There seems to be regional differences with ULSD gelling. Some have had problems others have not. I suspect it goes back to the regonal fuel distributors as to what additive package they ordered from the refinery. If you are staying in a region you pretty much know what you are buying. But if you are traveling around the country your best bet is to buy from the same chain of truck stops as you travel.
