Is it better to use 92 oil or 95 oil for cars

Recently, some netizens posted, saying that No. 95 gasoline is not only pure, but also good for the engine and has a long mileage. Automobile experts said that the gasoline label has nothing to do with the purity of the oil, and which grade of gasoline to add should be decided according to the actual situation of the car, and cannot be "blindly high".

Lin Kechun, deputy director of the Automobile Department of Fujian Shipbuilding and Transportation Vocational College, said that the most advanced gasoline labels on the market are calibrated with the octane number of gasoline, which represents the anti-knock property of gasoline. "The higher the fuel grade, the slower the combustion rate of the oil, the less deflagration is required, and it is suitable for engines with higher compression ratios, and vice versa. ”

Lin Kechun said that the standards for the content of sulfur, manganese and other substances in No. 92 and No. 95 gasoline are the same, and there is no relationship with the purity and quality of the oil.

The car owner chooses the gasoline label is not as high as possible, and it is best to choose the oil according to the compression ratio of the oil label and the engine recommended on the car's own manual. If the instruction manual requires the use of No. 92 gasoline and the owner adds No. 95, then the high anti-knock advantage of No. 95 gasoline can not be brought into play, and there will be a 'stabilescence' phenomenon, that is, the engine compresses to the end of the oil has not reached the spontaneous ignition point, resulting in incomplete combustion of gasoline, resulting in pollution and waste, but can not play a fuel-saving effect. Guo Xinying, director of the petrochemical office of Zhangzhou Quality Inspection Institute, said.

Refueling and adding oil to the car generally all cars have a rated standard, as long as it is greater than or equal to a certain number, normally speaking, ordinary cars can add more than 92 oil, but some imported cars or joint venture cars have regulations on the number of oil to be greater than or equal to 95 balls, so that is to say, it depends on the sign of your own car, of course, if you have a higher number, it means that the better the quality, if you take care of your car, then you are right to go up the price, but to the high price, His expenses are high, the cost is high, and the cost of using the car is also high, so this is decided according to your personal will, and at the same time, it must be taken into account.

Taking into account many other factors, in the end, 95 gasoline may not necessarily save money over 92 gasoline in terms of fuel economy.

No. 92 oil is cheaper than No. 95 gasoline, and the liters of No. 92 gasoline at the same price will be more than No. 95 gasoline, and in terms of driving distance, the distance traveled with No. 92 gasoline will be longer.

In the case of the same quality of gasoline, the engine compression ratio of the vehicle itself should also be considered from the perspective of driving distance. Automotive engines with high compression ratios can use fuels with better knock resistance, enabling higher energy conversion.

The difference between 92 gasoline and 95 gasoline.

The number of gasoline No. 95 depends on the octane number.

For example, No. 92 gasoline means that its research octane number is not less than 92The engine chooses a different oil grade, mainly depending on whether the compression ratio matches the octane number of the gasoline.

No. 95 and No. 98 unleaded gasoline refer to the fact that they each contain % of the "isooctane" with strong resistance to storming.

The quality of No. 95 oil is better than No. 92 oil. But in fact, the higher the grade of gasoline, the higher the quality, the better, and the quality of each grade of oil is qualified. The different labels are to distinguish the mid-octane number of the oil, and the oil with a high mid-octane number has a higher anti-knock performance.

In the case of good anti-knock effect, the faster the engine starts, and the easier it is to increase speed. However, the higher the grade of gasoline, the better the combustion stability will be, and the engine will not work abnormally due to deflagration. This is why engines running on 95 gasoline should never be filled with 92 gasoline, as there is a risk of damage to the engine.

But there is certainly nothing wrong with the engine marked with 92 gasoline plus 95. In terms of fuel saving, if the car marked with 92 plus 95 gasoline does have a little advantage in terms of power fuel consumption, but the advantage is not obvious, the so-called advantage in power is basically a psychological effect, as for fuel consumption, many netizens have also tested, adding 95 oil is indeed a little bit better than adding 92 oil, in other words, the use of 95 gasoline is indeed better than using 92 gasoline to save some fuel, but the fuel saving is not large, 100 kilometers of fuel consumption is about 2 3% lower, because of the 95 gasoline ** It is 6 7% more expensive than 92 gasoline, so although adding 95 is more fuel-efficient than adding 92, saving fuel does not mean saving money! In the end, when it comes to how much it costs per kilometer, it will cost more to use 95 gasoline.

