I had a car back in the 70s that I had to add 2-3 qts of oil between gas fillups. Fun times.
You are spot on with the oil aeration issue. I drilled it into my 4 kids to not overfill their oil for that same reason.
Your engine can consume a great deal of oil without so much as a puff of smoke out of the exhaust, and you wouldn't even know it. A defective PCV valve can do that in a heartbeat. It takes all of 2 minutes to check my oil at the gas station. An ounce of prevention. I'm not taking any chances.
