What is the difference between 92 and 95 gasoline? Which is better in comparison?

Different labels, in fact, many owners in China have some misunderstandings about their perceptions. The main component of gasoline is isooctane, and the essential difference between No. 95 and No. 92 gasoline is that the isooctane content of the two is different, the isooctane content of No. 92 gasoline is 92%, and the isooctane content of No. 95 gasoline is 95%. The higher the isooctane content, the higher the purity of the gasoline, and the better the knock resistance of the gasoline, which means that the combustion of No. 95 gasoline is more likely to be precisely controlled.

Just like horses with a purer pedigree are more docile and easier to train.

The octane number is affected, which is the resistance of gasoline when the engine burns. When gasoline combustion occurs, the flame propagation speed is 100 times lower than normal, and not only the temperature of the engine block is 100 times lower. Boost, it will also be significantly energized.

The efficiency of the engine is not said and is usually damaged. For engines with high compression ratios, it is necessary to use high-aisle gasoline, the car manufacturer will provide clear tips, follow the requirements, some cars need to use 95 gasoline to reduce engine knocks, but the owner has to add a relatively cheap 92 gasoline in order to save food costs, but do not know that it will be a great injury to the car engine. Some owners are the exact opposite.

Generally speaking, the compression ratio of cars using 95 gasoline is larger, such as the classic Volkswagen EA888 engine. The compression ratio of the engine using 92 gasoline is in between, but Mazda's engine is accidental, although it has a compression ratio of 13:1, it can still use 92 gasoline.

However, whether it is added to 92 gasoline or 95 gasoline, it does not show the quality of the engine, on the contrary, the engine that can achieve a high compression ratio and can use low-grade gasoline at the same time is a really powerful engine. When we use the car, we can fill the corresponding gasoline according to the manufacturer's instructions, often mix gasoline, or often change the gasoline label, which has an impact on the fuel injection system of the vehicle and the service life of the spark plug.

The knock resistance and burn resistance of No. 92 gasoline and No. 95 gasoline are not the same, and the chemical composition of No. 95 gasoline will be more complex than that of No. 92 gasoline. In comparison, 95 gasoline will have better knock resistance and burn resistance, but ** will also be higher.

No. 92 gasoline is a bit more expensive than No. 95 and is purer in composition. The octane content of gasoline 95 is a little higher than that of gasoline 92, which is 92% octane and 95% octane in 95 gasoline. As for which oil is better, this should be based on the car maintenance manual to know which gasoline should be added, either expensive or suitable, because the car factory is identified by the relevant national agencies.

No. 95 gasoline has a higher isooctane content, so the purity of gasoline is high and the knock resistance is good. But not every car uses gasoline of this marking. The factory instructions for each car have a recommendation for which type of gasoline to use.

The car should have used high-grade oil, but adding low-grade oil has certain damage to the car; On the contrary, there is really no big doubt, it is just that the cost is high.

First of all, it should be said that there is no direct relationship between the marking and the quality of gasoline. The anti-explosion performance of the brand represents the anti-explosion performance of the gasoline, and the anti-explosion performance is generally speaking, the anti-vibration ability of the car in the process of movement is better, but this does not mean that the higher the grade of gasoline, the better it is, and it is the right choice to choose the appropriate gasoline that matches the engine of your car. Therefore, when you refuel, you can choose according to the instructions of the manual or follow the advice of the gas station staff.

Nowadays, most of the engine programs of automobiles will be set up with an adjustment function for anti-explosion performance, especially for low-grade gasoline with poor anti-knock performance, while high-grade gasoline does not have this setting. So if we add too much gasoline, it will cause poor acceleration during driving, and there is no way to make this function work, except for waste.

However, if you use gasoline with a lower grade than your own suitable grade, it may also cause hindrance to the engine start, and it will also cause some damage to the engine. Therefore, it is necessary to choose gasoline that matches the number of your car, as well as gasoline with good oil quality, so that it is beneficial to your car.

