Apologies if this has been asked, I tried looking for it. I did a pre-buy for a beautiful RV-9A and most things seemed good. There has been concern about the oil consumption. It seems that it goes through a quart every 7-10 hours. Is this normal? I've talked to some people who were thrown off by it being so low. Obviously the seller / broker seem to think it's good. The engine has 740 hours on it with a new cylinder 4 years ago. This is an IO-320. This is the plane.
