Is it more efficient to fuel your car at night?

    According to CBS, this is actually an urban myth. The rational behind this “money-saving tip” is that gas is colder and more dense at night, meaning that you will be getting more gas for your money. The authors of the article below conducted an experiment, and found that is extremely hard to predict whether the gas at the pump will come out hot or cold. The fuel tends to stay the temperature it was when initially put into the storage tanks for awhile, so if it was delivered warm it has the potential to stay warm. And even if you do manage to get cold gas, the savings seem to be minuscule; it is believed that the density will increase by one percent at most, not significantly increasing your fuel intake or giving you much more bang for your buck.
