    Coming from Wisconsin, we never ran straight #1. Not sure about modern trucks, but years ago we used to "blend" our own, say, 30% #1, 70% #2. Fuel in northern states is blended from the refinery, and probably good for 20 below right out of the pump. Any colder than that, not sure what they do? I suppose Ice Road Truckers would know,,,:rolleyes:

    If it is really cold out like 10 below or lower I try to put like 20 gallons of number 1 in each tank and than top it off with the blended fuel or if its straight number two I might even put more number 1 in like 30 gallons in each tank. I look at the price difference and than I think if I have to hire a tow truck or a mechanic that .10 or .20 cents a gallon difference is pretty cheap. In the reefer I always try to fill with number 1 so you have a good blend if you end up having to buy some fuel down south or out west.

    Fuel is usually treated with antigel when it's dropped at our northern locations.

    Some places sell premium fuel that is winterized. In addition to what they sell as not winterized. But most places that sell a volume of fuel have dealt with pour point issues on all or most of the fuel they sell for trucks. The pumps freeze up if they don't.

    Cloud point of straight #2 is like 20F..... gel point is probably low teens or high single numbers above 0F. That’s a guess from memory..........

    and bio blends are worse......

    You can ..... if it’s cold enough I would. Otherwise it’s just a waste .

    you get less mpg and it’s harder on the top end also.....

    Just put some anti gel in is the easiest way. Every other fill up I put the small bottle in that treats 160gal and haven't had it gel up. Few times it's sat over a real cold weekend I pop the caps off and take a peek it was still fine not cloudy
