remove a filter and it's usually full of oil.
