Can 93 gasoline and 97 gasoline be mixed

No, it will affect the performance and life of the engine.

No. 93 and No. 97 are better not to be mixed. Because the additives and chemical composition of gasoline are different for different grades. No. 93 gasoline is a low-grade oil compared to No. 97 oil, which is often mixed, which will cause insufficient power, insufficient combustion, affect the service life of the spark plug, and bring more exhaust pollution.

93 and 97 can be mixed, and the effect is that the mixed fuel grade is higher than 93 and lower than 97. There are 95 oils abroad, which is actually equivalent to that effect, of course, it depends on the mixing ratio of 93 and 97. But it is not recommended to refuel in this way during the use of the vehicle, the current car computer has a learning process, often use 93 gasoline, then the ignition timing of the computer is fine-tuned to adapt to the state of 93 oil, suddenly changed to 97, the computer needs a certain amount of time to adapt, and vice versa.

Therefore, it is recommended that you fix a label for long-term use according to the manufacturer's requirements, which is better for the car.

Hello. There is no problem with the occasional mixing of 93 and 97 gas. It is recommended to use one of the gasoline.

In the case of a vehicle with turbocharging, it is recommended to use 97 gasoline. The power will be a little stronger. A fully burned engine will have less carbon deposits.

If there is no turbo configuration, you can use 93 gasoline to meet your vehicle, I hope mine can help you, I wish you a happy car [car questions, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, you can't mix, the octane number of 97 and 93 gasoline is not the same, and it is not recommended to mix. I hope it can help you and I wish you a happy car. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Because 93 gasoline and 97 gasoline are quite different in anti-knock performance, mixed gasoline reduces the octane number, benzene content, olefin content, sulfur content, oxygen content, induction period, and initial point of gasoline to a certain extent, but considering that the current gasoline does not meet the national standard at all when it leaves the factory, the quality itself is low, and after mixing, the vehicle will have insufficient power and high fuel consumption, which will definitely affect the engine. On the surface, there will definitely be no other problems, and you will not be able to see it for a while and a half, maybe after one to two years, your engine will be weak, and you will know when there are various problems.

Hello, you can mix it, it's okay a few times once in a while, but it is not recommended to use it like this for a long time.

If your car requirement is 93, you can mix it up casually, no problem. My if it helps you, please set it to the best, thanks!

It's better not to mix them.

It's not safe to mix this thing.

Theoretically, it can be mixed.

The so-called No. 90, No. 93, and No. 97 unleaded gasoline refers to the fact that they contain % of the "isooctane" with strong detonation resistance, that is, they contain % of the n-heptane with poor detonation resistance.

Therefore, the octane number has become an indicator of the ability of the gasoline engine to resist knocking. The engine should be used with 97 gasoline, and if 90 gasoline is used, of course, it is prone to knocking.

Theoretically, there is no problem with the first foot, in fact, this situation is very common, in the place where the 97 can not be added, the owner has no choice but to add the 93, and the original 97 of the fuel tank is mixed together.

Not to mention that the 93 and 97 are mixed together, even if you mix gasoline with diesel, as long as the engine is not too high-tech, there is no problem to drive in the short term (of course, it will be extremely harmful to the car in the long run). I've seen the relevant tests, gasoline car plus diesel, ran hundreds of kilometers, ran very well; The diesel car is equipped with Tanqin gasoline, and the short-distance run does not make it a big problem.

It is best not to mix No. 93 gasoline with No. 97 gasoline, because it does not matter if different grades of gasoline are added once or twice, but it is best not to mix. 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.

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.

Gasoline labeling is related to octane number.

The number of oils used is related to the compression ratio. The compression ratio is 7 5 8 0 should be used 90 car gasoline; The compression ratio is 8 0 8 5 should be used 90 93 car gasoline; The compression ratio is 8 5 9 5 should be used 93 95 vehicle gasoline; The compression ratio is 9 5 10 should be 95 97 car gasoline. Generally, the compression ratio can be found in the car manual, and in addition to the manual, the car manufacturer will also mark the recommended fuel label on the inside of the fuel tank cap.

