Ergo is you change oil before storage in winter, there is no reason to
change it again when it comes spring driving time. I think that issue was
at the heart of this thread, so I wasn’t picking your thread apart. I am
just trying to cut through the mysticism and find out if oil goes bad
sitting over a winter. On the two counts you and I have discussed, I’d say
it does not.

Say, this list still has some life in it! This discussion takes me back 20
years.