In fact, the main difference between the two is the difference in the proportion of chemicals they contain. On the one hand, the proportion of n-heptane in No. 92 gasoline is slightly higher than that in No. 95 gasoline, and the proportion of isooctane in the former is slightly lower, and the anti-knock is weaker than that of the latter. On the other hand, the different labels of gasoline also mean that the octane number of gasoline is different, generally speaking, the larger the label, the higher the octane number of gasoline.

Of course, which gasoline to choose has nothing to do with the price, it mainly depends on the engine model of the car.

In daily life, when we refuel, we may occasionally fill in the wrong gasoline, and there may still be residue in the engine. If the two gasolines are mixed together, it will cause some damage to the engine, and even in severe cases, it may cause a cylinder burst. But don't worry too much, once or twice won't have much impact on the engine.

If you fill up the wrong gasoline more often, you need to call in a professional to clean it up to prevent dangerous incidents.

The biggest difference between these two types of gasoline is that n-heptane and isooctane are not the same.

Among them, No. 92 gasoline is rich in 92% isooctane and 8% n-heptane; Whereas 95 gasoline is rich in 95% isooctane and 5% n-heptane.

In addition, the gasoline mark also represents the anti-knock resistance of the fuel, and the larger the mark, the better the anti-knock performance. It is worth mentioning that the gasoline label has nothing to do with the quality of the gasoline itself, and it does not mean that the higher the gasoline, the better, or that the higher the gasoline does not mean that there are fewer impurities or the purer the purity.

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.

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.

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.

No. 95 gasoline and No. 92 gasoline, what is the difference between the two, can you add them at will.

The answer is yes, add 95 gasoline, the power will be better than 92!

The power experience of high-grade gasoline is better, mainly because of the difference in anti-knock performance of high-grade and high-grade gasoline.

The anti-knock performance of No. 95 gasoline is stronger than that of No. 92, and the stronger the anti-knock performance, the greater the ignition advance angle of the engine, and the better the power it shows.

With the same amount of throttle pedaling, the No. 95 gasoline will perform more effectively than the No. 92.

If you are accustomed to the strength of No. 95 gasoline, after changing to No. 92 gasoline, drivers usually can't help but step on the accelerator deeply, which is why many drivers feel that fuel consumption has increased after changing to low-grade gasoline.

For cars with turbocharged and high-compression ratio engines, the power will drop significantly with low-grade gasoline, and the likelihood of knocking will be higher.

If you want to have better power when running long distances and high speeds, you should choose 95 gasoline.

For those cars with naturally aspirated engines and compression ratios below the limit, adding 92 is sufficient.

Comparing ** and quality, high-quality No. 95 gasoline and cheap No. 92 gasoline, which one is better?

Hello, 95 good, less oil magazine, burn resistant.

95 is good, but it doesn't necessarily apply to our car. Choosing the right oil is the last word.

It's not a question of which one is good, it's a question of which oil is suitable for your car.

Hello, 95 will be better, the purity is relatively high.

What is the difference between 92 and 95 gasoline? I'm glad I didn't make a mistake.

The difference between No. 92 gasoline and No. 95 gasoline is that the concentration of No. 95 gasoline is purer than that of No. 92, and it is necessary to choose according to the price of the car.

No. 92 gasoline has a national standard, that is to say, the country has mandatory standards, and No. 95 gasoline only stipulates the octane number, that is to say, No. 92 gasoline is the base gasoline, and some additives are added to increase the octane number of gasoline.

For example, add some seasoning to a bowl of clear soup. Therefore, if you can fill a car with 92 gasoline, don't add 95 gasoline, because 92 gasoline is cleaner.

The applicable compression ratio is different, the car with the compression ratio between the 92 gasoline should generally use 92 gasoline, and the car with the compression ratio greater than 95 gasoline should use 95 gasoline; The octane number of No. 93 gasoline is lower than that of No. 95 gasoline, that is, No. 92 gasoline contains 92% of isooctane, while No. 95 gasoline has an octane number of 95%.

What is the difference between 92 gasoline and 95 gasoline? Which gasoline is more powerful?

Compared with No. 92 and No. 95, No. 95 gasoline is a little purer and more powerful. Therefore, the quality of No. 95 gasoline will be higher, and of course, ** will be higher.

