Need to warm up truck or not?!?

Ok, I have surely heard a lot of folks who insist that we must warm up these trucks before rolling them down the road. I have owned a few diesels and many gassers, never had a problem with this technique. Back in Buffalo, I warmed up the car because I wanted to be warm not because the car needed it.
I have always been of the mindset of oil pressure = good to go. I let it idle for 30 seconds or so and I am off, no matter the temp. I don't rip on it, I just drive a touch slow the first .5 miles then normal driving.
I wish there was a retrofit kit or something for instant cabin heat like the new Powerstrokes have.

What are your thoughts?

Scott

I don't warm up, just do like you and let it idle for about 30 second and take it easy until it's all the way up to temp. If I get a PHP I will get a high idle position, but I wouldn't let it just warm up at standard idle for very long.

Agreed.. I think 5 mins max(in extreme colds) would be the longest, even then its not building heat in that temp, unless you have a high idle tune..

I plug mine in on a timer below 30 that comes on 3 hours before I leave. Then I start it, scrape the windows and leave. It gets driven like I'm 97 years old until the temp comes up a little bit though. Don't really know if this is really necessary I just don't like the sounds of ball bearings getting launched around under the hood till she's warmed up.

I do about the same, it might get a few extra seconds if I need to scrap the windows but idling away for 20 minutes isn't doing your engine any favors. If you want heat in the cab quicker I would plug the truck into the timer and have the timer set to turn on 3 hours before you leave.

I have it plugged in under 35, as stated above also with a timer and 3 hours before start. I start it, hit the high idle, go inside and grab the existing things I may need, and fill up my coffee cup and water bottle, then leave. I keep the RPM's under 2250 until my temp gauge is in the nominal range. I am unsure if the temp gauge is an idiot light like the tranny gauge though, when I do a fuel pressure gauge I am getting a true engine coolant temp.

Heres what I do.

I go out start the truck. Run back in quick grab a soda and give the dog a treat. Then I go.

Once it gets down below 15 degrees I plug the truck in on a timer set to come on 3 hours before I leave. The rest of the routine is the same

I'd at least give it long enough for the glow plugs to turn off, which is about 90 seconds. It really depends on how cold it is and if it's been plugged in. If it hasn't been plugged in, I'll let it idle for a few mins for the smoke to clear up.

In the summer I don't warm mine up very long, maybe a few mins and i'm off. But in the winter I plug in and let her idle a good 15 mins or so before I even hop in it(remote start). But I live in AK so it gets a little cold and I hate cold trucks. Heated garages FTW!

Similar to Dave. I fire her up. Got to the mail box and get my AM paper. Set the radio and go. So its about 2 minutes.

If it is really cold she is plugged in. This morning it was 30* not plugged in. By the 2 minute mark she was at 65*. I limped down the road for the first few miles.
