Is China Oil Union a legitimate gas station?

[LaylaLee]

Legitimate, but it is recommended to refuel at large gas stations such as PetroChina. The differences between Oil Union and PetroChina are as follows: 1. Different origins: China United Petroleum Co., Ltd. is a petroleum foreign trade company jointly established by China National Petroleum Corporation and China National Chemicals Import & Export Corporation; while Sinopec is a super-large petroleum and petrochemical enterprise group reorganized and established by the state in July 1998 on the basis of the former China Petrochemical Corporation, a state-owned company solely invested by the state, an authorized investment institution, and a state-controlled company. 2. Different regions: Oil Union has more oil fields; Sinopec has more refineries. "PetroChina" and "Sinopec" are basically divided into "north" and "south". That is, the north is the territory of Oil Union, and the south is the territory of Sinopec. However, the situation has changed in recent years, just like China Netcom and China Telecom began to move south and north.
