582 crackshaft oil getting lesser..... help plz

[Kalahari pilot]

Good day

My 582's crankshaft oil is slightly lesser than 10h back.

It seems to have used about 1 mm on the bottle.
Motor has been decoted about 14h ago.
Is this a trouble maker in the air?? And what can be the problem?

Thanks for your feedback.

So in the meanwhile..... I've learned from my AP that it is normal for the 582 to use some crankcase oil..

I just did not like the fact that it use 10ml over 14h of flight.

Can anyone else confirm that its the norm?? Plz.
