Many car owners will choose to go to private gas stations to refuel because the price is particularly affordable, but other car owners are very afraid to go to private gas stations to refuel, thinking that cheap goods are not good. In fact, when we go to an auto repair shop, the master usually advises not to add oil from private gas stations, because the oil from private gas stations comes from refined oil produced by major low-cost companies, and its oil quality is good or bad. If it is oil with incorrect purity, it will cause damage to the vehicle. At the same time, there are many routines in private gas stations, which will also harm the interests of some car owners.

Petrochemical, Petroleum and now Shell gas stations all have fixed oil suppliers and standardized refining processes, and overall, the oil products are relatively qualified. Private gas stations have no fixed suppliers, and the stability of quality will definitely be biased. The most common problem is insufficient weight, and low-grade oil is sold at high-grade prices. Like taxi meters, private gas stations are sometimes empty. Originally, 30 liters could be filled, but he went to give you 40 liters, which caused some damage to the consumer's economy.

In addition, some private gas stations will mix fuel and add alcohol-based fuel to gasoline at the ratio of 1: 1, but the price of alcohol-based fuel is less than half that of ordinary gasoline, which is very non-combustible. If the average car owner adds this blended fuel, he will find that he runs a lot less mileage than the normal fuel. And some private gas stations, for the sake of profit, will also make an idea on the gasoline label and sell No.92 oil as No.95, thus earning a wave of price difference. In fact, it would be nice to take a shot once in a while for the last time, but if the oil is not good, it will do some harm to the car.

Therefore, even if the oil in private gas stations is 2~3 yuan cheaper than that in ordinary gas stations, people still try to go to regular gas stations to refuel. Because once you meet an unscrupulous dealer, the owner will not only save any money, but also be cheated, especially if the car is injured, the loss will not be a little bit.
