Yes,
Great discussion!
There is often more then one right answer to a question. And we get to make our choices based on info given and our own thoughts and needs.
A couple years ago a friend gave me several things from a garage full of hoarded items. I was handed several cases of oil from way back in the time when made in round cans. Even a metal opener with spout.
I asked this list and did research and found the oil was as good as it was when new. As good as the standard of the day.
I gave it to several VW friends running air cooled and I think one vanagon. It was 20/50 grade.
It was happily put to it’s original purpose with no ill effects.
The oil was good because it had not been opened.
Call me silly but I usually change the oil depending on the miles when ever that is. But, If I have the option I do change it in the spring after storage. It just feels nice to start the season with known clean oil.
