I always fill up in the morning because that is the most convenient for me. Either I'm off from work or going to it, it's cooler so I don't bake when I'm pumping the gas/checking tires plus no waiting and less peripheral traffic to worry about. The temp variation thing was (I thought) geared towards above ground tanks like some in Canada. I'm not sure how it matriculated to the states but whatever. Didn't break my routine.
