I use FPPF Total Power and #1 any time 0F or lower ambient is in the forecast. I also use additive anytime I'm buying fuel from someplace that looks like maybe they don't go through very much diesel. Other than that, #2 from a reputable station, #1 and additive if it's going to be cold. The additive added to #1 to add back in some of the lubricity that #1 lacks.
New fuel filters every-other oil change (5K changes) as well.
