Can I add 95 back to 92?

OK. It does not have much adverse effect on the car and the engine itself, but because the design compression ratio is not high enough, it cannot make full use of the characteristics of 95 gasoline, and there will be a "stagnant burning" phenomenon and increased fuel consumption.

Select the gasoline designation according to the vehicle type:

Gasoline is suitable for ordinary cars with low technical content.

For models with less than 100,000 yuan on the market, No. 92 gasoline is their best partner, which is suitable for those models with mature engine technology and no excessive requirements for fuel. However, the choice of which gasoline label is not blindly divided by the price of the model.

Gasoline is suitable for the vast majority of cars.

95 petrol is generally suitable for turbocharged and high compression models, and it is compatible with most vehicles.

If you usually add 95 gasoline to the car and want to add it back to 92, then make sure that the vehicle can be filled with 92 oil, otherwise there may be insufficient power, engine failure lights on, abnormal fuel consumption, etc.

No. 92 and No. 95, there is no one type of mark that is good for the engine, only the engine is most suitable for a certain grade.

Difference Between 92 Gasoline and 95 Gasoline.

1. Different octane numbers: No. 92 gasoline is rich in 92% isooctane and 8% n-heptane; Whereas 95 gasoline is rich in 95% isooctane and 5% n-heptane.

2. Different power and fuel consumption performance: No. 95 gasoline has more advantages than No. 92 gasoline in terms of power fuel consumption, because its isooctane content is higher than that of No. 92 gasoline.

3. Different: 92 gasoline is cheaper than 95 gasoline, due to market competition and regional factors, the oil price of each gas station is not the same, for example, the gas station near the city center is better because of the location, and there are more people refueling, generally ** will be a little higher, and in the suburbs and other remote gas stations, the overall oil price will be lower. But no matter how it changes, at the same gas station, 92 gasoline is cheaper than 95 gasoline.

After the car is added to No. 95 oil, it can be added back to No. 92 Normally, the type of gasoline that should be used in the car will be stated on the oil cap of the car, and gasoline has two important components, one is n-heptane and the other is isooctane. No. 92 is 92% isooctane and 8% n-heptane. But adding 95 gasoline will be better, and it is good for the car.

The higher the fuel grade, the slower the combustion rate of the oil and the lower the combustion knocking, on the contrary, the combustion speed of the low-grade fuel is faster and the combustion knocking is larger.

Hello, nice to serve you, can. In fact, this is determined according to the label specified by the manufacturer, as long as the 92 gasoline is within the range of the gasoline label specified by the manufacturer, then there is no problem with adding 95 gasoline and adding 92. Some models are required to use 95 gasoline, so it is not recommended to change to 92 gasoline, because the fuel label is too low, there may be deflagration and detonation, and the power will be reduced.

If you accidentally add 92 gasoline, it will not be a big problem, but if it continues in the long run, it may not burn normally, resulting in a large amount of carbon deposits, which will adhere to the top of the piston, the valve, and the fuel injector and spark plug, which will also affect the life of the gasoline pump and fuel injector.

Precautions: Refueling can not be too full, 2 3 position can be, because refueling is too full, the car will vibrate violently during the driving process, and some gasoline will overflow, which is very dangerous. At the same time, spilled gasoline can also corrode the paint near the tank.

In the process of refueling, resolutely avoid open flames: we all know that gasoline is volatile and flammable, and it is very easy to encounter an open flame, so in the process of refueling, remember not to smoke and use open flames.

Yes, it's just that the higher the sign, the less impurities it contains, so it's no problem for you to add back to the original 92.

Ordinary vehicles are perfectly fine. If the vehicle is filled with 95 gasoline, it can be refilled back to 92 gasoline. There is a difference in the anti-knock performance of No. 92 and No. 95 gasoline.

No. 95 gasoline is suitable for the case of high engine compression ratio, if the compression ratio is high and No. 92 gasoline is used, abnormal combustion will occur, and it will detonate.

It's okay, it doesn't matter if you add 92+95 to the car first, you can clean the machine when you add 92.

No. 95 gasoline and No. 95 gasoline can be mixed, but the anti-knock performance of these two gasolines is different, that is, low-grade gasoline can be mixed with high-grade gasoline.

2. Cars that have been using No. 95 gasoline cannot be mixed with No. 92 gasoline, that is, high-grade gasoline cannot be mixed with low-grade gasoline, which may cause insufficient vehicle power.

3. The larger the number of gasoline, the higher its isooctane number, and the higher the proportion of isooctane, the better the anti-deflagration performance of gasoline, which has a relatively large restraining effect on the formation of carbon deposits after combustion. When gasoline is compressed in the combustion chamber of the engine, if the anti-knock performance is poor, it will be ignited in advance, and then detonation will occur, and such a thing will not happen to gasoline with good anti-knock performance. The higher the compression ratio of the engine, the higher the requirements for the anti-knock performance of gasoline.

Mixing in a short period of time will not cause much damage to the car, but mixing gasoline of different grades for a long time will affect the life of the ignition system, fuel injector and spark plug of the car.

