Which petrol is better Sinopec or Shell?

Both gasolines are about the same, and both are of good quality.

Gasoline. Introduction:

Gasoline (ULP), which is a transparent liquid in appearance, is mainly composed of C4 C10 hydrocarbons, and is divided into three grades: 90, 93 and 95 according to the research octane number. It has a high octane number and excellent anti-knock resistance, and is used in carburetor gasoline engines with high compression ratios, which can improve the power of the engine and reduce fuel consumption; It has good evaporation and combustibility, which can ensure that the engine runs smoothly, burns completely, and has less carbon deposit; It has good stability, is not easy to appear early oxidation and deterioration in the process of storage, transportation and use, and is non-corrosive to engine parts and oil storage containers. On January 14, 2016, China lowered the price limit for gasoline and diesel, gasoline by 140 yuan, and diesel by 135 yuan, equivalent to 90 yuan per liter.

Basic introduction: The product standards implemented by No. 97 and No. 98 gasoline products seen on the market are all enterprise standards. Compared with the products belonging to the GB 17930-1999 standard, it has a higher octane number and excellent anti-knock resistance, and is used in a gasifier-type gasoline engine with a high compression ratio, which can improve the power of the engine and reduce fuel consumption; It has good evaporation and combustibility, which can ensure that the engine runs smoothly, burns completely, and has less carbon deposit; It has good stability, is not easy to appear early oxidation and deterioration in the process of storage, transportation and use, and is non-corrosive to engine parts and oil storage containers.

As an organic solution, gasoline can also be used as an extractant, and the most widely used as an extractant is the mainstream production technology of soybean oil in China: leaching oil technology. The operation method of leaching oil technology is to soak soybeans in No. 6 light gasoline and then squeeze oil, and then after a series of processing to form soybean edible oil.

PetroChina, Sinopec, Shell, which one is more burn-resistant and has better power?

At present, the domestic gas stations are mainly Sinopec and PetroChina, which are "two barrels of oil", both of which belong to state-owned enterprises, and the domestic Shell belongs to the joint venture brand of Shell and Sinopec. Many netizens asked which of these three oils is more resistant to burning and has better power. Today, I will analyze the differences between these oils for you.

Sinopec and PetroChina are currently domestic consumers prefer to add oil, Sinopec's oil basically comes from imports, most of it comes from the Middle East, and most of PetroChina's oil comes from domestic oil fields.

Although the refining technology of Sinopec and PetroChina is not much different, there is still a slight difference, and Sinopec uses imports, so it is relatively high, but it can be determined that Sinopec and PetroChina, as state-owned enterprises, will not blend, and can be guaranteed above the national standard.

Shell's oil basically comes from Sinopec, but vpower additives will be added, which can clean the engine and do not deposit carbon, so it is difficult for consumers to see similar fuel sales at Shell's gas stations.

According to the feedback of netizens, the Shell oil with VPow added is more resistant to burning and has more power, but some netizens think that Shell is not as good as two barrels of oil, and the engine will light up red after adding it. In fact, in No. 95 oil and above, additives will be used in each oil, additives will indeed affect the use of oil, but in fact, the effect will not be particularly obvious, many times it is just the psychological effect of consumers.

If there is a high demand for oil products, it is recommended to choose Sinopec or PetroChina, although these two are state-owned enterprises, and in a monopoly position, but their standards for oil products are quite strict, so you can buy with confidence. As a joint venture, Shell is not as strict in regulation as Sinopec and PetroChina, so it is difficult to ensure the safety of oil products.

Lack of vehicle power, etc.! As you know, in the past, when the chemical industry was in power, PetroChina was mainly engaged in the north, while Sinopec was mainly engaged in the south, and PetroChina's main business in the past was oil extraction, while Sinopec was mainly engaged in oil refining. Therefore, Sinopec's refining and chemical units are more and more advanced than those of PetroChina, so theoretically Sinopec's oil quality is better.

Sinopec, PetroChina, Shell's diesel, how to say this, these three are the world's top 500 enterprises, if the product quality is not up to par, it is difficult to gain a foothold in the world, so which oil to add is mainly based on whether it is convenient for themselves and in line with their own habits. The quality of the product may be good for these indicators and good for that one, and the products have their own advantages and disadvantages, but the products must be qualified.

1. Petroleum products have flammable, explosive and easy to accumulate electrostatic characteristics;

2. Fireworks are strictly prohibited in the station;

3. It is strictly forbidden to engage in operations that may produce sparks in the station;

4. It is strictly forbidden to slap chemical fiber clothing in the station;

5. It is strictly forbidden to fill gasoline directly into plastic containers;

7. It is not allowed to carry dangerous goods;

8. Mobile phones are prohibited in the station.

Components:

The fuel dispenser is a fuel metering device that directly refuels a motor vehicle. It forms a complete oil supply system with oil tanks, pipelines, pipe fittings and valves. The fuel dispenser is composed of four assemblies of oil pump, oil and gas separator, meter, counter, as well as some other components such as motor and oil gun, and any type of fuel dispenser can be regarded as composed of this large assembly and some other simple components.

There are many types of fuel dispensers used in gas stations, ranging from mechanical and electronic to computerized automatic dispensers. The flow rate of the fuel dispenser can be divided into 50-60 liters and 80-90 liters. The small flow refueling machine is suitable for refueling cars and vans; The high-flow refueling machine is suitable for refueling large buses and container trucks.

The basic structure (mechanical transmission part) of various fuel dispensers is consistent. The difference between mechanical and electronic is the difference between digital display devices, and the electronic type can be used with a microcomputer to achieve the purpose of automatic operation. There are two types of fuel dispensers used in China: above-ground fixed fuel dispensers and suspended fuel dispensers.

The stationary refueling machine can make the location of the car clear, the procedure of refueling operation is not easy to be confused, the work efficiency is high, the first is cheap, the failure is less, and it is easy to maintain. However, it covers a large area, the refueling range is small, the vehicle must be refueled within the predetermined range, limited by the self-priming capacity of the self-priming pump of the refueling machine, the distance from the underground oil tank shall not exceed 20-25 meters, and the suction height is 4 meters, otherwise it will affect the refueling of the refueling machine.
