I'm new here and as the title states am wondering what the best additive for winter weather is Temps get down to -20°F so far the Ford dealership tells me to run Ford brand I can't believe that's the best stuff out there any suggestions greatly appreciated thanks. Dave
Almost all the fuel you get during the winter has been treated with anti gel however I still add PowerService fuel additive to my truck. A very common product found at farm stores, parts stores, even walmart.
