The car has been using 95 gasoline, and the gas station mistakenly adds 92 gasoline, does it have an

This needs to determine what fuel you should add to your car, and generally the fuel tank cap will be marked on it:

1.**Note: No. 92 and above unleaded gasoline, No. 92 is the recommended oil;

2.**Note 95 98 unleaded petrol. If it is the first case, the car was originally added with 92 gasoline, but I have been adding 95 oil, and now I have added 92 oil, which basically has no effect on the car engine;

If it is the second case, the car should have been added with 95 oil, but the gas station has added 92 oil, and the car will show that there will be detonation during driving, the car shakes badly, and the driving is weak, the engine cylinder temperature rises sharply, the gasoline combustion is incomplete, the output power decreases, and the machinery is damaged. If the second situation is found in time after refueling, and the vehicle is not started, as long as you contact the repair shop to tow it away, release the fuel in the tank, and then add No. 95 oil to clean, and there is no harm to the engine;

If the second situation is found in the middle of driving after the vehicle is started, you should immediately contact the repair shop and tow the vehicle to the repair shop for repair, which will cause greater damage to the engine and damage the engine in serious cases. Finally, I would like to mention that some people think that 95 gasoline is more than 92 gasoline burned, but in fact, it has nothing to do with burning, but the octane number is different and the knock resistance is different. It is recommended that the vehicle factory is recommended to add what oil to add, low-grade oil vehicles to add high-grade oil, occasionally add little impact on the engine, but long-term addition, due to incomplete combustion, there is also harm to engine performance;

In fact, to put it bluntly, 92 95 is the octane number content in gasoline is different, but occasionally a mistake will not affect too much, the next time you add 95, if you add a certain type of gasoline for a long time, the driving computer will control the throttle opening, fuel injection and other data according to the oil product, and often change the gasoline model, which will cause poor power and insufficient combustion.

But don't mix gasoline and diesel... After all, adding the wrong 92 or 95 is gasoline, and the composition is the same, so it has little impact. But if it's diesel, then wait... Let's change the car...

Thank you. The difference between the two gasolines of No. 92 and No. 95 is that the octane number and combustion rate are not the same.

Occasionally, a mis-additive application has little effect on the engine.

Each car has its own suitable petrol to match the best operation of the engine, and the right one is the best. It should be visible on the inside of the fuel cap.

High-grade gasoline is used for engines with high compression ratios, and low-grade gasoline is used for engines with low compression ratios, because parameters such as ignition advance angles are set in the engine computer, as long as gasoline is selected according to the requirements, there is absolutely no problem.

I'm Chacha, if you have a problem with buying a car and repairing a car, please follow @Chacha Car.

This is a no-no! Originally, the engine was designed with a high compression ratio, and only 95 gasoline could be used to balance the deflagration! 92 Gasoline is not suitable for engines with this compression ratio.

It is okay to add 98 by mistake, and the oil label for gasoline engine can be high and not low! The theoretical design is determined by nature.

If your car manufacturer directs you to add 92, and you keep adding 95, and the gasker adds 92 to you, you will at least sue the gas station for bankruptcy, because your engine may be scrapped ten or eight years in advance

What does it matter once in a while?

If you are really worried that the 95 that is being used is out of gas, and the current gas station does not have 95, navigate to the nearest gas station, see the distance to decide how much 92 to add, and drive over to continue to add 95.

Even if it's 95 (used all the time), then 92 (n times), and then 95 again, it's fine.

The best way to do it: follow the manufacturer's instructions for using fuel, they're the experts!

Hello friend is absolutely no problem, don't worry! I hope my answers will help you, and if you have any questions, you can always contact me. BBA Mercedes-Benz BMW Audi Maintenance wishes you a happy life, all the best, and a lot of money!

It doesn't matter, adding the number 92 a few times once in a while has no effect, so feel free to use it. It won't have any impact at all.

Hello! It is recommended to change the petrol. For the engine of your car, replace it as soon as possible, release the old oil, clean the fuel tank, prevent damage to the fuel pump and fuel injector, and then fill with new fuel!

No. 92 and No. 95 gasoline can't be mixed! The 92 car that should use the 95 car is definitely not good, because it is easy to cause problems such as engine shock, detonation and insufficient power.

And there is no need to use a 95 for a car that is supposed to run on 92 gasoline, because as long as the engine does not knock, a higher fuel octane rating will not make the engine more powerful or more fuel-efficient, it will only cost you more money.

The so-called compression ratio is the ratio of the maximum stroke volume of the piston in the cylinder to the minimum stroke volume. Cars with a compression ratio between to generally use 92 gasoline; For cars with a compression ratio greater than 95 gasoline, 95 gasoline should be used. Generally, the compression ratio of high automobile engine, high power, high fuel efficiency, but often low stability, so the need for better anti-knock gasoline, 95 gasoline compared with 92 gasoline advantage is that its octane number in the gasoline proportion is high, fuel anti-knock is good.

If your car has been using 95 gasoline, and the gas station staff mistakenly added 95 gasoline to 92 gasoline, it will not hurt the car engine in this case, because the quality of 95 gasoline and 92 gasoline is about the same, and the occasional use of 92 gasoline will not cause too much damage to the engine, but it will have a certain impact on the power of the car.

First, this situation will not hurt the engine.

