I wouldn't use 15W40 below 20 degrees. At that point switch to Rotella T5 10W30 or T6 5W40.

It's a tad on the cool side but i'm willing to sacrifice nominal mpg gains for better performance.

+1 on those temps

You want the coolant to be 190-215 degrees and oil will run 10-30 above that.

There's room for improvement there both in engine wear and MPG with lower temps when your haulin .. It's that simple

Thank you sir.

Looks like a different winter and summer weight will be in order.

Yep especially where you live .. Those villages that are running remote generators and equipment up there where you live probably have a good idea what oil weight to run in Winter and Summer also ..

Where I live, it is more temperate that the blistering cold that hits the interior or the northern part. I could possibly get away with running 10w30 or 5w40 all year long. Our summers don't get quite as hot as you all's.

Plus, with my work schedule (I work at a remote site), the truck will not see a huge number of miles per year.

One, maybe two. Not real sure yet as I have not really driven this truck. It's been under the knife for three years.

It should be on the road sometime this summer. (atleast drivable...

We won't get 0W40 in Colorado until next year.

Otherwise for year round use with little to no towing I would use Rotella 10W30. Or dump it in Spring for 15W40 for the warmer months with towing and then switch back.
