Does using fuel from different gas stations affect the car?

[EmmaAnn]

Fuel from different gas stations can be mixed as long as the octane rating is the same, but it is important to refuel at reputable gas stations. Specific details are as follows: 1. Minimal differences: Fuel from different gas stations does have some variations because the sources of the fuel differ. However, refineries produce fuel according to national standards, so even if the octane values vary slightly, the differences are not significant. 2. Fuel sources: In China, gas stations are predominantly operated by Sinopec and PetroChina. In terms of fuel quality, Sinopec > PetroChina. Firstly, PetroChina has relatively more gas stations, mainly concentrated in northern China, and most of its oil comes from domestic oil fields. On the other hand, Sinopec is mainly concentrated in southern China, where domestic oil fields are relatively scarce, and it primarily refines imported oil from the Middle East.
