I’m enjoying high-60s temps in December, it makes it more comfortable to install my engine heater. That being said, I almost always pre-heat the truck of the temps drop to the 30s - I like immediate defrost and heat. I also tell myself that it’s an investment in the longevity of the engine.
Seeing that Diesels don't really get that hot to begin with, is this something that can run alongside the engine while driving? or is a radiator muff a better solution once you're going.
