My Piper Archer ii is spitting out oil above 5.5 quarts. My partner suggested we look into getting an air oil separator. I had no idea what this was 24 hours ago. After reading about them they seem to be very finicky. It needs to be placed in the right place and must operate over 212 degrees, even then it is likely to put oil mist into the air going to the cylinders. Am I reading the wrong things? The engine runs great even at 5.5 quarts. I personally think its just the engine's sweet spot. Oil temps seem to stay down and I don't think fidgeting with a well working engine is a great idea. Does anyone here have any experience with the air oil seperators? Is this a must install thing or is running the plane at 5.5 quarts and watching the temps a better strategy?
