I hear trolls have a similar sound.
You really should let the truck warm up before you take off so you don't risk oil starvation due to excessively-thick oil. What weight oil do you have in your engine right now? You may want to try running Mobil 1 0w30 if these temps are common.
I would consider starting your truck and driving off at -4F/-20C without any warm-up to be abuse. Just don't do it.
Patient: It hurts when I bang my head against the wall. Do you have any advice?
Doctor: Don't bang you head against the wall.
Same applies here...first-poster.
