January in Eastern PA is not typically warm but this year has been rather different. The mild days allowed for a lot of electric driving and no FORM. I’ve really made it a point to allow the engine to fully warm up if it starts. The grille plates that are installed seem to allow the engine to warm up quicker and stay warm.
