Some good responses here (and I knew there would be!). I agree with everyone here; the day I start taking advice from Good Housekeeping is the day I turn in my man card. By virtue of where I work (maybe 5 minutes away) if I didn't let my truck warm up in the morning for 10 minutes or so before I left, it'd
never get any real run time. I firmly believe that it'd do (like John said) more damage to jump in and take off in subzero weather than let it warm up a bit. Fluids, tolerances, and more need a few minutes to warm up. But I guess people are going to do what people are going to do. My truck is over 110k miles and still runs like a champ so I plan on continuing to warm up before I pull out of the driveway.
