Some unknown gas stations have low oil prices. Is it because the oil is mixed with water?

Basically not, because there are regulatory authorities to check from time to time, if there is water mixed, it is easy to find out, and the procedures and processes for opening a private gas station are very complicated. If the oil is found to be mixed with water, it will be ordered to stop work for rectification, or even shut down, and the cost is very high, which is not worth the loss.

Private gas stations have low oil prices because of competition. China's two barrels of oil, Sinopec and PetroChina, occupy almost most of China's market. Private gas stations need to snatch food from others and grow in the gap, so they have to lower their prices to compete with them. And found that some private gas stations often send small gifts to warm customers. In fact, it is still profitable to do so. After all, its cost is low. Generally, they are located in relatively remote areas, with small floor space and simple facilities, and the staff are mainly family members. If these costs are reduced, the price can be reduced to attract customers, which is still profitable.

Although small gas stations don't mix water, there is no guarantee that their oil products will be really fine. Some may be imported through formal channels, and some may be refined locally. The quality is still uneven, at least not reassuring. Moreover, because of the small passenger flow, gasoline is prone to produce chemicals over a long period of time, and the quality of oil products will decline, which is harmful to the car. For example, some oil will consume more energy, or the engine will make a lot of noise after it is added, which will often lead to such problems, so it is very important to choose a good gas station.

Although some small gas stations are very cheap, there is still no oil with guaranteed quality. You don't know which channel it comes from. If it works once or twice occasionally, it is likely to cause problems after long-term use. After all, although there is a regulatory part, you will still rack your brains if you want to take advantage. For safety reasons, it is best to add regular PetroChina and Sinopec, which are basically stable distribution services with guaranteed quality and rest assured.
