Guess we see things a bit different. But from my thinking allowing the upper engine to drain that long has gotta be bad when you start the engine. Oil takes time to fully pump up to fill all the oil system as opposed to short oil change time. The difference is the oil pump is completely drained of oil after a week.How is it any worse than just letting the vehicle sit for a week ?
I'm surprised some don't pour a sacrificial quart of fresh oil to push out that 3oz of residual bad oil.
What about parking at the airport for a week? Or leaving one car at home for 2 week vacation? Even if you drain for a week, it won't be any different than just parking your car where most all the oil falls down into the pan.Guess we see things a bit different.

Are you forgetting where you are ? Four pages of stressing ..Its nothing to stress over.
I understand what you are saying. Here is my view… The oil filter usually has a check valve that allows a lot of resistance to complete drainage along with the gear oil pump. Bet there is no issue at parking at the airport. However draining the oil for a week with the purpose of complete oil removal means the pump is air bound and all oil passages are drained. Personally would not do it, but open to your thoughts.What about parking at the airport for a week? Or leaving one car at home for 2 week vacation?

Its nothing to stress over. A vehicle that has been stored for years will still have an oil film all over the internals.
To prove it’s a waste of time. 3 oz for a week of waiting? goes to show, after a handful of minutes, nothing of value is left to come out.Why?
Just think how much you could have gotten in a month!
