Hi Nuzza & everyone,
I have the exact problem, my 912ULS engine is somehow using oil. After 25 hours since last oil change, I have lost 200ml of oil. My engine is 350 hours young. I can't see any leaks nor oil burn stains on prop or tail plane.
Therefore I can't see evidence of it burning or leaking oil, and YES I do gurgle the oil tank as per publication instructions. I have never lost any oil until now, is it hiding somewhere?
Can someone please tell me what the hell is going on?