It should be added according to the requirements of the model, and do not blindly pursue high-grade oil.

There is not much difference between 95 gasoline and 92 gasoline, so it is not necessarily good that 95 gasoline is good. The main difference is the difference in octane number. No. 92 gasoline is rich in 92% isooctane and 8% n-heptane; No. 95 gasoline is rich in 95% of isooctane and 5% of n-heptane, and the octane number of 95 is higher than 92, and the anti-knocking performance is better.

Generally, engines with high compression ratios use high-grade gasoline, and low-grade gasoline is used for low compression ratios. The higher the compression ratio, the higher the power of the car, the worse the stability performance, and the better knock resistance is required.

95 and 92 gasoline are not recommended to be blended.

The short-term mixing of 95 and 92 gasoline will not cause major damage to the car, but mixing gasoline with different labels for a long time will affect the life of the gasoline ignition system, fuel injector and spark plug.

It is better to add 92 oil or 95, depending on which grade of oil your car needs to use, requiring 95 plus 92 is easy to have problems, requiring 92 can add 95, that is, spending more money.

It depends on what kind of car, how big the displacement, etc., it is not a very good car, and it is not good to add 95 oil.

95 oil is a little better. Different gasoline contains isooctane and n-heptane, if the octane number of iso-octane is 100, then the octane number of n-heptane is 0. The proportion of isooctane in No. 92 gasoline is 92%, the proportion of n-heptane is 8%, and the proportion of No. 95 gasoline is 95% and 5%, respectively, and the higher the octane number, the less detonation the gasoline burns.

If it is a high-end car, add No. 95 gasoline, No. 95 gasoline is purer than No. 92 gasoline, and the quality is good, it must be the highest quality.

Gasoline is not necessarily better than 92, only by choosing the right gasoline can really play the role of the engine and not cause harm.

No. 92 oil and No. 95 oil will be better compared to No. 95 oil.

The difference between 92 gasoline and 95 gasoline is that they have different octane numbers, and 95 gasoline has a higher octane number. But this is not the main thing, the main difference between 92 gasoline and 95 gasoline is the difference in anti-knock performance, not the difference in octane number.

The gasoline manufacturing process in China is to catalyze the cracking of petroleum to obtain gasoline base oil. Then, in the later blending process, different amounts of antiknock agent are added to the base oil to obtain gasoline of different lease grades, such as No. 92 and No. 95 gasoline, and No. 95 gasoline has higher anti-knock performance; That is, there is no difference between 92 and 95 gasoline except for the content of antiknock agent. Because the same base oil is used, the octane number is the same.

Introduction to gasoline labeling

Gasoline is the label of gasoline, the octane number of gasoline is different for different grades, the higher the octane number of gasoline, the higher the octane number of gasoline, the better the stability of gasoline. Some cars need to run on 92 gasoline, and some cars need to run on 95 or 98 gasoline in order to prevent engine knocking.

Gasoline is labelled by comparison with a standard fuel that has been artificially blended, which has two components, isooctane with good knock resistance and n-heptane with poor knock resistance.

Gasoline is the blood that flows in a car and is the source of the car's power. For every friend who drives, gasoline is very familiar, but after using gasoline for so long, do you really know the difference between the 92 and 95 gasoline we usually use? Why do some cars add 92 and some add 95?

What is the significance of the No. 2 and No. 95 gasoline labels.

The gasoline label represents the anti-knock resistance, and the larger the mark, the better the anti-riot ability, which has nothing to do with the quality of the gasoline itself, nor does it mean that the higher the mark, the less impurities there will be.

The spark plug ignites the mixture, and the energy is released to drive the piston to move and do work.

