How to put it? In fact, PetroChina and Sinopec are similar, but the quality of oil in different regions is different. You must know that PetroChina and Sinopec cannot rely on one chemical plant to produce oil. In many areas There are chemical plants of China Petroleum and Petrochemicals distributed all over the country, and the quality of the oil produced by these chemical plants is also different. Although the quality is all qualified, if you want to produce higher quality oil, many areas may not be able to meet this requirement. For example, here, Sinopec's oil is better than China Petroleum's. When I drive, I feel that Sinopec's gasoline has a greater power output and is better, while PetroChina's gasoline is average, but I can't say that China Petroleum's oil is not good. Well, I can only say that the quality of China Petroleum in our area is worse than that of Sinopec. I remember the last time I went to Hunan to refuel, I refueled with China Petroleum oil once and I thought it was pretty good. So overall, the quality of China Petroleum and Sinopec The oil quality is almost the same. You can’t say one is better or the other is worse. Just like gas stations in cities and towns, there is a big difference in oil quality. And like PetroChina and Sinopec in Beijing, they are national chemical plants, and PetroChina The oil quality of both companies is very good, so in your own area, you might as well use the oils of both companies and decide which oil is better for you.
