I’m running 15w-40 with no issues but it doesn’t get much colder than freezing here and not for more than a day or two.

Good to see another Canadian member. I am only about 4 hours away from you.

I run Motorcraft SAE 5W-40 Full Synthetic Diesel Motor Oil year round in Alaska and am very happy. My alternate choice would be Amsoil SAE 5W-40 Signature Series Max-Duty Synthetic Diesel Oil. If operating with temps below -20 Degrees F (-29 C) I would use Amsoil SAE 0W-40 Signature Series Max-Duty Synthetic Diesel Oil. Good luck, Russ

I use Chevron oil, but not because it's better than other brands, I get a good deal on it, and the bulk truck pulls right up to the shop, and pumps it off into my tanks. The same truck also brings me bulk DEF, cases of washer fluid, and drums of gear oil and antifreeze. If I got as great of service somewhere else, I might switch brands. The same oil goes into all the semi trucks, and heavy equipment, not just light duty diesel engines like pickups.
