Gas line anti-freeze I usually go to the paint department and purchase a big bottle of methanol (aka methyl hydrate, methyl alchohol or wood alcohol). I add a bit to each gas tank filling.
Much cheaper than those tiny gas line anti-freeze bottles sold at the gas station.
Today the 10% ethanol mix at the gas station was the same price as the ordinary gas. I filled up with that.
Any water condensation in my tank will just dissolve into the gas/alcohol mix and be drawn though the engine, no problem. The water won't pool at the bottom of the gas tank and freeze up and plug the gas line.
You have to be very careful running any mix of ethanol in today's cars. Granted certain states are required to sell it, but not many cars are capable of running it, as it still affect Oxygen sensor performance and can cause running problems. Most manufacturers have engines that are capable of running it now, but these are designated as FFV (flex fuel vehicles) where the onboard engine computers can compensate for the burning difference of the ethanol. Older vehicles prior to 1996-1997 are not recommended to run an ethanol mix. For those vehicles we used to get a couple of bottles of 90% isopropyl alcohol from the drugstore to put in the tank.

I love living in Minnesota. Did you catch how BradMc said that it gets a lil chilly (-40) That's what my wife says too. Its a little chilly outside and its 30 below zero. We say that it is warming up when it hits 5 above. Its downright pleasant at 36
