4hw.com.cn: for the car owners, it's believed that gas is the most common thing for car owners. However, many people often say that there are many greasy things in gas stations, so we must pay attention to them when filling up. But are the rumors true? What's wrong with refueling? Let's take a look at the six most common mistakes of automobile fueling with Xiaobian.
Myth 1: wait until the car runs out of gas
A lot of kids are used to waiting until the oil meter light comes on to refuel. In fact, it's really unnecessary to do so, because the gas station can be found when you really want to find it? Besides, the oil pump of some models is designed in the tank. The gasoline in the tank has the cooling effect on the gasoline pump. If you always wait until there is only a little left to refuel, the cooling effect on the oil pump will be lost, which will always accelerate the aging of the gasoline pump.
Mistake 2: it's a problem to continue adding after refueling and jumping gun
Many people think that they can continue to refuel until the gun jumps, or even jump for the second time, so there must be a problem, that is, there is a cat greasy. In fact, it's not the case. The fuel gun is equipped with a sensor, which is very sensitive. With the refueling, when the oil and gas in the fuel tank are pushed upward, the approximate full pressure will be increased, and the gun will jump when it reaches a certain level. For example, if you add 100 yuan or 200 yuan of oil, the staff set a good amount of oil, and then the gun will jump after adding the set data, which also means that the refueling is over, and it is not necessary to wait until the oil is full to jump the gun.
Mistake 3: the fuel quantity exceeds the rated volume, which is too greasy
Many people don't understand why their fuel tank is clearly 50 liters, but the fuel can be added to 55 liters. Therefore, it is doubted that there is a problem with the data of gas stations, and there is something fishy about it. In fact, this kind of rumor is not right. Xiaobian is not talking for gas stations. In fact, the fuel tank volume calibrated by many vehicles is not the actual fuel tank volume of the vehicle. For the sake of safety, the manufacturer always leaves a margin of 10% to 15% in the manual, so 55 liter fuel tank can be added to 55 liter fuel tank.
Error 4: adding half tank oil is more fuel efficient
The fuel consumption of a car is really related to the weight of the car body, so many people think that the car body is heavier when it's full of fuel, and it's more fuel-efficient when driving. The car body will be lighter when it's half filled with fuel, and it'll be more fuel-efficient. But we didn't think that the solvent in the fuel tank of our vehicles is about 60 l, and the extra dozens of L is no more than dozens of kg, which can be ignored for more than a ton of vehicles. But it's a waste of time to run a few more times with half a tank of gas. It's annoying to catch up with the traffic jam, isn't it?
Myth 5: it's cheaper to refuel at night
There are a lot of articles on the Internet that are more economical to refuel at night. The basis is the expansion of heat and contraction of cold. Using the temperature difference between day and night, we think that more oil can be added at night. It's not surprising that the oil depots for refueling are all built at the bottom, and the constant temperature state is guaranteed. No matter in hot summer or snowy winter, the temperature of the oil is the same, the volume of the oil is naturally unchanged, and the amount of money and oil are the same.
Myth 6: gas workers can steal oil by shaking their hands
Many people see that when the refueling staff is about to finish refueling, they will hold the oil gun with their hands and "click" several times on the valve. The number on the fuel dispenser will jump faster. It is likely that the oil is not enough at this time, so they think this link is too greasy. Of course, if it's an irregular gas station, it may not be guaranteed. In fact, there are many links for an irregular gas station to hide its felicity.
Regular gas stations do not pass the price inspection of the metering Bureau, and the error is only allowed to be between 1 / 1000 and 3 / 1000. There are also lead seals on the oil meter. Once the price or oil quantity is entered, it will not change. If the oil gun is changed privately, it will be invalid. And when the gas workers settle accounts, they always settle according to the backstage pump code, which has nothing to do with it, so it's better to go to a regular gas station for gas.
