Can 93 gasoline from different manufacturers be mixed?

Yes, it does not affect each other, the gasoline label refers to the anti-knock resistance, and there is no essential difference in additives The difference is that the comparative concentration of the two gasolines is different, and the mixing is like 90% and 75% pure alcohol blending The same can be burned and disinfected.

Gasoline can be blended. But it can only be mixed upwards, for example, it should be required to add 93 gasoline, but 97 can not add 93. The designations 90, 93, and 97 only represent their anti-knock resistance.

Hello, this should be fine, it is a universal oil label.

PetroChina and Sinopec are fine, the oil products are very good, and now they are all 92 gasoline.

This is okay, it is best to go to the regular PetroChina or Sinopec to choose to add 92 gasoline, now there is no 93.

Hello! Can be used! PetroChina and Sinopec can be mixed! It's all 92 and 95 now!

You don't think this can be mixed. In general, it is recommended that you use one type of gasoline all the time.

Hello, this one can be mixed, it doesn't matter, but now it's all 92 oil.

Hello, it is recommended that PetroChina and Sinopec can be mixed, and the outside should not be mixed.

PetroChina and Sinopec's 93 gasoline can be mixed.

Yes, PetroChina and Sinopec can be mixed!

If you don't have gasoline, you have to add it once, no problem.

Yes, PetroChina and Sinopec's 93 gasoline can be mixed.

It can be mixed, but I personally suggest that if you are not in a hurry, it is recommended to use the oil until the alarm and then replace it with another model.

It is better to choose Sinopec and PetroChina, which can be mixed.

As long as this is 93, it can be mixed

Hello, you can mix, no problem.

93 and 97 should not be mixed.

Many car owners mistakenly believe that the number of gasoline is the standard of purity and quality of the oil, and the higher the label of the vehicle, the better, which is wrong. The level of gasoline marking only indicates the size of the octane number of gasoline, and different grades of gasoline should be selected according to the different compression ratio of the engine.

Mid-range cars with compression ratios between should generally use 93 gasoline; Cars with a compression ratio greater than 97 should use 97 gasoline. At present, the compression ratio of domestic cars is generally above 9, and it is best to use 93 or 97 gasoline.

If the engine with high compression ratio uses low-grade gasoline, the cylinder temperature will rise sharply, the gasoline will not be burned completely, and the machine will vibrate strongly, so that the output power will be reduced and the parts will be damaged. If the engine with a low compression ratio insists on using high-grade oil, there will be a phenomenon of "flame retardation", that is, it is not yet the spontaneous ignition point when it is pressed to the head, and there will be incomplete combustion, which is not good for the engine.

It is not allowed to be mixed.

The higher the grade of the oil, 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 anti-knock performance. 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.

The reason why many people add high-grade gasoline is very simple, because a friend told him that high-grade gasoline is clean, and the car is more motivated to run, these are psychological effects, and the improvement of knock resistance will not bring more power to the God-only vehicle. When developing and matching the engine, the manufacturer will go through the experiment, adjustment and road test of the engine, so it is necessary to talk about the gasoline that meets the model according to the manufacturer's recommendation.

Refueling is something that every car owner will do regularly. When refueling, it is not only necessary to choose a gas station with better oil quality, but also to choose the correct gasoline label. Different grades of gasoline have different octane ratings. The higher the grade, the higher the octane number. The higher the octane number, the better the anti-knock performance.

Ordinary naturally aspirated engines need to add No. 92 gasoline, and ordinary vortex turbocharged engines need to add No. 95 gasoline. While turbocharged engines have lower compression ratios than naturally aspirated engines, turbocharged engines operate with higher temperatures and pressures inside the cylinders. Adding 95 gasoline prevents engine knocking.

Detonation is an abnormal combustion phenomenon in an engine. When the piston is in the compression stroke, the piston runs upwards to compress the combustible mixture, at which point the temperature and pressure of the combustible mixture will increase.

If the anti-knock performance of gasoline is insufficient, the combustible mixture will burn before the spark plug ignition, and the burning combustible mixture will push the piston downward, and the piston will run upwards at this time, which will lead to a decrease in the power of the engine and an increase in fuel consumption, which will also damage the engine. Severe knocking can cause the piston in the engine to burst or the connecting rod to deform.

First, the choice of how much oil to add to the car is determined according to the compression ratio of the automobile engine. It doesn't matter if you add gasoline once or twice by chance, but it's best not to mix, and if you have to mix, you should follow the principle of high rather than low. The anti-knock performance and other indicators of the standard gasoline are consistent, and the gasoline mixture has no effect on the vehicle, and the gasoline of different standards will only have an impact on the exhaust emissions of the vehicle, and will not affect the normal operation of the vehicle engine.

2. 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 No. 93 gasoline; Cars with a compression ratio greater than 97 should use 97 gasoline. Generally, the automobile engine with high compression ratio has high power and high fuel efficiency, but it is often not stable, so it needs gasoline with better anti-knock performance, and the advantage of No. 97 gasoline compared with No. 93 gasoline is that its octane number accounts for a high proportion of gasoline, and the anti-knock performance of fuel is good.

3. If the car with No. 97 gasoline is mixed with No. 93, if it is a small amount of No. 93 gasoline, the remaining part is fully added to No. 97 oil, which generally does not have much impact on the engine. If you add too much 93 oil, or even 90 gasoline, then it is necessary to put the wrong gasoline and refill the correct gasoline, because this may cause some damage to the engine and cause the engine to not work properly. If the car with No. 93 gasoline is mixed with No. 97 oil, although there is no great harm to the vehicle, there is a possibility that the gasoline burns incompletely, which is not only costly, but also a waste of resources.

<> 92 and 95 gasoline are themselves a blend, using the same base oil, both due to different octane numbers. No. 92 gasoline contains 92% isooctane and 8% n-heptane, while No. 95 gasoline contains 95% isooctane and 5% n-heptane.

If your car was supposed to be filled with lead 95 gasoline, but you add low gasoline, once or twice once in a while is not much of a problem. However, when used for a long time, the hail agitator is prone to detonation, increased carbon deposition, and the sound of metal knocking during operation may also affect the service life of the automobile ignition system, fuel injector and spark nozzle.

In general, do not frequently change the number of gasoline added to the car, try to start from the beginning, according to the instructions of the manual or the fuel cap, add as much gasoline as you want.

Mixed use will not cause major problems in a short period of time, but in a long time, knocking will occur, especially when idling, and if it is mixed for a long time, it will also lead to increased engine carbon deposition and increased fuel consumption. Suspicious shooting.

It is true that it will not have much impact on the engine in the short term, and theoretically speaking, the anti-explosion person will indeed get better and better. But don't forget, manufacturers produce engines that have their own specific performance and limits. Although you increase the grade of the fuel, which seems to improve the knock resistance, your engine will not be able to fully play the high knock resistance function brought by the high grade oil.
