When it is sub zero, you plug them in. That is why they make heaters.
It sure saves a lot of wear and tear no matter what brand of oil you use.

That is for those of you who live in the perfect world of having an outlet to plug into. We don't all live in that world.

I'd only use synthetic in a diesel if I lived in a place where you tend to see extreme cold. Barring that, synthetic doesn't offer any advantages. My 98 dodge/cummins has 340,000 miles on it and it's had nothing but Rotella T 15W-40 put in it every 7500 miles with a fleetguard stratopore filter and it still pulls like a train. Very few people keep their pickups that many miles. Regular old dino 15W-40 from one of the name brand makers will provide all the protection you need for far longer than most people keep a pickup.

What is the reason behind that...please explain?
Because once the syn cleans your oil system out why would you want to put heavy gunk back in it? Syn is always lighter weight than the standard 15-40. And, don't be fooled into changing oil every 5k miles. The only winner is the syn mfgr. Those oils are meant to be changed every 25k miles!

What, you live someplace that doesn't have electricity. I'm 15 miles off the paved road and five miles past that into the forest and I have a plug in!

Well, I read manuals. In the owners manual for the 2007 Cummins/Dodge truck, it specifically states that if the expected temp range is below 0*F, 5w40 synthetic oil should be used. I guess you could phone the Cummins engineers and tell them as to what your experience is and ask why they put that in the manual.  
I'd suggest placing a container of 15w40 outside overnight next time it's -35* and see in the morning what you're asking to circulate through all of the tiny clearances in your engine. It's pretty thick.  But hey, it's your truck that you paid for!
Me, I'm a bit of a stickler for things like oil and general maintenence.
My trucks don't have "tiny" clearances. Obviously you don't read my sig. They run on dino and they run hard. Winter here is late Oct to mid-Apr for below freezing weather. Our trucks run all the time, shutting down only long enough for fuel and maintenance. That's the way it's always been. If Cummins is so concerned, why don't they put all syn products in their trucks?

Yup,using a bike pedal generator as I type.
Seriously, there are many times I have had to park overnight where there are no outlets. They include truck stops, motels and apartment parkings lots.

Changing synthetic oil every 3-5k miles? Waste of money. Mine get changed every 15-20 with the oil fiter getting changed twice. As far as synthetic oil breaking down? Takes a long time to happen the viscosity breakdown will not happen does not get hot enough. Don't waste your money every 3-5k miles let it go awhile you're not hurting anything.

Run it to the recommended change interval, do an oil analysis and then make your decision. If it comes back that the oil is still good then increase the interval before the next change. Do this until the oil comes back with recommendations from the lab and then work from there. Easy and opinions (like this one) are not part of the picture.
I just did an OA with 6700+ miles on dino with 50% of the miles towing 10,000+ lbs from elevations of 200 ft to over 8500 ft and my dino tested that there were still miles left on it.

I just returned from overseas where dino oil sells for more than synthetics. Synthetics are in just about every vehicle sold as OEM. My friend's BMW has a recommended interval of 24,140km btwn oil changes. I just purchased a Toyota Pre-Runner and it came with synthetic oil.