The car has been using 95 gasoline, and the staff at the gas station added the wrong oil, and used 92 gasoline, for this situation is not to harm the engine, after all, the engine is not as fragile as you think, because it is just a mistake to add the wrong oil, not long-term use of 92 gasoline, if the owner of the car uses 92 gasoline for a long time, and the car stipulates that 95 gasoline should be used, then the damage to the car is very high, generally speaking, the use of 92 gasoline is a high compression ratio engine, This engine is particularly good for shock resistance, so there is no problem at all with this engine using 92 gasoline. <>

Second, this situation will affect the power of the car.

You must know that there is still a certain gap between the quality of No. 95 gasoline and No. 92 gasoline, but the purity of No. 95 gasoline is higher, so the performance is better when using a low compression ratio engine, and the power can be stronger. When the car that uses 95 gasoline for a long time adds 92 gasoline, the engine power will be weakened in this case, but it does not affect the service life of the engine, as long as the owner uses up the tank of gasoline, you can add 95 gasoline. <>

3. Summary. Generally speaking, if the car that uses 95 gasoline for a long time, if the gas station mistakenly adds 92 gasoline, it will not hurt the car engine in this case, because it is not used for a long time once in a while, and the damage to the engine is almost none, but this will affect the power of the engine, so the owner should not worry too much. <>

It will hurt the engine, because the molecules of the two oils are not the same, if you add 92 gasoline, the power of the car will decrease, and the gasoline will not be fully burned.

If this is the first time that 92 oil is added, it will not hurt the engine, because the impact this time will not be particularly large, as long as 95 gasoline is used next time.

I don't think it will have much of an impact, but don't make a mistake too often, as this will lead to carbon deposits and oil blockages.

Some people say: The oil cap is not already marked with the model and specification of the filling, why do the workers still need to ask? Since there are many car buyers who will prescribe the filling of higher grades of gasoline.

In order to work better and more carefully and meticulously, the staff of the gas station will understand again before refueling.

Many people say that the higher the model of gasoline, the better the quality, so the buyers who add 92 gasoline will choose No. 95, and those who originally added No. 95 will choose No. 98. In fact, the model does not represent the quality of gasoline, but only its anti-knock performance. The higher the model, the better its explosion-proof type, when the mixture inside the gasoline and diesel engine is reduced, if the shrinkage is higher, when the ignition is not started, the gasoline will be ignited early, which will cause the vibration of the main cylinder.

Gasoline with a relatively high corresponder is not easy to cause this situation!

The biggest difference between No. 92 and No. 95 is that the octane number of gasoline is different, if the gasoline filled does not meet the specifications of the automobile engine, resulting in engine knocking, the noise of the automobile engine will be very large, and it will continue to cause fluttering, and the driving force will be lacking. The octane number of No. 92 gasoline is 92%, and the composition of No. 95 is 95%, which means that the higher the model, the higher the octane number of gasoline, and the better the anti-knock performance. If your car is filled with 95 gasoline, you don't have to add 92 gasoline because it is cost-effective, otherwise it will cause the car engine to be destroyed and cause great damage.

Generally, Japanese cars or low-end cars, you can fill 92 gasoline, if you buy a new car, and you don't know how to give oil, you can open the oil cap, and the model number of the filling is written on it. This designation refers to the minimum level of gasoline to be filled. The 92 oil to the 95 will be more reliable, and the noise will be reduced, and most importantly, the driving force will be further improved, and the turbocharger car engine will mainly perform more significantly.

No. 92 oil can be filled with higher gasoline models, if you have sufficient assets, there is no problem with adding No. 98, but it is not necessary at all, just add 95.

I believe that we have all seen a proper noun called the engine compression ratio of automobile engine, which is used to indicate the level of gas mixture reduction, and manufacturers will strongly recommend the corresponding gasoline model to customers according to the engine compression ratio when manufacturing cars. For example, the proportion of this ** car is reduced to the middle, so you can choose No. 92. If it is between 10 and middle, you can raise 95.

If the proportion is exceeded, it is necessary to add 98. Be sure to choose the gasoline marked on the oil cap or a higher type of gasoline when you are working hard, otherwise it will cause an engine knock.

One thing I have to remind everyone is that if you want to fill up with a higher type of oil, you must make sure that the oil inside the car is almost gone. Then go and fill a higher type of gasoline, otherwise you will mix these two different types of gasoline, although it is not very harmful, but it is still to be prevented. For example, Sinopec or PetroChina, if you want to change to a different oil manufacturer, you need to use up the previous oil.

Although the quality of gasoline is basically the same, there are certain differences in key points.

The damage will be, the carbon deposit increases the fuel consumption and increases the power of the car obviously feels the decline, if you add it once, it's okay, you can't add it all the time, the first number of gasoline is only added in the case that there is really no way, it is not usually recommended.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Questions. The number of gasoline is added once.

Questions. If you have been using 92 gasoline to add 95 once, will it be harmful to the car if you change it back to 92?

If it doesn't affect me in any way, feel free to use it.

Questions. I want to change to 92 petrol now, does it affect the car?

There is no impact, there will be carbon deposits in the cylinder as long as the engine is working, this is all the rhetoric of the 4S shop, don't care.

Nothing, nothing.

It is damaged, the fuel tank must be cleaned, this phenomenon will lead to a situation of car failure, which will affect the service life of the engine.

This situation may be damaging to the car, so it is best not to change the model of gasoline abruptly, which is not conducive to the life of the vehicle.

It will have a serious impact on the engine of the car, and there is no way to better repair the car, and there will be many problems in the later stage of the car, and it is easy to scrap.
