The oil will gell at some point and apparantly that point can be found in
AK.

It's not the oil that freezes, but condensed water vapor can freeze in an
oil breather
tube, resulting in blown seals.

Then there is the Alaska way. Drain the oil and take it inside. Then
during breakfast, heat oil to 200 degrees. Pour hot oil back into
engine. Engine nice and warm. Chase off Grizzlies. Start airplane.

Your engine isn't warm, the oil is. You are much better off heating
the
oil while it is still in the plane.

The reason for the Alaskan habit is that when temps go low enough, a
chunk of frozen oil can develop in the crankcase. Even after
preheating the engine to what seems to be a suitable temp, you can
have a frozen chunk of oil surrounded by slightly warmer liquid oil.
I recall reading at least 1 accident report that was blamed on frozen
oil blocking the pickup. The engine had been preheated (but obviously
not enough).
