How about Anhui Expressway Petrochemical Oil?

Anhui expressway petrochemical oil is very good. The quality of petrochemical oil is completely acceptable and can be used with confidence. The gasoline in the high-speed service area and the gasoline in the gas station below are uniformly distributed by companies in Sinopec, and there is no difference. Sinopec and PetroChina have different gasoline producing areas. Generally speaking, Sinopec mainly uses imported oil, and most of PetroChina's oil comes from China. Sinopec will add imported additives, which will be higher in density and relatively more flame-resistant.