The difference between No. 92 gasoline and No. 95 gasoline is that the isooctane content is different, No. 95 gasoline has an iso-octane content of 95%, and No. 92 gasoline is only 92%, so No. 95 gasoline is of higher quality.

Here is only about the use (test) under the same conditions, the same car with the same road conditions and the same route, from Beijing to Luzhou is about 2000 kilometers, 1 round-trip driving, plus 95 gasoline than 92 gasoline, saving 700 yuan. Note: The model used is the 2003 Fengshen Bluebird 2nd generation, displacement, and has been tried repeatedly.

Later, after changing cars, it was never counted again.

First of all, we must know that the numbers of gasoline 92 and 95 represent the octane number of gasoline, that is, the anti-knock of gasoline, the higher the octane number, the better the anti-knock performance, and relatively speaking, the better the anti-knock performance of high-grade gasoline.

Secondly, the question of which gasoline is better to use should be determined on a case-by-case basis. The factory instructions for each car have a recommendation on which type of gasoline to use, because the type of gasoline used in a car is related to the compression ratio of the engine. If the compression ratio is higher, the power is higher, the efficiency is higher, but the stability is poor, and gasoline with high knock resistance is required.

And if the compression ratio is not reached, using 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.

The number of gasoline added is not determined according to whether it is turbocharged or not, but according to the number of gasoline designed by the engine at the beginning of the design according to how many numbers of gasoline to determine how many numbers are added, and the best way is to look at the instructions to ask for how many numbers to add.

Choose the oil number according to the label on the fuel tank cap, 95 has a higher octane number than 92, and the anti-storm performance is better, but if a tank of oil is calculated according to 50 liters, 92 will be cheaper than 95 thirty or forty yuan. The higher the value, the more fully the oil burns in the engine, and the power is also improved. It should be noted that if you add 92 oil first, you can directly add 95 or higher value of oil, but after adding high value of oil, you cannot directly add low value oil when the remaining oil in the fuel tank is sufficient, otherwise it may hurt the engine and aggravate engine shaking.

Therefore, according to the label on the fuel tank cap, as well as their own needs and their own economic strength, choose the fuel number they want to add under the condition of ensuring the safety of the vehicle.

What size of gas does the car have? Each car type will have clear instructions, and if your car requires a 95 petrol fill, it is recommended not to use a 92 petrol.

The difference between No. 95 gasoline and No. 92 gasoline is the difference in octane number, that is, the difference in anti-flash burning. The anti-riot performance of No. 95 is better than that of No. 92, so it is recommended to use No. 95 gasoline for cars with high compression ratio engines, if No. 92 gasoline is used, it is easy to produce engine knocking, and long-term use may damage the engine.

If your car is recommended to use 92 gasoline, there is no need to use 95 gasoline, except for spending more money, it will not have much impact.

You can't blindly use high-grade gasoline.

Nowadays, many people are keen to use high-grade gasoline, and even regard the label as a standard of fuel purity and quality. In fact, the gasoline label only indicates the octane number of gasoline, that is, the knock resistance, and has nothing to do with purity and quality. If the engine set to No. 92 oil is hard to use No. 95 oil, there will be a phenomenon of "stagnant combustion", that is, it is not yet the spontaneous ignition point when it is pressed to the end, and the combustion is not complete, which will cause pollution and waste.

Extended Data Hazards.

If a low-grade car uses high-grade gasoline for a long time, in addition to knocking, it will also cause problems such as power drop, fuel consumption increase, and damage to engine internal parts, which will seriously shorten the life of the engine. It can be seen that the higher the gasoline grade, the better, even if it is a high-end car, it does not mean that you must add high standard oil, and the suitable one is the best. Therefore, before refueling your car, you must carefully read the manufacturer's instructions and choose gasoline according to the instructions in the manual.

Different engines have different compression ratios, which also determines the most suitable oil number.

If a car with a low compression ratio adds high-grade gasoline, it will waste fuel costs, and it will also cause the car to have "symptoms" such as slow engine ignition, easy exhaust valve burnout, and weak acceleration.
