In northern Maine, I was told that when temperatures got really cold, pilots would, after shut down, immediately drain the oil and take it inside to be kept warm on a wood stove and ready for the next start.
I used to use a "Red Dragon" engine pre-heater and learned early to never allow the 3# propane tank to get too cold because the propane wouldn't sustain enough pressure to fire the pre-heater.
At temperatures below 0° F, engine starting got to be a real challenge. Taking the battery inside to keep it at room temperature really helped getting enough juice to the starter for the next cold start.
