But it's kind of a non-issue at that point because it's so damned cold out that you just go and turn ur car on and go back inside for 15min to let the damn thing warm up inside haha.

Cold, thick oil that doesn't flow well and doesn't lubricate well + cold rings that aren't sealing well = gas pouring down you cylinder walls, contaminating your oil and removing any oil that did make it onto the cylinder walls.
What you end up with is bad scoring of the cylinder walls, oil that needs to be changed at about one fifth the normal interval and hours of un-documented (by the odometer) engine run time.
The answer, use a synthetic oil with that is very stable at varying temperatures, I'd recommend Mobile 1 or Amsoil 0W40, and a block heater. And even in the dead of winter, get in, start the car and drive, slowly.
