What is the quality of No.93 gasoline from Jinan Huada and Chengda?

Huada's oil is ok. I used to add it often. Cheap can also be used up. Chengda, at the southern end of the chemical fiber factory, is said to be quite cheap. It has never been used and will not comment. There is also a Chengda on Gongye South Road to the west of Chongqing Little Swan, and it has also been added there. Oil is not expensive, but it doesn't count. I wonder if it's the same as a chemical fiber factory. I think the gas station in the northeast corner of East Outer Ring Road and Gongye South Road is the best place to escape. Now the oil price is 5.74, and the oil at the east exit of Heping Road is not good. You still can't get out.
