Hope you're in front of the fire Silver. Last time I saw -52C around here I was working on a service rig, 18 yrs old, and the rig push told us to start the rig. Our driller argued that it was too cold to work, but he insisted - from the comfort of his truck seat - so we tried starting it, and both the oil filters on that ol' Detroit cracked. When we finally got them off and pulled them apart, the oil wouldn't even flow out of them. It was frozen stiff. We tarped it in with a Herman-Nelson heater and let it sit for 2 days before trying again.
