It has a lot to do with what kind of building the car is stored in. So true, especially dependent an what part of the country you live in.. In Florida there is no "bedtime" as we here can use our toys all year round.... Personally I believe in the before I put the car to bed theory of getting the contaminated oil out and clean new oil circulated throughout the system.. Anymore, if the oil is clean I just put it to bed as is, even driving it another season with the same oil.. First good warm up and drive will burn out all of the condensation..

The acid in the oil etching the bearings while in storage theory is why I change my oil before storage now.
Plus it seems like every small engine manual says to do it before storage. I've heard this before a lot too. I don't have any data to back up my claims but I've pulled apart several engines that were sitting for years in old oil and I have never been able to find any sort of wear, damage or corrosion from sitting in used oil. I read a storage post from an oil expert and they suggested to chance oil when putting car in storage and not to start the car at all until removing from storage.They said just starting the car when doing the oil change alone would put acid in the oil and defeat the purpose. So according to your expert, what's the difference between storing an engine with used oil vs an engine with new oil in the pan but used oil still on all the bearing surfaces as it would be after an oil change if you didn't start the engine to cycle it through?

For me the stored car should sit with fresh oil vs used but the biggest killer for any engine is dry start ups. Changing the oil then not starting it until 5 months later is definitely not shortening the time for oil pressure to develop. Quick oil pressure right after fire up is the key to long engine life. That is why I prefill my filters and start the engine as soon as the new oil is poured in.

Yeah that oil pro statement makes ZERO sense. You have to start it to check for leaks or you are not done with your oil change. I think what he means is, do not start the car during storage.

The acid in the oil may be true in theory but the amount after running it for a few minutes after the oil change would be absolutely minor.
The only part is agree with is NOT starting it up while in storage. Idling will not get the oil hot enough to get rid of the moisture.
As for all the other ways to do the end of season change. I'm sure nobody will have any problems. Nobody is going to ruin their engine by doing some other method, we are just sharing the best way to do it.
