Old oil become contaminated from the by products of combustion. Get it hot enough and it begins to form an acid that can cause corrosion. Ever disassemble an old engine and find orange staining? That from the acidic effects of old oil and sitting.
Changing the oil should reduce the amount of this acidic oil. Change the oil, run engine for a short time and the old oil should be flushed/diluted before storage.
With that said...I sometimes leave old oil in there.
Ive got $12k agreed upon value, full coverage on everything, no mileage restrictions, no receipts or appraisal needed and $207/year!!
True as that may be, there are brand new cars that sit on car lots the amount of time that a car might be in storage over winter. I don't think it's the end of the world to say the least. It may be worse if you have really old used oil in there before you put it away.
I agree. Plus after sitting all winter the oil is all in the pan. When you drain it you get all the old oil out, then refill with new. No reason to do oil change before storage. I don't put mine away for the winter. There are nice days in the winter with no salt on the roads.I hear a lot of guys talk about changing the oil before storage, but that to me is silly because the oil just sits in the pan not doing anything but aging, so I personally just leave the current oil in it and do an oil change first thing before the first start up in the spring.

Either way, it sure as hell doesn't hurt, especially if this is a summer-only type of car and the oil change is usually done in the spring time. By the time fall rolls around, more than likely an oil change is due depending on how much the car is driven.
Like I said, i've done both when doing short term storage so it's really not a critical point here to go back and forth over.
I have $23K value and 3500 miles a year for $470 thru American CollectorsFrom who? I just redid the hagerty quote. $10000 and 2000 miles is $507. $15000 and 2000 miles is $627

if the container is sealed its ok.
Yeaaaa for an engineer's attention to detail!
