Your point is valid, but my opinion is
that this corrosion is totally dependent on a combination of factors.
Namely, how often you run your engine, where you live, and what temperature you
get your oil to during your trips.
I hold that if you routinely run your
engine (every couple weeks) and get your oil temp to over 200 degrees for a few
minutes during your run, then you won’t have any water in your oil to
corrode. This is also drastically affected by where your plane is stored.
I’d love to hear more discussion on
this topic.

heaters distill water-the byproduct of combustion-into the unheated areas of
the engine. The water beads there and corrodes. And corrodes, and
corrodes.
