On an everyday basis, I let my truck warm up or idle in the mornings for about 10 minutes with exhaust brake on. I did it on both my 08's, my 2010 and now my '14. Since all others were deleted and the '14 isn't, I was kind of worried. But if you use the truck like a truck should be used I don't think a little idle time is gonna hurt. I would rather leave it idling a bit longer in the morning, rather than being in a situation where I had to jump on the throttle with a stone cold motor......... Bad for head gasket!!!

I start to move right away, 2ed, just letting the engine idle. No load on the engine. My first turn is a good downhill where I just let the engine slowly bring the truck up to speed, no load. A nice easy to start to get all the oils moving with no load on the running gear. Mornings get down to the low 20's.

In warmer temps of +40F and up ... Idle about 30 seconds to a minute and head out easy.
In mid-range temps of +20F to +40F ... Idle about a minute, engage exhaust brake and high idle, idle 1-2 minutes and head out easy.
In lower temps of 0F to +20F ... Idle about a minute, engage exhaust brake and high idle, idle 3-4 minutes and head out easy.
In colder temps of -40F to 0F ... Idle about 2 minutes, engage exhaust brake and high idle, idle 5-6 minutes and head out easy.
I use Deisel Service year around (one ounce per 3 gallons). Silver bottle in spring/summer/fall and White in the winter.
Our driveway is 1200' long and we always putz up the driveway and then go easy (regardless of temps) for the first few miles until getting out to the main roads.

Pretty close to seery here. When it starts staying around 20 or below each night I will usually plug it in on the timer for 2 hours before I leave. Then let it idle a minute or two, and take it easy. Not a leak anywhere, no smoke and no bad noises, it must work.
I fire mine up every morning and watch the oil pressure build up to 50 psi and stabilize. Then I throw it in reverse, back out then down the road I go. I drive very sensible until I see the coolant temp reach 185-190 degrees then I get on it a little bit after that point on the 4 mile stretch before I turn onto base. I also put my truck in tow-haul as soon as I fire it up just for the more positive shifts. Speed limit on base is 30mph and I don't like it searching between 3rd and 4th gear when not in tow haul mode also.
I may be a little to obsessed with how I treat my truck, I don't even like to park the truck with any load against the tranny. I stop and put the truck in neutral and let it settle into spot then set the parking brake then put it in park. I don't like that feeling on an automatic when you put it in reverse and have the harsh engagement into gear.

Engaging the EB actually helps the engine warm up a little quicker. Don't ask me how, but it does. Somebody with a more intricate understanding of the turbo would be able to tell you how it helps. To me it doesn't matter whether you use automatic or full, they both seem to work.
Now watch, someone is going to take that seriously and sit in their truck with a stopwatch! :hehe:

The EB will close off and put a load on your engine to bring up EGTs I've seen over 700 degrees on my pyro just high idling at 1100rpm... Sounds like a jet engine... But I'm deleted I'm sure you'll hear a little whistle in stock form.

Copied & pasted from my 2012 owners manual.
Starting Procedure – Engine Manifold Air
Temperature 0°F To 66°F (–18°C to 19°C)
NOTE: The temperature displayed in the Electronic
Vehicle Information Center (EVIC) does not necessarily
reflect the engine manifold air temperature. Refer to
“Electronic Vehicle Information Center (EVIC)” in “Understanding
Your Instrument Panel” for further information.
When engine temperatures fall below 66°F (19°C)
the “Wait To Start Light” will remain on indicating the
intake manifold heater system is active.
Follow the steps in the “Normal Starting” procedure
except:
1. The “Wait To Start Light” will remain on for a period
of time (length of time depends on engine temperature).
2. After the “Wait To Start Light” goes off, turn the
ignition switch to the START position. Do not press the
accelerator during starting.
3. After engine start-up, check to see that there is oil
pressure.
4. Allow the engine to idle about three minutes until the
manifold heaters have completed the post-heat cycle.
5. Release the parking brake and drive.
NOTE:
• Engine idle speed will automatically increase to 1,000
RPM and engage the Variable Geometry Turbocharger
at low coolant temperatures to improve engine warmup.
• If the engine stalls, or if the ignition switch is left ON
for more than two minutes after the “Wait To Start
Light” goes out, reset the grid heaters by turning the
ignition switch to the OFF position for at least five
seconds and then back ON. Repeat steps 1 through 5 of
“Starting Procedure – Engine Manifold Air Temperature
Below 66°F (19°C).”
Starting Procedure – Engine Manifold Air
Temperature Below 0°F (-18°C)
In extremely cold weather below 0°F (-18°C) it may be
beneficial to cycle the manifold heaters twice before
attempting to start the engine. This can be accomplished
by turning the ignition OFF for at least five seconds and
then back ON after the “Wait To Start Light” has turned
off, but before the engine is started. However, excessive
cycling of the manifold heaters will result in damage to
the heater elements or reduced battery voltage.
The procedure may be different for a 2013 & up truck, but thought this might be helpful. When I start on a cold morning, I let it run 2-3 minutes before putting in gear. IIRC, the one big thing to observe is, go easy on the go pedal until you reach normal operating temps.

Does anyone know if the dealer can stet up the EB so its on all the time? Or automatically comes on when the truck is started but could manually be turned off?

Here you go. I may be a 2014 thing only. See post 3&4. I doubt if the dealer will help on that.

In colder weather I wait until my coolant temp is at least 100*F if my truck was not plugged in. I let the truck go to high idle on it's own. If it was plugged in I'll let her idle for a couple minutes. In warmer weather I'll let her idle 30 sec to 1 min.
