There is a school of thought that you should fuel up in the morning
because you will get more gas by volume than you will in the afternoon.
I'm sceptical about that one because the gas in the underground tank
probably has a much smaller temperature range than an exposed tank.

I've read that a 15°F temperature change in gasoline will cause a 1% change
in volume.
