Why do people in the industry say that the oil quality of Sinopec is higher than that of PetroChina?

I am not an insider, so I have no say in the oil products produced and sold by domestic oil companies. But since someone has raised such a question, let me talk about my humble opinion.

In terms of crude oil sources, Sinopec has few oilfields and mainly relies on imported crude oil. The external dependence of crude oil demand has remained above 55% for a long time, and this proportion has increased in recent years. There are many oil fields in PetroChina, and the crude oil produced and exploited is basically self-sufficient, with less imported crude oil. Because the sulfur content of foreign crude oil is higher than that of domestic crude oil, there will be differences in refining technology, process flow and method.

At present, there are two popular crude oil refining methods in the world, namely catalytic cracking and hydrogenation technology. Due to the different sources of crude oil refined by Sinopec and PetroChina, the two companies have different refining methods. PetroChina adopts the catalytic cracking technology widely used in China, while Sinopec gradually adopts the more advanced hydrogenation catalytic technology abroad besides the catalytic cracking technology, which makes the produced oil products more in line with the national V standard in terms of quality performance, explosion resistance and combustion performance, which is more conducive to the improvement of environmental protection and ecology and promotes sustainable development.

Among the 54 refineries above domestic scale, Sinopec occupies 37 of them, which shows that Sinopec has obvious advantages in the domestic refining sector. Generally speaking, strength represents everything, and strength represents the future and hope. It is precisely because of the differences in refining technologies and methods and refining additives that the oil refined by Sinopec seems to have more advantages in terms of combustion efficiency (flame resistance), antiknock performance (comfort), quality performance (quality), fuel consumption per kilometer, etc., but this advantage is not obvious and should not be susceptible.

If people in the industry say that the oil quality of Sinopec is higher than that of PetroChina, of course, different people have different opinions. Is that really the case? It seems that only consumers can realize it in practice.

Hello! I have worked in Sinopec's gas station for ten years!

Actually, it depends on who the insider talks to. When you talk to laymen, you must say that Sinopec's oil is better than PetroChina's, including me in front of customers, and of course you must speak for your company.

However, when people talk to insiders, they don't say so. The quality of oil mainly depends on the quality of refinery. For the same crude oil, the refineries in Hangzhou are inferior to those in Shanghai. This is the technological gap, and so are PetroChina and Sinopec. You can only say which refinery the oil used in your area is from, and who is good and who is bad.

Many of us have many opinions on oil products, and even some amateurs dare to copy an article online to answer. This is irresponsible. In fact, we don't have to care too much about the oil quality of these two state-owned enterprises. Now there are strict management systems and factory standards, so we basically don't have to worry about the oil quality of these two companies.

I'm an insider. I used to work in the safety and quality department of Sinopec municipal branch. Objectively speaking, there is no problem with regular Sinopec oil products, and the difference lies in management.

There are few joining stations of Sinopec, and the years when PetroChina robbed the gas station resources were just those years when it was just split. As long as it buys oil, it can hang the brand logo of PetroChina. At the same time, the management of the self-operated station is extremely loose, and the stationmaster who gets up early has the right to buy. Some gas stations purchased a car full of petroleum products, equipped with three cars for refining, and even did not purchase regular oil for a whole month, which led to the complete destruction of the PetroChina brand. At the same time, due to poor management and poor awareness of intellectual property rights, a large number of counterfeit gas stations have appeared.

Since the year of 20 10, PetroChina has gradually strengthened its management, which has gradually changed the above situation and improved.

Therefore, if you see the brand of PetroChina but can't use the PetroChina fuel card, they are all fake gas stations, which is also the most reliable identification method.

There are different opinions on this issue. Some people say that the oil quality of Sinopec is higher than that of PetroChina, while others hold the opposite view.

I am in Guangdong, and I want to talk about my subjective feelings about using oil in the process of car use. The first thing that can be confirmed is that the oil products of different companies are different. As for how big the difference may be, it needs to be carefully distinguished by professional instruments. I just want to talk about it from my personal feelings. The first car was a domestic car, and it was always refueled by Sinopec. On the way back to my hometown, I once found a private gas station, which not only discounted but also washed the car for free, so I added 95 # gasoline. I didn't feel any difference from Sinopec the first time, but I added it the second time. This time, I obviously felt different. When the car was at 60 speed, I felt that the car could not eat oil for a short time, but I was driving.

