Fuel heaters and lots of kerosene mixed in.And did I say smoke
When I used to run up to Aroostook county Maine in the winter time I always doubled up on the fuel conditioner and most times I plugged the truck in at the hotel or left it running all day while I slept.Too damm azz cold even for me.When Loring Air Force base was open there was a :: load of freight coming into the county.I've seen -24, most trucks run a 50% mixture of
#1 and #2 fuel up there. cold azz place for sure.
