There are two times of the day when refueling allows you to save something: this is when you should refuel.
The increase of the fuel price found in recent months forces us to find various tricks to try to avoid that every refueling we do becomes a bloodbath for our wallet.
There are those who are lucky enough to live near the border with countries, such as Slovenia, where the price of a full tank can be up to 50 cents per liter lower than in our country. Who improvises himself as a taxi driver, studying the best way to save with a car that is not too fast and constant.
Inflate the tires, use additional systems sparingly, carry out regular car maintenance. Of conventional methods in order not to waste too much petrol or diesel there are many: there is one that concerns the actual refueling and, no, it does not require us to emigrate to another country.
In fact, there are two moments of the day in which refueling can be decidedly cheaper: and, according to a theory, not only the discounts applied by some distributors in certain time slots have to do with it, but a simple and effective one comes to our aid. physical principle.
Does fueling early in the morning or at night really save money?
Yes, we have spoiled the moments of the day with the title of the paragraph: if you have the foresight to go to your trusted distributor at times like early morning or night you can have a potential advantage.
First of all, there is a economic discourse. As we have said, some petrol stations apply some affordable rates for DIY if carried out in times of low crowding, such as early in the morning or at night.
And then, surprisingly, a physical law is also part of the reasoning of convenience. Let’s try to be as clear as possible, following what this says new theory.
By making petrol or diesel in broad daylight, the heat will cause the fuel to expand by thermal expansion, making it less dense and therefore, according to a physical principle, with a lower energy yield.
Conversely, at night and early in the morning, when temperatures are lower, they would favor the density of the fuelwhich consequently translates into the possibility of covering more kilometers by spending the same amount.
IS a theory that spread rapidly on the net: according to some calculations that have been estimated, this method would save about 3 percent of the total supply. Not bad, but is it really so?
Now comes the bad news and it is logic that gives it to us. A Consumer Reports report, which inevitably ended up investigating this method, it reminds us that fuel is stored in insulated and underground tanks where the temperature is not influenced by what happens outside.
So, whether you go in the winter night or in the summer noon, in fact nothing will really change. Or rather, nothing particularly relevant. Unless the distributor applies some night ratesbut in that case physics would have very little to do with it.
