I guess beginning and end of season is fine for most folks. My fuel bill
last year was $420 so, roughly 120 gallons, 120 hours. Even someone who
motors as much as I do should be fine changing just spring and fall.

I would argue that if you change the oil at end of season, changing it
again in the spring is a total waste. The oil does not go bad over
the winter and any small amount of moisture picked up over the winter
months will evaporate after a short time running the engine. If you
really motor a lot, over 200 hours per season, changing it once in
mid-summer would be appropriate.

I tend to do Spring and Fall, if only to be more sure that the junk at
the bottom of the sump gets picked up. And it's possible that some
years I'll forget one or the other for some reason.

A couple of bucks' worth of oil is a minor outlay, even at our 20-30
hour annual use.
