Here in NH we have seasonal fuel. I also run Power Service additive during extreme cold spells. I start plugging in when it gets down near zero, dont know if it needs it, but it does warm up quicker. My Ram came with a vinyl 'cold front' grill cover, but I never noticed much difference when I've used it. It does keep snow and ice out of the grill and air intake however! Modern diesels have few of the issues that plagued the older versions.....
