Is it true that filling up gas at night is better or will you get more fuel than during the day? Or is it actually the same whether you fill up gas during the day or at night? Many people are still unaware of the facts about this, so we will provide more accurate information for you.

The myth that is still circulating and believed by the public today is that filling up gas at night is considered better. This is because when filling up gas during the day, the gas will evaporate due to the heat from the sun. Now, to know the facts, let's look at the following explanation.

Here Are The Facts About Filling Gas During The Day Or Night

The various characteristics of individuals when filling up gas create their own habits. For example, some prefer to fill up gas at night because it is considered better than during the day. Additionally, many believe that filling up gas at night will result in more fuel.

In response to this, Reza Sukarja, Head of Affiliation at the Oil and Gas Institute (Lemigas), Kebayoran Lama stated that the belief held by the public is a myth. 

“It is clear that this is a myth, because whether you fill up gas during the day or at night, the volume in the tank remains the same,” he stated. 

Furthermore, Reza emphasized that the placement of fuel tanks at gas stations has been specially designed to not be affected by outside air temperature or sunlight.

This is because the material used for the fuel storage tank is made of polycarbonate and special metals. Thus, these materials will not be easily affected by changes in outside temperature. They also ensure that the flow of fuel from the storage tank to the car tank maintains the same and stable temperature. 

Should You Fill Gas During The Day Or Night

Often, many people believe in the myth of filling gas during the day or night. However, it is important to remember that you should think rationally and according to the facts. 

This myth is indeed widely believed to be true, but filling gas either during the day or at night is essentially the same. The most important thing when filling gas is to do it when the fuel is running low so that the vehicle can continue to be used.

In response to this myth, Eko Kristiawan, Unit Manager of Communication Relations and CSR at Pertamina MOR III, provided a brief explanation. According to him, gas evaporation can occur but not in significant amounts.

Therefore, the volume of gas when filling up during the day or night is relatively the same. There is no significant difference; the content remains equally beneficial according to the amount you purchase.

“The assumption regarding evaporation is not significant. So you can fill up fuel when it is running low and it is time to refuel, of course, to avoid any issues during your activities,” said Eko.

Eko also added that good fuel filling is not determined by the time of day, whether day or night. Instead, it is determined by the quality of the fuel, such as the Research Octane Number (RON).

A higher RON value usually indicates better fuel quality. Quality and environmentally friendly fuels include Pertamax, Pertamax Turbo, and Pertamina Dex.
