Unless you are talking a heated tank, the actual tank temperature doesn't change regardless of the amount of wind on it. Ex. If it is 10 outside with a 50 MPH wind, the tank is still 10 degrees.
Buying fuel in IN or IL is a bad idea in these extremes because they cut the fuel with a higher amount of bio which of course gels faster. If fueling there, you must increase the additive to compensate.
Case in point. I have a friend that has a Peterbilt dealership in WI that invested close to a million in road trucks. Why? Because he is waiting for people to buy fuel at say the TA in Hampshire and come up there and freeze up. He got his investment back several years ago.
In the extremes, Howes and Power Service are barely enough if it is below minus ten. Usually best to use those and cut it with 911.
If you call a service truck, guess what they are using? 911 mixed with one of the others.
There is my tip of the day.
