After using 95 gasoline for a while, can I add 92 gas? There is no impact on the car

OK. The higher the grade of gasoline, the stronger its anti-knock performance, which has nothing to do with the quality of the oil. Gasoline and air are mixed and compressed in the cylinder, and if the pressure is too high, deflagration will occur, making the engine unable to work normally. In fuel oil, the anti-riot substance is isooctane.

The higher the label, the higher the isooctane content and the stronger the knock resistance. So, whether you are 92 gasoline or 95 gasoline, they are only different in the amount of isooctane in gasoline, and there is no difference in the quality of gasoline, and the calorific value of fuel per unit volume.

Hello, there is no problem with this, you originally used 95 gasoline, and after you run out, you can directly add 92 gasoline, which has no effect on the engine.

Hello, this car recommends that you continue to use 95 oil, 92 oil does not burn enough and is not good for the engine.

Hello, this mainly depends on your car, the model, which one is added, the number of gasoline, the normal price is 95.

Tell you about this situation, this has no effect. As long as you don't mix it up too often. The gasoline for 92 must be used all the time.

Hello these two different gasoline 92 gasoline and 95 engine oil, just fine, do not mix.

Hello, this mainly depends on what kind of model, if you can add 92 gasoline from the factory, there is no problem with adding 92.

Hello, there are regulations on what kind of oil to add, and there is no problem with not very high-end cars, but it is not recommended to change the fuel label frequently.

As long as the gasoline is added according to the manufacturer's recommended number, it will be fine, and if the manufacturer recommends 92, you can add it, it doesn't matter.

You seem to be able to change this, depending on what model you are, for the standard 92 gasoline, it is not recommended that you use 95, you can always use 92 gasoline.

What kind of car does this look at, if you can add 92 gasoline on the manual, you can add it, refer to it.

It depends on what kind of model you have, some models can't use 92 gasoline, but most of them can.

Normally, it is not recommended to change the number of gasoline frequently, and it is enough to use one frequently, otherwise it will affect the life of the engine.

This needs to look at the number of the oil you add to this model, if you are required to add 95 gasoline, you can't add 92.

Hello, it is not recommended that you use fuel like this. Do not change the fuel model of the vehicle at will. This will affect the normal combustion of the engine.

This depends on the oil number marked on your car, if your car is marked with 92 oil, you can use 92, if it is 95, you can't use 92.

You can add it, you may feel poor power in the early stage, and nothing else will affect you.

This situation mainly depends on what brand of your car is and how many sizes of gasoline you need to add according to the requirements of the manual.

This question depends on yourself, what fuel is added in his instructions, and it is best not to replace it.

You need to see what kind of vehicle it is, and how much gasoline you want to add?

95 cars plus 92 gasoline has an impact

If the car is only occasionally filled with 92 gasoline, it will not have much impact, if 92 gasoline is added for a long time, it will cause certain damage to the engine of the car, and in serious cases, it may lead to the scrapping of the engine, and there is no value of brother hole maintenance at all. The reason why cars are marked with oil numbers is because the performance of the engines is different.

The higher the gasoline grade of the car, the better the anti-knock performance of the engine, if the fuel grade of the engine is 95, then the engine must be filled with 95 gasoline. If you use gasoline of different grades for a long time, it will affect the ignition system, fuel injector and spark plug life cycle of the car, and in severe cases, it may cause problems such as engine shake, valve bending, and valve cover damage.

The importance of gasoline

Refers to the ability of gasoline to resist knock combustion under various conditions of use. The knock resistance of motor gasoline is expressed by the octane number. The higher the octane number, the better the knock resistance.

The magnitude of gasoline's anti-knock ability is related to the chemical composition. Branched alkanes, olefins, and aromatics generally have excellent knock resistance. The octane number of isooctane is 100, and the knock resistance is good; The octane number of n-heptane dust is 0, and the anti-knock resistance is poor.

The octane number of gasoline is determined by the octane counting machine. High-octane gasoline can meet the needs of gasoline engines with high compression ratios. If the compression ratio of the gasoline engine is high, the thermal efficiency is high, and the trace mu can save fuel.

