Ja, I worked one Winter as swamper on the fuel truck. 23 hour days or should I say nights. Most of the time the windows were down as we were dressed for the cold and the heat would put you to sleep. Sometimes we didn't get to the equipment in time and it had run out of fuel. -40 diesel fuel on bare fingers, bleeding the injectors adds new words to your vocabulary. It's -35Â°C out right now and I suspect it will get colder yet. Gotta let the coals burn down a bit before reloading the stove for the night.
