Each engine/airframe combination on every piston engine aircraft I have ever encountered has a certain oil level happiness somewhere under the total capacity of the engine.

No matter what the op manual says, that's all your engine wants and if that is not BELOW minimum operational capacity-it's OK. EVERY engine has it's peculiar aspects.

I filled to 9 qts the other day, flew crosscountry for 315 miles or 1.8 hours and there was a quart of oil on the rudder and belly.

I operate a an AEIO320, with the Christen inverted system, and do some aerobatics. I loose just about 0 oil from the breather. The belly is clean. Could you have a problem with the check valve in the Christen breather tank?
