First, put the money into the slot, and slowly swallow the hundred-dollar bill. The message "XXX.00 Yuan" immediately appeared on the LCD screen of the self-service tanker.

Select refueling type 93, 97. Lift the oil gun, press the key to select, then insert the oil gun into the oil receiving port of the oil tank, and the tanker starts to refuel.

After about half a minute, the oil was filled up. After the oil gun is put away, the tanker prints out a small ticket with detailed information such as refueling time, oil type, currency amount and refueling liter. The whole DIY refueling process only takes two minutes.

The staff said that once the fuel tank is full or the consumer stops refueling, the refueling gun will automatically turn off to avoid fuel injection. The self-service tanker is also equipped with static elimination equipment. Owners only need to press the handprint on the tanker to eliminate static electricity, making self-service refueling safer.

Most drivers can quickly complete self-service refueling under the guidance of the staff. However, some drivers believe that "self-service refueling is not as good as tradition, and you have to get off the bus yourself in such a hot day."

In the past, all you had to do was pay for gas, and then all the things were helped by the staff. Drivers who use cash now have to go to convenience stores to change money with receipts.

2. What are the misunderstandings of refueling in automobile common sense?

Experts pointed out that at present, consumers don't know enough about the performance of high-grade gasoline, and they don't choose gasoline according to the compression ratio of the engine, which leads to the serious problem of early scrapping of automobiles.

60% of the cars scrapped in advance are caused by the wrong oil. According to the staff of Xiaoyun Road Gas Station of CNPC Shouqi, a considerable number of vehicles coming to refuel use low-grade gasoline, such as Santana with engine compression ratio of 8.7-9.0, and even Santana 2000 and No.90 unleaded gasoline with compression ratio of 9.5 are still widely used.

Lin Deming, sales manager of PetroChina Shouqi, told reporters that many car owners did not really understand the compression ratio of their cars before using them. For example, 90 # gasoline is used when the compression ratio is below 8.0, 93 # gasoline is used when the compression ratio is between 8.0 and 8.5, 95 # gasoline or 97 # gasoline is used when the compression ratio is between 8.5 and 9.0, and 97 # gasoline or 98 # gasoline is used when the compression ratio is between 9.5 and 68. Low-grade gasoline oil experts told reporters that many car owners lowered the standard oil for convenience or money saving.

Although most modern automobile engines are equipped with knock sensors and can use gasoline with lower octane number, the ignition angle must be readjusted. However, doing so will increase fuel consumption and power loss.

Due to the low gasoline grade and insufficient antiknock performance, the engine will knock, the power will be reduced, the emission will deteriorate, and even the engine will be seriously damaged. At the same time, using low-grade gasoline will increase fuel consumption by about 5%.

Therefore, in the long run, long-term use of mismatched low-grade gasoline will save money on the surface, but actually increase fuel consumption, reduce engine performance, increase maintenance costs and shorten automobile life. .

There are several details that you need to pay attention to when you refuel the car.

I still remember that during the 2008 Beijing Olympic Games, all China people would say "Come on China, Come on Beijing" to cheer for their motherland.

What kind of oil do you want? Why should you shout "Come on" to the athletes in your own country when watching the game? Foreigners are puzzled. In fact, the word "refueling" in our mouth means that foreigners "fight", and their understanding of "refueling" is literally "refueling", which is probably like this: When it comes to the small matter of refueling, what the automobile industry wants to ask is, will you really refuel? Do you all know some details about refueling? Pay attention to the gasoline label first.

Let's start with the most basic gasoline label. Gasoline label refers to the ratio of antiknock performance of actual gasoline to that of standard gasoline.

The higher the label, the stronger the explosion-proof performance. Vehicles with high engine compression ratio need high standard gasoline.

Can different grades of gasoline be mixed? Yes, but not recommended! The owner still needs to add gasoline correctly according to the car manual or the logo on the fuel tank cover. Because of the compression ratio, cars using high-standard gasoline need gasoline with good antiknock performance, and using low-standard gasoline will cause engine cylinder knocking.

A car with low-grade gasoline will not knock even if it is added with high-grade gasoline, but it will also accumulate too much carbon due to insufficient temperature and pressure in the cylinder. After popularizing the use of gasoline labels, let's talk about some details that we should pay attention to when refueling cars.

Can you continue to refuel after the rush? When many people refuel, there will be a situation where the fuel money is not an integer after the jump. In order to collect money or change, the staff at the gas station will habitually pull out the oil gun and put it back in the tank to refuel, so that the oil money can be enough.

This is not recommended by the automobile industry. There is a simple reason. If it's in hot summer, you will continue to fill up the gas tank after running. I believe everyone understands the principle of thermal expansion and cold contraction.

With the increase of temperature in the fuel tank, the volume of gasoline gradually expands. However, because the fuel tank has been added to the fuel filler and there is not much space, the fuel tank may be damaged with the gradual increase of expansion pressure.

Of course, the current automobile fuel tank will be designed with vent holes, and when it is too full, the oil will be spilled out through the vent holes. However, if the vent hole is blocked, negative pressure will be generated in the fuel tank, which will lead to poor or even no oil supply.

There will be a situation that the engine will not catch fire when it is just filled with oil, or the cylinder will jump when driving at high speed, which may be caused by the tank being too full. Is fuel additive necessary? Many consumers will be forced to sell fuel additives by the staff of the gas station when they go to the gas station to refuel.

Most of the fuel additives on the market slogan "Clean combustion, improve engine carbon deposition". Are they false advertisements? No, most fuel additives (cleaning, octane number adjustment, synthesis, etc. ) is a substance that can remove deposits from automobile engines. However, we need to understand that fuel additives can only play the role of daily maintenance in the fuel system of vehicles. Many vehicles will have problems such as unstable idle speed, poor acceleration, stuffy cars, shivering air conditioners when loading cars, excessive carbon deposition, lack of cylinders, and increased fuel consumption. Most of these phenomena are related to the unclean fuel system.

However, fuel additives can only reduce the generation of engine carbon deposit. In order to fundamentally solve the problems such as carbon deposition, everyone still needs to go to the 4S shop for maintenance. In general, there is no need to use fuel additives.

However, when high-grade gasoline cannot be found in remote areas, fuel additives (octane number adjustment type) are necessary. Can the engine oil be mixed? After talking about fuel series, finally talk about engine oil.

This liquid not only plays the role of lubrication in the engine, but also has the functions of cleaning, rust prevention and cooling. Mixed oil phenomenon, there will still be consumers who are greedy for cheap for a while and will mix different oils together.

This is not desirable! Because different brands and specifications of engine oil additives have different components, it is easy to form deposits when mixed together, which is not good for engine lubrication. As for determining the engine oil model, checking the oil quantity and changing the engine oil regularly, it is a cliche, and it is not a waste of ink to talk about the vehicle industry.

Obviously, there are many details worthy of our attention in the little matter of "refueling". I believe everyone will take good care of their car, but don't take it for granted in this matter. It is better to maintain your car scientifically and reasonably.