Later, because I needed to send my son to a junior high school far away, I found many gas stations in PetroChina on the way, and they went in with a try attitude. Petrochina gas station saw that I didn't have their fuel card, so it recommended me to get a fuel card and send a 20-yuan fuel coupon for the first time. I will give 0.2 yuan a discount every time I refuel. It looks really good. PetroChina is also state-owned, and its quality should be good. So I applied for a fuel card of PetroChina. 0.2 yuan has a discount for every gasoline, and almost all of them use PetroChina's gasoline, so it doesn't feel any different from Sinopec's.

At the end of last year, I changed to a domestic SUV, and I have been adding oil from PetroChina. Because this SUV weighs 1.7 tons, it feels quite expensive. Officially, it is 7.5 liters per 100 kilometers. The actual test fuel consumption is about 65,438+00 liters per 100 kilometers. The fuel gauge of the car shows about 9 liters, so you should refuel every 400 kilometers or less. Every time it adds up to about 230 yuan (.

This year, I went to go on road trip with my friends, and filled up 95 # gasoline at Sinopec gas station before I got on the expressway. It took me 182 yuan. Then visit Huangyao Ancient Town and Guposhan, fill up Sinopec 95 gasoline in Guangxi, then go to Wuzhou to see the arcade, then go home and fill up 240 pieces of Sinopec 95 gasoline, and go back and forth.

Since I came back from my trip to Guangxi, I have been adding Sinopec, taking the same road as before. The obvious feeling is that the fuel gauge shows less than 8 liters and the actual fuel consumption is 8.5 liters. I think this is the real fuel consumption performance of this car. This change in fuel consumption may be related to the running-in period of engine oil or cars.

Mom is from Sinopec. She said there is no difference in oil products, they are all the same.

We also talked about this two days ago. She didn't have any suggestions about oil products, but suggested not to buy fuel treasure and sold it to you. The oiler gets a commission, a bottle comes down, the gas station gets a commission, and the oiler gets a commission. The amount is not small, so this thing doesn't have much money.

Many Sinopec gas stations are privately contracted, but oil products are still in formal channels. It used to be a mess, and all kinds of messy oil products could appear. Now the management is strict, and private people dare not do too much. After all, it is a gas station or a cash cow.

The best way to distinguish Gui Li Sinopec from PetroChina is to use oil cards. The oil card is officially issued, and the private oil receipt card is completely at a loss. They will not accept this thing.

Someone has done an experiment on this: "A new car of the same model is added with gasoline from No.95 Sinopec and PetroChina, and the added amount is the same. Then the same person drives the same distance on the same road, and the driving situation on the road is similar (although there are some gaps, the gap is not big). The final result is that Sinopec's gasoline is about 30 kilometers more than PetroChina. "

Did you get the right result? So why is this? Let me introduce it to you.

First of all, it should be noted that both enterprises are state-owned enterprises, and there is no difference in corporate background. The biggest difference between them is that the additives added in the source oil and source refining of PetroChina and Sinopec are different.

Everyone knows that the source oil of PetroChina is made in China and that of Sinopec is imported.

As for the refining method, you can refer to the national standard of motor gasoline.

The quality problem of gasoline closely related to our common people is which gasoline is more resistant to burning, in other words, which gasoline will go further without affecting the car?

The problem of fire resistance is actually related to the density of gasoline. According to China's regulations, the quality index of gasoline density must be between 720 and 775. According to this standard, the maximum density difference between the two will not exceed 50, so there is not much difference.

According to professionals, the real quality gap between Sinopec and PetroChina is closely related to the local crude oil refining methods and gas stations.

Therefore, the specific quality should be determined according to each batch of oil, which has nothing to do with the difference between north and south and the temperature difference.

But these two days, I added 95 from Sinopec and 95 from PetroChina respectively. The former is around 5.8 and the latter is around 6.0.