Before each car leaves the factory, the manufacturer will carefully evaluate how much oil is suitable for the engine of their vehicle, in fact, it is generally in accordance with the guidance standards stipulated by the vehicle to refuel the car. Therefore, there is no saying that the higher the grade, the better the engine, at most it increases the anti-knock resistance.

The advantage of No. 95 gasoline over No. 92 gasoline is better anti-knock performance, it does not improve the power performance, it will be slightly better in terms of cleanliness and low carbon at most, but the effect is not very obvious.

If you need to add 95 to the car with 92 gasoline, then it is easy to detonate, lack of power, for a long time will cause damage to the engine, but also cause carbon deposits, but once or twice will not cause any effect. The car that needs to be added to 92 has 95 gasoline, there will be no change in power, and it will not be cheaper, so it is recommended to refuel according to the factory manual.

If you recommend using No. 95 gasoline and mix it with No. 92 gasoline, it may affect the engine, and it will not be too much of a problem not to drive aggressively in this case. Of course, the vast majority of car companies have set the ECU after the new car leaves the factory, and the deflagration situation is also controlled to a certain extent.

So if you find that there is nothing abnormal in the car driving, then you can add it back to No. 95 after the fuel is used up. If you find that there is a deflagration phenomenon, if you are not at ease, buy a bottle of octane number additives, which is mainly to increase the octane number of fuel to increase the anti-knock performance. If you are still not sure, pump out the current tank and refill the 95 gasoline.

Pay attention to gasoline labeling: It should be noted that gasoline marking refers to the ratio of actual gasoline anti-knock resistance to standard gasoline. The higher the grade, the stronger the anti-explosion performance. Models with high engine compression ratios need to be fueled with high-standard gasoline.

Car owners still need to follow the instructions on the car or the logo on the fuel tank cap to properly fill the gasoline. Due to the compression ratio, high-standard gasoline cars need gasoline with better anti-knock performance, and the use of low-standard gasoline will cause knocking in the engine cylinder. Even if a car with low-standard gasoline is added with high-standard gasoline, there will be no knocking, but there will be excessive carbon deposition due to insufficient temperature and pressure in the cylinder.

No. 92 oil is not used up, and No. 95 can not be added. Gasoline is a mixture, and the gasoline label that we usually come into contact with refers to the difference in the anti-knock index (i.e., octane number) of gasoline.

The biggest difference between No. 92 gasoline and No. 95 gasoline is that the octane number in gasoline is different, and the higher the octane number, the stronger the violence resistance of gasoline, the general automobile engine has a specified compression ratio, through the compression ratio we can choose the corresponding gasoline model, the compression ratio is 8-10 to choose 92 gasoline, and above 10 is to use 95 gasoline.

If the engine with a high compression ratio uses 92 gasoline, it will cause the vehicle engine to detonate, resulting in unstable idling, decreased power, increased fuel consumption, and may also lead to engine valve bending, and even damage to the throttle chamber cover. Therefore, a car with No. 95 oil must not use No. 92 gasoline for a long time, unless the vehicle runs out of gas halfway.

The number of gasoline is determined by the octane number, the stronger the anti-knock of the high standard value of gasoline, and its combustion rate becomes slow, when the gasoline is not fully burned in the engine, there will be carbon deposition and insufficient power in the engine.

OK.

95 gasoline is not used up, you can add 92. Occasionally, once or twice the problem is not big, but long-term mixing will have a certain impact, if the long-term mixing is prone to the phenomenon of engine knocking, the engine will output weak power during driving, increase fuel consumption and other adverse effects. It will also have a certain impact on the ignition system, fuel injection system and engine life of the car.

Precautions for the use of engine oil.

Some riders will think that the more lubricating oil you add, the better, but this is not the case. The amount of lubricating oil in the car should be controlled between the upper and lower scales of the oil dipstick. Because if there is too much lubricating oil, it will enter the combustion chamber from the gap between the cylinder and the piston, and burn to form carbon deposits.

These deposits can increase the compression ratio of the engine and increase the tendency to detonation; The red-hot state of carbon deposits in the cylinder is also easy to cause premature ignition, such as falling into the cylinder will aggravate the wear of the cylinder and piston, and will also accelerate the pollution of lubricating oil. Secondly, too much lubricating oil increases the stirring resistance of the crankshaft connecting rod, which increases fuel consumption.

If you add 95, you can add 92 back, and normally on the oil cap of the car will indicate the type of gasoline that the car should use.

No. 92 gasoline is a gasoline with an octane rating of 92, which is suitable for mid-range cars (with a lower compression ratio).

The English name of gasoline is petrol (English), the appearance is a transparent liquid, flammable, the distillation range is 30 to 220, and the main components are C5 C12 aliphatic hydrocarbons and naphthenic hydrocarbons.

As well as a certain amount of aromatic hydrocarbons, gasoline has a high octane number (anti-knock combustion performance), and is divided into 90, 93, 95, 97 and other grades according to the octane number.

Gasoline is prepared by blending different gasoline components such as straight-run gasoline components, catalytic cracking gasoline components, and catalytic reforming gasoline components obtained from petroleum refining with high-octane number components.
