lets blow away the mystery here. yes corrosion can start in a few
hours ....but why????
Because moisture is always present. No mystery...not sure why you say there
is.
Corrosion is a constant process, and the longer you go, the worse it is.
bull**** (and I mean that in the nicest way :-) )
Doesn't matter how nice you mean it...you're still wrong.
ok why??? what is the actual process going on here that makes the
running better?
Mostly it's the recurrent coating of corrosion-susceptible surfaces with
oil, protecting them from moisture. Again, no great mystery.
[...] I'm not aware of any unbiased
tests that would indicate one way or the other.
of course there are. you just havent read of them. :-) :-)
I'm all ears. Show me an unbiased report that compares efficacy of the
corrosion-preventative oils. I would love to be proved wrong, as such a
report would be very useful to aircraft owners.
moisture in the engine is primarily the bad guy here.
it condenses in the oil as the engine cools after use
It is also present in the air, and the engine not being a sealed
environment, humidity will get into the engine as it sits, regardless of how
much moisture got into the oil as a result of operating the engine.
[...]
the second time I took precautions to minimise water in the oil and
had no identifiable damage.
How did you attempt to identify the damage? Did you disassemble the engine
and inspect it for corrosion? Where was the airplane stored? Was it in a
desert (extremely low humidity) or in a coastal environment (high humidity)?
Regardless of the answers to the above questions, two years in service is
not enough time for you to notice the effects of corrosion. If you think
that corrosion did not occur in your engine during the second year it sat
unattended and unoperated, you are fooling yourself. The degree of
corrosion is highly variable, but to say that corrosion did not occur is
just stupid.
