Oil change and filter every 5k miles or six months. What if one only
drive 4k - 5k per year. I know the old argument about moisture
forming in the engine and oil - or is is self preservation for the
auto industry. Why would that same moisture not be a problem in oil
storage vessels of whatever kind?

Condensation in the oil is a function of heat. The engine attains
relatively
high temps, and when it cools, condensation forms. The condensation does
not
form in storage containers.

Any condensation in the oil evaporates when the oil reaches operating
temps.


Well does it or does it not. One can't have it both ways. I (also)
think it does.



Whether ALL of the condensate evaporates depends on how much condensate
there is, ambient air temperature and humidity, how long the oil is at
operating temperature; oil properties; oil additive properties; fuel
properties; and engine operating patterns. The large number of variables
makes it difficult to make a blanket statement that the oil is good or not
without either testing the oil or installing oil change computers/monitors,
so the factory makes recommendations that cover most operating situations.

One won't go wrong following the factory recommended service intervals,
but if one thinks that one knows more than the folks who designed and built
the vehicle, then one is free to follow or ignore those maintenance
recommendations.

We are only talking about 25 bucks and a half hour of time for an oil
change on a vehicle that costs many thousands of dollars.

If you use the crappy oil its $25.

Castrol GTX is crapy?

Its not a full synthetic oil which means its crappy.
