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.
