Diesel truck in the winter out West.

What part of Colorado? There are only a few places you really have to be concerned about. We're seeing temps in the 70's in most of the state east of I-25 this week, so no big deal. That's not uncommon for Jan and Feb here. The coldest I've had at my house in the last 12 years is -17 and my 7.3L started right up with no help. It's not happy until it warms up, but it starts. Unless you're living in the San Luis Valley, Gunnison, or Craig area......I wouldn't even give it a second thought.

I did have a buddy that was working in TX and filled up his 6.7L down there and came back home with it. That fuel gelled up on him, but as long as you're getting local fuel here in the winter it shouldn't matter.......and you can run additives if needed. I always have a bottle of 911 in the truck for just in case.

Always easier on them if you can plug them in to warm the oil as mentioned above.

Just turned 386,000 on my 7.3 last week.

I had 319k on my 97. I loved that truck, it just started to really show it's age. My wife wouldn't ride anywhere in it cause she said it was "too old". Damn thing never broke down like her BMW suv. That thing was a piece of shit, but it was "pretty".
 
I got just under 200,000 on my '03 Dodge Cummins, original batteries and have never had a problem getting it started. We've even had a few nights this year where it sat outside all night long in -25°F temperatures, not plugged in, and started right up the next morning. It's not something that I recommend and it's always a good idea to plug in if it's going to be 20° or colder. Now, since I just said this, I probably jinxed myself and I won't be able to get it started tomorrow. As far as chains go, I have chains for mine and I'm also running 35x12.50's and I found them pretty easily up here but they weren't cheap.

That truck will be fine. We've been running Power Strokes on our ranch trucks since the inception of the Power Stroke and not all of them have block heaters. During very low cold snaps we will set a magnetic oil pan heater on the ones that dont have block heaters if they aren't going to be used for a few day just to make the starts a little easier. We see temps in the negatives for long periods all the time.

You can get any size tire chain you need from TireChains.com I ordered a set of 35" V-/Bar Heavy Duty for My Jeep this year that I am very pleased with.

Awesome. Just ordered them, I've never bought chains before $290 for a set of 4 doesn't seem bad for how heavy duty they are.
 
I just feed mine fuel, maybe change the oil around 10K miles, a fuel filter one a year, and drive it. I got 370,000 miles out of the the factory injectors.

Wow, you got your money's worth out of those injectors! I got about half that out of my factory injectors.

I got around 205k out of the 7.3 I had before I had to change them out. It just goes to show, cause I was religious about oil changes and fuel filter changes every 5k miles.

I think I only got about 160,000 or so, out of mine but it was probably more my fault than anything else. I used full synthetic oil but I only changed my oil and fuel filter every 15,000 miles. Since changing out the injectors I now have increased my oil/fuel filter changes to every 10,000 miles.

Mine knocked like a bastard with synthetic. Hot summer day and idle in front of the garage door or a drive up and it sounded like a rod was gonna come thru the side.

Delo all day everyday. You can't run synthetic in south Texas summer. You might as well pull the plug and idle it up to 1500 and hope for the best.
 
My work truck is a 2015 f350 powerstroke. I have never had a problem starting it and it spent a lot of time between -26 and -35 this winter. Never plugged it in.
 
2008 Duramax, zero issues. Definitely plug in below 0*, and keep up with any maintenance. I've swapped it 3 glow plugs in almost 100K and have my glow plug system tested at the start of winter. Never had any issues unless I failed to plug her in for a bit, recently at -17.

Always run a good winter fuel additive, I use Archoil. Clean and protect your battery posts to ensure a good connection.

What did you replace the factory injectors with? Did you change it up at all? Do you have any tunes on your truck?

replaced with factory injectors. I have a 6 speed so I use the old plug in supertuner. It's programmed for "hi performance" and has been since I bought the tuner many years ago.

I have the 6-speed as well. Haven't gotten motivated enough to put any tunes on it yet. But sure wouldn't mind a few more horsepower.
 
I have a 2003 f 250 and live in central oregon this winter it was 30 below for about a week and at that temp a block heater sure helps but Ive cold started it at those temps and been fine.
