Live in N Texas and haven't had a problem, until this past winter.
With our "freezeageddon" this year, and no personal knowledge of the best additive, looking for suggestions from the northern climate truck owners.
All the anti-gel sold out here locally during the freeze, and I don't believe that they put anti-gel in the fuel here (I could be wrong), so I want to pick up something now and be prepared.
Courage is the feeling you have right before you fully understand the situation
