What is the difference between the oil of PetroChina and Sinopec and that of other small gas stations? Which is more cost-effective?

The oil of PetroChina and Sinopec is better, and we don't know the source of supply of small gas stations. Although the oil in small gas stations is cheap, it has an impact on the engine of the car, and even produces more carbon deposits faster, which also has an impact on the three-way catalytic converter [smirk]. Oil quality is different: PetroChina and Sinopec are both leading large gas stations in China, and most people prefer to add Sinopec and PetroChina. Although the price is high, many people are still willing to add it. Because of the quality of crude oil, one is to use large domestic oil fields and the other is imported crude oil, and the refining technology is the best in China. But most private gas stations buy gasoline from local or even foreign small refineries. These gasoline have low cost and poor quality, which are harmful to vehicles and the environment. 2. Their scales are different: PetroChina and Sinopec are national chains, including high-speed, but most of the small gas stations will be built in relatively remote places, which can only be seen by frequent car owners. Although it may give people a sense of shanzhai, it also has advantages, that is, it can effectively save expenses and increase profits. He asked for a different price difference. PetroChina is a state-owned enterprise with fewer employees. Therefore, the pricing is relatively high, the oil products of small gas stations are not guaranteed, and there is no brand influence of PetroChina and Sinopec. If we want to compete, we can only sell them at a lower price through price leverage. But oil products are worthy of our attention, and each has its own advantages. Some small gas stations even have better oil products [grin], so everyone's mentality is to refuel [yeah].

Compared with PetroChina and Sinopec, small or individual gas stations are cheaper at first. Small gas stations are about 0.9 yuan cheaper than PetroChina in our local area, followed by oil products. The oil products of small gas stations also meet the national production and marketing standards!

Take our local area as an example. Small gas stations are everywhere, and there is not even a gas station of PetroChina or Sinopec in a town. Why? Because small gas stations also have a good market. Take myself as an example. I have been driving for six years. In my impression, I refueled in PetroChina once and had no other thoughts. I can't even feel its oil so fast and strong. Maybe my car is not good! [yi tooth] [yi tooth]

I used to find a small gas station to refuel when I ran out of gas on the road. Indeed, I have encountered a situation where the rear of the trachea smacked and the acceleration was weak after the inferior oil truck started. I will never go to this gas station again. Now I have been refueling here for more than three years, and the local reputation has always been good. The point is that it is cheaper than PetroChina! I feel that many people have gone into a misunderstanding about refueling at small and medium-sized gas stations in PetroChina. I have also met some drivers whose cars clearly indicate that they can use No.93 gasoline, and they have to go to PetroChina to add No.96 gasoline, saying that adding other gasoline will make their cars feel boring! Some car owners just buy cars and never go to small gas stations of PetroChina and Sinopec. Some car owners will always refuel at small gas stations. There are really many such people!

I have a friend who works in an oil refinery. Once I asked him where to sell your oil. He said that whether it is a personal gas station or PetroChina Sinopec, it is normal to pull oil. In fact, not all small gas stations have poor oil quality. If you are the kind of person who loves cars, you can definitely add PetroChina and Sinopec. You don't care much about cars. It feels like a means of transportation. Find a few small gas stations and compare them several times to choose a satisfactory one. These are personal experiences. Don't spray if you don't like it. Thank you.

Under normal circumstances, the prerequisite here is normal. The products sold by operating enterprises are all qualified products, so PetroChina and Sinopec are no different from all small gas stations or private gas stations. Because the country also has standards for refined oil, right? Then the oil in all gas stations is naturally not much different, and it is within the requirements of the rules, so there is no difference in oil products. In terms of oil price, Sinopec is a few cents more expensive than PetroChina, and PetroChina is much more expensive than all private gas stations and small gas stations. Of course, small and medium-sized gas stations and private gas stations have higher cost performance.

However, many times, China has many reasons. The quality of many small gas stations and private gas stations is difficult to control. This is an important reason. This is also the main reason why many drivers don't go to private small gas stations to refuel. If the quality can be controlled and guaranteed, it can be said that there are basically no PetroChina and Sinopec. Is this simple and clear? In other words, because there is no management of relevant departments, our driver friends dare not use their own cars to test the quality of these small refueling oils. This is the decisive factor. If all products are qualified, then we can vote with our feet, can't we? This is @ Baileyu's opinion and answer, hoping to provide some suggestions and references for this friend.
