A citizen of Changchun said that the price difference between filling a liter of gas at a gas station is 100 ml, and most gas stations are prone to short of weight and short of weight in their lives. In fact, many car owners already know this, especially when many people are refueling, they clearly realize that their cars only have 50 liters of oil, but they can add 60 or 70 liters when refueling. Many car owners will also feel very puzzled. Obviously, there is only 50 liters of oil in the carriage, but the amount of oil can be increased by 60 or 70 liters. This is obviously because the gas station is short of weight, which leads to a lot of refueling.

It is conceivable that there is a price difference of 100 ml when adding one liter of oil at a gas station. When refueling at a gas station, there is no way to actually measure how much oil is in the tank because the car is refueling at the gas station. When many car owners refuel, they usually display it according to their fuel meters, and then refuel. If the amount of oil displayed on the vehicle instrument is very small, adding 200 yuan's oil will find that the fuel tank is not full at all. However, because there is no way to measure how many liters the gas station has added, many people question that the gas station will be short of weight.

The problem of short weight of gas stations has appeared, which is obviously a social norm. Although there is such a problem, it may be that people at gas stations consider that when refueling, it is generally because of the rise in oil prices, so they have to adjust. Most people will directly check the number of fuel meters in the fuel tank when refueling, and never notice the number of liters.

The number of gas stations is not accurate. GM people, no matter which gas station they refuel at, can realize that the complaints of gas stations are completely inaccurate. Even if the added oil shows 30 liters, it is found that the number of liters can only reach 28 liters after actual measurement. The difference between the two is two liters of oil, which has caused many car owners to suffer heavy losses. After all, oil prices will feel high when they rise.
