Around here (MN) we don't usually get that much engine corrosion damage
but I have seen what I now recognize as cold start damage as being more
common.

Bingo. Those who say it's bad to leave your pre-heater plugged in often
ignore the fact that the alternative is to fly without pre-heat.

Question: Can a dipstick heater be used safely on an aircraft engine? Does
it help much? See eBay item 8006970279.
