Why doesn't the master of the garage let you go to the private gas station to refuel?

Why does the garage master refuse to use gasoline from private gas stations?

Why does the garage master refuse to use gasoline from private gas stations? The fuel price of private gas stations is cheaper, but it is not necessarily inferior or fraudulent. From the process point of view, refueling at private gas stations can save a lot of traffic costs. In private gas stations, the goods are directly purchased from some local refineries, and the oil trucks here send the oil to the oil depot.

Oil can be sold directly there; Private pumping units employ fewer people, generally two or three people are enough, so the cost is low and they can be sold to suppress oil prices. They don't know the basic situation and are at risk of problems (not necessarily, but possible). When refueling at a private gas station, it is difficult to defend rights when there is a problem because you can't tell right from wrong.

You can learn about the situation from well-known private gas stations; Inferior gasoline contains impurities, gasoline burns incompletely, and all impurities are dirty on the cylinder and intake valve, which looks almost black. If you don't handle this properly, it's hard for you to wait until these black impurities burn into carbon at high temperature.

Then driving is even more wasteful, the car is boring to drive, the ignition is not good, and there will be many problems. Take cheap engine oil as an example, you can go to the gas station to refuel as long as the car is not broken, but the problems such as poor power, increased carbon deposition, black smoke, clogged filter elements and even air pump combustion are random, depending on your luck.

Sometimes the fuel tank is burnt out and the car is not broken, so it is no problem to change the oil. I still feel that the oil is good after burning, and sooner or later there will be problems when it is full. Refueling is not recommended after that. Seven or eight small gas stations have been changed, and most of them are not good. Obviously, the experience is very different, the running distance is short and there is no comparability.

It's good. Remember, I'm talking about most gas stations. Don't blindly trust these small gas stations. The price per liter is about 4. 10 yuan, while the selling price is 7.00-8.00 yuan. The retail profit can be imagined. Even if the consumption tax is about 1.5 per liter, many enterprises are salivating for profits. This is why small gas stations compete at low prices.

However, there is little difference in oil quality between local refineries and central enterprises. You can use it safely. As for the short weight and weight of cats, that is another matter. I have a Sinopec fuel card with money in it. Whenever I go to a strange city, I always fill it up first. It's not that I don't trust private gas stations, but I'm afraid of encountering probability problems.

When oil poisoning occurs, the fuel system of the whole vehicle must be cleaned, the fuel tank must be emptied, and then new gasoline must be filled. In more serious cases, the three-way catalyst and oxygen sensor should be replaced. The oil quality of private gas stations is uneven and unstable, and there are too many impurities, which are often mixed with various things. If used for a long time, the air pump will be blocked or corroded.

My friend in the auto repair shop was repairing several Wuling trucks and Chang 'an. Due to long-term refueling from private gas stations, the gas stations were corroded and damaged. The most direct damage is carbon deposition! Due to the high impurity content of inferior petroleum products, petroleum products can not be completely burned, impurities can not be effectively removed, and carbon deposits are directly formed.

You should know the harm of carbon deposition to cars. If it is too much, the damage to vehicle parts will be great. Second, private gas stations are fake and shoddy. First, it is difficult to approve the procedures of gas stations. If you use particularly inferior oil, it is illegal and the gas station will be confiscated. If you only provide inferior petroleum products, you can earn more.

Drivers nowadays are not fools, such gas stations can't survive at all, and the high gas station procedures or contracting fees have been eliminated! But if you are a high-end car, you won't care about the price difference. Just go to the big gas station, because it will add 95/97. If you want to go to a fake small gas station, the general method is to use No.92, change or add No.95 oil! As long as the price is not too low and the environment is not too bad. If you really think oil is expensive, you can consider the price of natural gas.
