1. Special Characteristics of Petrol
Petrol is a volatile liquid that can evaporate easily and has the ability to expand and contract according to the temperature of the environment. Specifically, petrol expands at high temperatures and contracts at low temperatures. You can learn more about the use of petrol in motoGP to know more about the experiment of the changes in petrol with temperature.
According to the calculations of car experts, if the temperature difference is about 40 degrees Celsius, the volume of petrol will change by about 3.78 liters. So, if you fill up the fuel tank at noon or in the afternoon, the petrol in the tank will expand. It may even lead to fuel leakage, causing damage if your car is parked in a place with the risk of explosion.
2. Should you fill up the fuel tank or just add 50 thousand?
As mentioned above, the volume of petrol can change according to the temperature of the environment. If you fill up the fuel tank and have no travel needs. So, don’t say “excuse me, fill up the tank” okay. In addition, if you fill up the fuel tank, you will encounter issues such as:
Overflowing fuel tank: If the gas station you fill up at does not have pumps equipped with sensors to automatically shut off when the tank is full. Then the gas station staff will have to manually monitor. This can lead to fuel overflow when trying to fill the tank.
Difficulty with payment: The majority of gas stations nowadays conduct transactions in cash. And when filling up the tank, even if there is a sensor to determine that the fuel tank is full, sometimes you have to deal with paying with small denomination currency. This will make it difficult to give back the correct change. Or to solve this problem, the staff will try to fill up the tank to an even amount to make it easier to deal with the payment. The consequence can be fuel overflowing, causing waste.
3. Best time to fill up the fuel tank
The ideal time to fill up the fuel tank is in the early morning. After experiencing a cold night, the petrol will contract, so the amount of petrol you fill up will not be significantly reduced.
When filling up the fuel tank at noon, the ambient temperature is higher, the volume of petrol will increase, which will significantly reduce the actual amount of petrol you receive.
You should fill up the fuel tank at gas stations where there are many taxi drivers or truck drivers. This is a small tip to help you choose a reputable gas station.
Because taxi drivers and truck drivers frequently travel, they will have the most experience in fuel-related matters and know which gas stations are trustworthy, ensuring quality and never being cheated.
Based on the number of liters and the distance traveled in each purchase, choose the gas station that you feel most confident in.
