The OP asked about...."with these things that blow dry
air ".....

I live in the Mojave desert, where the air is very dry also, so a dryer
is usually not needed. But for those that live in a wet climate during
winter they might be a worthwhile thing. I have no opinion or
experience with them, I just thought that since the OP is interested, I
would point him towards an information source he might find helpful. As
for being afraid of drying out the oil film on the engine internals, I
don't know. Seems that for rust to form you need moisture. No moisture,
no rust, I would think.

the "humidity" level around here averages 0-5%.

how can it get any dryer.. I'd be afraid of drying out the oil film that
rests on the exposed metal

are we trying to keep an engine warm for the next engine start?

or preserving the engine by removing unwanted moisture

Aviation Consumer did an evaluation in the current issue. They liked
them, and recommended them, although they didn't test the brand that
you posted. They said if it pumped dry air as well as the others, it
should work fine. Also, they said the 100 watt bulb in the cowl flap
trick works too.

I'm worried since I've only been able to fly every 2-3 weeks recently.
