What you don't want to do is have lots of summer diesel in your tank(s) as you travel towards colder climates in winter.

I always added a anti-gel additive on the last fill before winter. The rig started so quickly that it took too long to get oil pressure because the oil was so cold - even with the block heater.

So going into winter was the only time I used additives in the fuel.