Increasing the octane number of gasoline is mainly achieved by increasing the composition of high-octane gasoline, but it is also achieved by adding antiknock agents such as MTBE. The grades of gasoline are classified by octane number.

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.

Summary. Hello, requiring 95 oil and using 92 all the time will lead to increased engine fuel consumption, lack of power, idle jitter and severe carbon deposits in the cylinder. The fuel grade used in the engine is too low, which will cause the engine to have a strong burst and cause the engine to delay the ignition time, and because the burst continues to increase, it will cause the ignition time to be very late, resulting in increased fuel consumption and insufficient power.

Strong vibrations can even damage the internal mechanical structure of the engine, causing the connecting rod to bend or be damaged, and in serious cases, the engine will be scrapped. The vehicle must use the gasoline specified by the manufacturer, and must use a bottle of fuel treasure every time it is maintained to remove the carbon deposits of the engine and fuel injectors, so that the engine is kept in good condition, which is helpful for reducing fuel consumption and noise.

The car asks for 95 gasoline, and what are the consequences of adding 92 gasoline all the time.

Hello, requiring the use of No. 95 oil and using 92 all the time will lead to an increase in fuel consumption, insufficient power, idle jitter and serious carbon deposition in the cylinder. The fuel grade used in the engine is too low, which will cause the engine to have a strong burst and cause the engine to delay the ignition time, due to the continuous increase of the burst, the ignition time will be very late before the leakage, resulting in increased fuel consumption and insufficient power. Strong vibrations can even damage the internal mechanical structure of the engine, causing the connecting rod to bend or be damaged, and in serious cases, the engine will be scrapped.

The vehicle must use gasoline specified by the manufacturer, and must use a bottle of fuel treasure at each maintenance time to remove the carbon deposits of the engine flush and fuel injector, so that the engine is kept in good condition, which is helpful for reducing fuel consumption and noise.

So how to deal with this situation now.

Or run out of 92 gasoline and add 95 gasoline directly.

Add a bottle of fuel treasure to the fuel tank, and replace it with a 95 one after the tank runs out.

Look at how much oil is still in the tank, and more than half of them can be added directly to 95. Or you can use a bottle of fuel additives.

Personally, I think if your car is filled with 95 gasoline for a long time, and the gas station mistakenly fills in 92 gasoline, will it affect your carIt still depends on the number of gasoline specified in your car's car manual.

According to your description, your car has been using 95 gasoline, and it is inferred that your car manual should be 95 gasoline, so the gas station mistakenly added 92 gasolineThis can adversely affect your car's engine.

Here's why:Because the fuel grade of the car with the gasoline engine we use is determined by the compression ignition deflagration resistance corresponding to the proportion of n-heptane contained in the gasoline, and the combustion chamber compression ratio of the gasoline engine. If the compression ratio of your car's gasoline engine is around the limit, and the instructions require you to add 95 gasoline, then you must choose 95 gasoline with a n-heptane content of less than 5%.

Otherwise, when you add No. 92 gasoline, the gasoline engine will produce high temperature in the compression stroke with a larger compression ratio, and the No. 92 gasoline contains more n-heptane, and its ignition point is under the compression high temperature, which will cause the mixed flammable gas to deflagrate before reaching the top dead center (in the compression stroke), (the normal situation should be that the piston should be ignited by the spark plug after reaching the top dead center) and at this time, the running direction of the piston is opposite to the running direction of the cylinder after deflagration, resulting in a knocking sound like knocking on the door. This deflagration generates the opposite force on the piston, which will cause external force damage to the transmission parts of the engine, such as pistons, piston rings, connecting rods, connecting rod pins, crankshafts, and bearings.

Once in a while, it can also cause damage to the engine. If you don't pay attention to this phenomenon of your car, it will cause organic damage to the engine in the long run, reduce the engine life, reduce the engine power, and in serious cases, it will lead to early overhaul of the engine.

Therefore, the car with the nominal addition of 95 gasoline must add 95 and above gasoline, and must not add 92 gasoline, you must not add it indiscriminately!
