In the early morning, the density of gasoline is more dense, so should we refuel in the morning?

Is gasoline usually more dense in the morning?

According to HowStuffworks, it is true that gasoline has a denser density when it is cold , especially in the early morning when the ambient temperature is low. Therefore, there is a solid reason behind the theory that you will save extra costs if in the early morning. However, unfortunately, the reality does not happen that way.

The change in actual density of gasoline is very small and negligible.

First of all, assuming it's important when you buy gasoline, does this make any difference? Yes, gasoline is sold into gallons in the United States. (Even in other parts of the world, it is sold based on volume, although different measurements apply the same principle.) However, the density of gasoline changes based on its temperature. Cold liquid gasoline has a much higher density than when it has a high temperature. So there is a perception that a gallon of cold gasoline contains more energy than a gallon of hot gasoline.

These theories are not wrong, but the change in the actual density of gasoline is so small that you don't need to think about changing the schedule to refuel in the morning. Another thing is that most gas stations contain materials on the ground, in insulated containers. According to a Consumer Reports study, a small amount of gas on the ground in the pipeline can warm up if the time is long enough. If the gas circulated during the gas station's expensive day, this effect is almost negligible.

A Consumer Reports study also found that gasoline rising temperatures from 60 degrees to 75 degrees Fahrenheit (15-21 degrees Celsius) only increased by 1 percent. When gas prices are reasonably low, choosing the time to fill up only because of the increase or decrease in gasoline density can save you a few cents at a time. Therefore, you should not waste time thinking about when to refuel at the most economical time.
