Because the additives needed by China Petrochemical Company are not ordinary additives, but imported additives, which have higher quality in oil quality. Compared with China Petroleum, the gasoline quality of China Petroleum is slightly lower, the composition is not as good as that of China Petrochemical, and the cost is not high. Relatively speaking, the quality of gasoline is low, so the price is slightly lower than that of China Petrochemical.

China petroleum has certain advantages in price, but China Petrochemical is superior in quality and more durable. Some people will try different gasolines and compare them, but it should be noted that China Petroleum and China Petrochemical use different crude oils and different additives, so don't mix the gasolines of the two companies frequently. PetroChina and Sinopec have their own advantages. What kind of gasoline you choose needs to be matched according to the gasoline your vehicle needs, and the right one is the best.

Precautions for automobile refueling:

Gasoline label: There are several kinds of gasoline, and the specific gravity of each kind of gasoline is different, which leads to different performance, so be sure to read the gasoline label carefully before refueling.

Blending gasoline: Some vehicles have higher requirements for gasoline. What if you don't have this kind of gasoline? In fact, mixed gasoline has little short-term effect, but the knock of low-grade gasoline is higher, and other effects are not significant.
