How gas stations are graded

The gas station is a refilling station for automobiles and other motor vehicles, retailing gasoline and motor oil, generally for adding fuel oil, lubricating oil and so on.

Automobile refueling stations are divided into three levels:

First-level stations, with a total tank capacity of 121 m3-180 m3, and a single tank capacity of no more than 50 m3;

Second-level stations: with a total tank capacity of 61 m3-120 m3, and a single tank capacity of no more than 50 m3;

Third-level stations: with a total tank capacity of 60 m3 or less, and a single tank capacity of no more than 30

State-owned oil company gas stations: Sinopec, PetroChina, CNOOC on behalf of the

1, Sinopec, as the domestic energy company with the largest number of gas stations, it is China's leading petroleum industry, the quality of their refined oil products compared to the other two state-owned oil company gas stations is better, the gas station facilities are complete, the service is better.

2, PetroChina, it is China's second largest gas station, brand and scale is not inferior to Sinopec, although the quality of refined oil is slightly worse than Sinopec, but their advantage lies in the price of the relative Sinopec will be more popular.

3, CNOOC, as the last of the three state-owned oil companies, the development of the last few years by leaps and bounds, the quality of their oil is quite good, and in the management concept and service consciousness is also more advanced, the only thing is that there are not the first two gas stations open so much.

Private gas stations:

In addition to state-owned oil companies, and foreign-funded oil companies, the number of private gas stations should not be underestimated. According to the statistics on the number of gas stations nationwide at the end of 2014, 33% of gas stations in China are from the private sector. However, these gas stations generally have chaotic management. Oil quality is not the same, there are substandard, and even "black workshop", and in the hardware environment and state-owned gas stations and foreign-funded gas stations a little worse, but in the price is really very than the three major oil companies preferential.

While the government is now cracking down hard on "black oil", there are still some people who are driven by profit to do harm to the "black oil" business. "Black oil" due to adulteration, fake, substandard oil quality, for the car is also a very big harm, slightly lead to the engine carbon buildup, serious, if the fuel system is clogged, so that the car oxygen sensor and three-way catalytic converter failure.
