In another thread (about cold starting) it was mentioned that Alaskan bush
pilots routinely drain their oil, take it inside, and heat it on the stove
before starting in the morning.

While this guarantees a warm(er) engine, wouldn't this risk damage to the
engine from shock heating (assuming there is such a thing), by suddenly
introducing boiling hot (or nearly so) oil to a cold-soaked engine?