I suggest that there is no problem in adding Sinopec to the south. I have never been to the north.

This question is unscientific.

PetroChina and Sinopec are both large state-owned energy enterprises. The quality of oil products shall comply with the unified standards formulated by the national quality inspection department.

Most of the oil fields in China belong to PetroChina, so PetroChina is the main force of domestic crude oil exploitation, and a few refineries will also refine the exploited crude oil into refined oil.

Many large refineries in China belong to Sinopec, so Sinopec is the main force of refined oil production. Sinopec has few oil fields, and PetroChina will transport a large amount of crude oil to Sinopec every year.

PetroChina and Sinopec will also import foreign crude oil for refining to produce refined oil, and the quality of oil products is determined by many factors.

The refining process of crude oil is the main factor that determines the quality of petroleum products.

The two departments process refined oil, and each label is in accordance with the unified standards stipulated by the state. There are strict quality and quantity inspection procedures, so there should be no difference in the quality of refined oil.

As an individual refueling, we must first identify whether it is a gas station of PetroChina or Sinopec. Because individual gas stations are packaged almost like them, you can't tell without looking carefully. Some individual gas stations, in order to increase profits, will enter the refined oil of small refineries, and the quality is definitely different from that of large refineries.

State-owned gas stations should always be inspected by higher quality and measurement supervision departments, and the quality and quantity of oil products are guaranteed, so you can rest assured.

I feel that this statement is misleading. I guess the reason for this statement is from the source of crude oil.

As we all know, China is already the largest importer of crude oil. Except for less than 200 million tons of domestic crude oil, more than half of it is imported, mainly from the Middle East. Judging from various data, the quality of imported crude oil is better, while domestic crude oil contains more impurities such as sulfur, which is the difference. In China, the early stage of two barrels of oil was mainly domestic crude oil refining, that is, China Oil. On the contrary, China Petrochemical tends to use imported crude oil. (In fact, there is also a China offshore oil company, which mainly goes abroad to exploit oil, and there is not much oil refining in the initial stage. The market statement should come from this!

But we find that there are two fallacies in this statement:

One or two barrels of oil, even CNOOC, did have a clear division of labor at the beginning of its establishment, but with the development of society, the state gradually liberalized various businesses. Now three barrels of oil can develop refining business, and besides domestic crude oil, it can also import crude oil. From this perspective, we can find that where imported crude oil is used really depends on the region. China's crude oil production is mainly in the north and northwest regions, and there are basically no oil fields south of the Yangtze River. In other words, if it is in Guangdong, no matter which company, refineries will tend to use imported crude oil. After all, the cost of shipping is cheaper than that from the northwest and northeast, and the crude oil from the north and northwest may not be enough for local use. Why transport it?

Second, in refining gasoline, raw materials are often not the key, but more importantly, process and quality control. So the quality of the two barrels of oil is up to standard, and the difference will not be too obvious. However, there may be some differences between refineries in different places, which is the key to affect the quality of gasoline, although the impact is not great. Factory technology, testing level, etc. How do you test as a consumer? What's the difference? It is good to meet the national standards.

Generally speaking, the two barrels of oil are large state-owned enterprises, and the quality of oil products can be guaranteed and trusted, so there should be no big difference. Don't worry, the country will have an annual inspection, care about fuel consumption and pay more attention to the maintenance of its car!

The oil of PetroChina is transparent and basically colorless, while the oil of Sinopec is yellowish. I saw on TV that foreign gasoline is basically colorless and transparent, so I have been refueling in PetroChina, and they can use credit cards, recharge and have discounts. In 2006, PetroChina was added to the classic car. It has been more than five years, and the annual inspection tail gas is still disposable, so I trust PetroChina. .

I am a grass-roots employee of PetroChina and have worked in PetroChina for 20 years. PetroChina and Sinopec are the two largest refined oil sales enterprises in the market. Although they are competitive in the market, the quality of their respective oil products is absolutely trustworthy. Both are purchased from state-owned refineries, and the quality is absolutely guaranteed.
