Driving home today I passed a billboard for some gasoline company - I don’t remember which and it’s not really relevant. It wasn’t a sign saying “We’re at exit #X” or “Buy this non-gas item at our attached convenience store.” Just a general “This chain of gas stations exist in the world” sort of sign - like someone wouldn’t know that or suddenly think “Hey, I should find one of their stations and try their gasoline!”
So what I’m wondering is is do you have a preferred gas station brand? Or do you just fill up at the station that is most convenient and/or cheapest? Is there really any appreciable difference in the gas you might get from one place or another?