To put it simply, the detonation is caused by the abnormal combustion inside the engine, because the spontaneous combustion of a part of the mixture inside and the ignition ignite the gas form an energy impact, resulting in the phenomenon of knocking the cylinder, and the detonation brings the loss of power.

The anti-riot substance is the isooctane in gasoline, the higher the label, the higher the isooctane content, and of course, the stronger the anti-knock performance.

Will the number 95 give the car better power than the number 92?

Some drivers will feel that the power of the car with 95 gasoline will be better, in fact, this is just a psychological effect, each car factory manual has recommended the use of 92 or 95 gasoline, according to this there is no problem, because what gasoline a car uses is related to the matching of the engine system, in essence, it is related to the compression ratio of the engine, the higher the compression ratio, the greater the power, the higher the efficiency, but the stability is poor, so the need for gasoline with high knock resistance. The compression ratio is not reached, and the use of higher gasoline will not help the power, at most it will be slightly better in terms of cleanliness and low carbon, but the effect is not very obvious.

There are often friends encountered, occasionally special circumstances out of oil, the two oils are mixed, generally there will be no big problems, but can not be used for a long time, which will cause detonation, lack of power, etc. The same car with a number 95 will not have a big problem occasionally using a number 92 gasoline, but if it is long-term, it will make the frequency of detonation more frequent and the wear and tear on the engine will be aggravated.

In the final analysis, the biggest difference between No. 95 and No. 92 is the difference in riot resistance, that is, the isooctane number contained is different.

It is better to choose the right gasoline for the car.

The number is just the label of gasoline and represents the octane number, which is the amount of isooctane. The octane number of No. 92 gasoline is 92, the isooctane content is 92%, and the n-heptane content is 8%. Similarly, 95 gasoline has an octane rating of 95.

The difference between reed and No. 95 oil in No. 92 oil

1. Composition of the difference between selling and searching belts. Gasoline 92 is made up of 92% isooctane and 8% n-heptane, while gasoline 95 is made up of 95% isooctane and 5% n-heptane. The two are mainly reflected in the purity of isooctane, the higher the purity of isooctane, the stronger the anti-knock resistance of gasoline, and the higher the relative cost.

2. Stability difference. No. 95 gasoline is particularly stable, and No. 95 gasoline is easier to burn, No. 92 gasoline has an octane number of 92 percent, and No. 95 gasoline has an octane number of 95 percent, and No. 95 gasoline is particularly easy to burn, so it is right to say that it is more resistant to burning. The two oils cannot be mixed and matched, and the gasoline mixture will lead to a bad engine, which will also have a particularly large impact on the life of the engine.

3. Differences in applicable models. When choosing 92 and 95 gasoline, please add it according to the car instructions, 92 gasoline is enough for general cars, and 95 gasoline for more expensive cars can meet the needs of the engine.

Gasoline, as a fuel, is one of the must-haves for vehicles. However, when choosing gasoline, many people will encounter a question, is it better to choose 92 or 95 gasoline? On this issue, we need to take a closer look at the difference between these two types of gasoline.

No. 92 gasoline is a more common gasoline with a lower RON (octane number) and MON (combustion value). As a result, it burns slower and produces less heat, which can make it feel underpowered at high speeds. However, because 92 gasoline is affordable,** it is cheaper than 95 gasoline, so in some areas with lower economic levels, 92 gasoline is still a good choice.

95 gasoline has a much higher RON and MON value compared to 92 gasoline. As a result, the amount of heat generated during combustion is also higher, and a car running on 95 petrol should feel a noticeable acceleration effect at high speeds. However, No. 95 gasoline will also be much higher than No. 92 gasoline gasoline**, and if it is a long-distance drive, the difference per litre will become very considerable.

To sum up, the choice of 92 gasoline or 95 gasoline depends on the ** of the two and the personal car needs. If you are driving for a short distance in the city or if the vehicle is less economical, you can choose 92 gasoline. On the other hand, if you need to drive at high speeds or increase power, you need to choose 95 gasoline.

In short, any slippery gasoline has its applicable situation, and consumers should make decisions based on their actual needs when choosing.