The owner should strictly follow the different compression ratios of the automobile engine and choose the corresponding grade of automotive gasoline in order to make the engine play the best performance.

If unleaded petrol is used in a lower number than the specified requirement, the engine will detonate. Generally, it occurs during rapid acceleration and climbing, if the engine has a long-term knock due to the low gasoline grade, it will damage the engine, and even damage the piston and cylinder block.

However, the choice of gasoline is not the higher the grade, the better, the main basis for the choice of gasoline label is the compression ratio of the engine. Parameters such as compression ratio and ignition advance angle have been set in the engine computer, and the owner has no problem choosing gasoline in strict accordance with the requirements of the instructions. The blind use of high-grade gasoline will not give full play to its advantages of high anti-knock performance, and will also cause a waste of money.

1. The fuel used should be selected according to the compression ratio of the automobile engine, and the higher the grade, the better.

3. Since the composition of No. 97 gasoline and No. 93 gasoline is not exactly the same, it will cause certain adverse effects on the engine during the replacement process, so it is recommended not to change the fuel number frequently.

4. I don't know why you want to talk about gasoline from 97 roundabout 93, from my driving experience, it actually costs about the same with these two marks of gasoline. Although No. 97 oil is more expensive, it feels like the actual cost per 100 kilometers is about the same as No. 93 oil.

It's best not to mix them!

It depends on the gasoline label required by the original car, if it is required to use 97, it is not good to mix 93; The requirements for some supercharged oil products are strict, and the oil circuit and fuel injection head should be cleaned in time after mixing; It doesn't matter if you mix 97 with 93, it's just a bit wasteful. In the case of gasoline itself, it is completely possible to mix with different labels.

Choose the right gasoline label.

Many car owners mistakenly believe that the label of gasoline is the standard of purity and quality of the oil, and that the higher the label of the vehicle, the better the gasoline, 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 should be cautious about using 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 chooses low-grade gasoline, the cylinder temperature will rise sharply, the gasoline will be incompletely burned, 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.

Therefore, it is recommended that it is best not to mix combustion, try to use gasoline suitable for the label, accidentally mix the two fuels, the problem is not big, and you can add back the original oil number after use.

It's best not to mix this, because mixing will affect the power of the car and its combustion, hope!

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

Gasoline (ULP), which is a transparent liquid in appearance, is mainly composed of C4 C10 hydrocarbons, and is divided into three grades: 90, 93 and 95 according to the research octane number.

It has a high octane number and excellent anti-knock resistance, and is used in carburetor gasoline engines with high compression ratios, which can improve the power of the engine and reduce fuel consumption; It has good evaporation and combustibility, which can ensure that the engine runs smoothly, burns completely, and has less carbon deposit; It has good stability, is not easy to appear early oxidation and deterioration in the process of storage, transportation and use, and is non-corrosive to engine parts and oil storage containers.

According to the manufacturing process, it can be divided into straight-run gasoline, hot cracking gasoline, catalytic cracking gasoline, reformed gasoline, coking gasoline, superimposed gasoline, hydrocracking gasoline, pyrolysis gasoline and alkylated gasoline, synthetic gasoline, etc.

According to the use, it can be divided into three categories: aviation gasoline, vehicle gasoline, and solvent gasoline. It is mainly used as a fuel for gasoline engines. It is widely used in automobiles, motorcycles, speedboats, helicopters, agricultural and forestry aircraft, etc. Solvent gasoline is used in rubber, paint, grease, spices and other industries.

Gasoline can also dissolve substances that water cannot dissolve, such as oil. It can play a role in cleaning oil stains.

As an organic solution, gasoline can also be used as an extractant, and the most widely used as an extractant is the mainstream production technology of soybean oil in China: leaching oil technology. The operation method of leaching oil technology is to soak soybeans in No. 6 light gasoline and then squeeze oil, and then after a series of processing to form soybean edible oil.

It's okay, you can add it like this, as long as it's not less than 93, don't worry.
