Today’s tip will help you save a little bit each time you fill up, especially during the hot summer months.
Fill up early in the morning, when the day’s temperature is at its lowest.
I came across an interesting article that goes in depth regarding how “hot fuel” can end up costing you lots of money over time:
“As a liquid, gasoline expands and contracts depending on temperature. At the 60-degree standard, the 231-cubic-inch American gallon puts out a certain amount of energy. But that same amount of gas expands to more than 235 cubic inches at 90 degrees, even though consumers still only get 231 cubic inches at the pump.”
The 60-degree standard that is referenced in the above quote refers to the highest temperature at which gasoline should be sold, as stipulated by the U.S. government, and apparently is something that most people are unaware of.Â I know I had no idea about the standard until I read the referenced article.
Unfortunately, this is hard to enforce and most gas is sold atÂ a much higher temperature than 60 degrees – meaning you’re paying for gas that you’re not even getting.
So what does this mean for you, the consumer?
It means that in order for you to get the most gas for your money, you should try and fill up your car in the morning, when the air temperature is the coolest AND the gasoline temperature has had enough time to drop over night.
While the savings may not amount to much each time you fill up, over time you should start to see a difference.
