Sneaux next week [Historic snowstorm in southeast Louisiana on January 21, 2025]

... this is kind of the opposite of, say, a potential hurricane evacuation, no? In this current snow event, the emergency procedure is that you DON'T drive. Ergo, no need for additional gas.

EDIT: Or are you thinking of another angle altogether?
Something about the less gas then the more air I’m in the tank
More air = more condensation = more water = bad for engine

I finally have a very cold + car engine question and Terps is no where to be found
