Morning engine warmup??

[Brock]

I'm bat shi#t crazy when it comes to warming up my engine's, if I ever seen one of my drivers start the truck and drive away within a minute.... he'd be driving home.

I don't care if it is 100 degrees out, I let my engine warm up a good 15 minutes while I get a coffee. I do it with my personal vehicles too, won't operate one until it's showing operating temp... forget about a big rig hauling stupid heavy weights lol

I've got to reasoning or scienece/data to back up why I do what I do.... just always done it and when people ask, I say "it's called operating temp for a reason"
