Will the throttle really be light when the car is added to 95 gasoline?

There is something in gasoline called isooctane, which determines whether the internal combustion engine of the car can withstand riots. Isooctane is an inert substance, with a content of 95% in gasoline, which can reduce the problem of deflagration during compression. This is related to the service life of a car.

It is marked that the car with No. 92 oil has a low operating speed of the internal combustion engine and does not have an excessively high pressure ratio. No. 92 oil in the cylinder is not harmful to the car's internal combustion engine. If 95 liters of gasoline are added to it.

It has no effect on the car itself. It is possible to protect the engine.

After adding No. 95, I obviously feel that the power is better, in fact, what I want to say is not that the engine is obviously screaming, but in some details have been improved, such as the engine runs more smoothly when the throttle is small at low speeds, and the gearbox shifts are particularly smooth, and the frustration at low speed is obvious when adding No. 92 oil. And after adding 95, the acceleration response is very fast, and the engine sound is also bright.

No. 95 gasoline is purer and better, and 95 gasoline has more isooctane content, so the anti-knock performance of the car with 95 gasoline is also much better, and the gasoline can be burned more fully and the efficiency is also high. No. 95 gasoline is 95% isooctane and 3% n-heptane. When the engine compression ratio is high, high-octane gasoline should be used, if the compression ratio is high, low-octane gasoline will cause abnormal combustion, resulting in shock, fuel consumption and driving weakness.

Adding 95 gasoline reduces the chance of knocking in the engine and can slightly increase the engine's power. The octane number of gasoline is different between different grades, and the octane number of 95 gasoline is higher than that of 92 gasoline, and the octane number can improve the stability of gasoline. In fact, with 95 gasoline, the car has significantly improved its operation, but the throttle is not light.

This is related to the service life of a car. It is marked with a car with No. 92 oil, and the speed of his internal combustion engine is not high.

If 95 liters of gasoline are added to it. It has no effect on the car itself. It is possible to protect the engine.

Light! No. 95 and No. 92 are not the same level!

It is marked with a car with No. 92 oil, and the speed of his internal combustion engine is not high.

Plus 95 cars are generally mid-performance cars, and most of them use turbocharged engines. The proportion of 95% gasoline in n-heptane is 5%, and the proportion of isooctane is 95%. Its excellent anti-knock performance makes it suitable for full combustion of this type of engine.

Gasoline 95 is a gasoline composed of 95% isooctane and 3% n-heptane. When the engine compression ratio is high, high-octane gasoline should be used. If the compression ratio is high, low-octane gasoline can cause abnormal combustion, resulting in knocking, fuel consumption, and driving weakness.

You can't fill up in the summer. If the gasoline is too full, the temperature will be high in summer, and the car itself will heat up. Gasoline expands and contracts in heat, the car shakes constantly when it starts, and gasoline evaporates rapidly in the form of gas or even liquid.

Plus, it takes a long time. Gasoline can also deteriorate, leaving a hidden danger for its own safety.

In fact, the gasoline is blended out of No. 90 **, and the reason why there are 92 95 these marks is because other different additives are added, and the purpose of adding additives is mainly to solve the problem of anti-knock of gasoline. The difference between high and low grade gasoline lies in the octane number. Different octane number means different knock resistance.

Moreover, the designation here has nothing to do with how pure they are.

Then it is okay to add 92 gasoline before, and later change it to 95. However, it is best to choose the gasoline label used in the vehicle according to the instructions of the car. What kind of gasoline a car uses has a lot to do with its engine matching, which is fundamentally determined by its compression ratio.

The higher the compression ratio, the more power and efficiency, but the less stability it is, so gasoline with better knock resistance is required.

Which label is better? Don't be entangled, there are instructions in our car fuel tank cap, and it is recommended that we add as many numbers as we want. In addition, the grade of gasoline added to the car is also related to the compression ratio of the engine.

The higher the compression ratio, the higher the gasoline grade used.

If the power is strong, it is required to add 95 gasoline, it is definitely not possible to add 92, because the oil number is not enough, but the engine is wasted, and the reverse is the same, it is required to burn 92, and the cost of adding 95 is not only inexhaustible but also high, which also has a certain impact on the car itself.

It should be better, after all, the gasoline of No. 95 burns better

Qualitative petrol will not give you more power because the power depends on the engine, but in order for a high-power engine to work, it needs high-quality petrol that can withstand pressure and temperature, and if you have a high-performance engine, then choose better petrol in terms of power. Is 95 petrol really better for your car, in this article, we will compare grade 95 and 98 petrol to find out if you are wasting money on premium petrol. Most drivers consider 98 petrol to be more expensive than 95 petrol because it is of higher quality and is more suitable for your car.

The cost of 98 gasoline is indeed much higher, and for a typical car, filling up 98 gasoline can be more than 120 yuan more than using 95. What is the real difference between premium petrol and regular petrol, we will go through this question once and for all by evaluating the two petrol grades based on a series of criteria.

The main difference between 95 petrol and 98 petrol is knock resistance. "Knocking" is the thump you make in the engine when the gasoline inside can't resist the high pressure and unexpectedly**. If it only happens once or twice, it's not a problem, but if it regenerates over time, your engine could suffer serious damage.

98 gasoline is more stable, resistant to knocking, and is a better choice in terms of engine protection.

95 gasoline will also work, but if your engine is powerful, it will use higher pressures that 95 gasoline may not be able to withstand. If you want to be on the safe side, 98 petrol will provide better protection for your engine. Engine repairs can cost up to $2,000, far more than the savings with 95 gasoline!

In the long run, 98 gasoline wins when it comes to engine protection.

It is a common belief that good quality gas gives your engine more power, probably because a high-performance engine usually requires 98 gas, but that doesn't mean that adding 98 gas to a normal performing engine will give you more power. High-performance cars are built for speed, with a 0-96kmh acceleration time of less than 10 seconds, for which the engine uses very high temperatures and pressures. 98 gasoline can withstand this, allowing the engine to extract maximum power from the fuel and run at maximum power.

If you substitute 95 gasoline, it will ** too quickly under pressure.

Another common perception about premium gasoline is that it lasts longer, and you can save money on gas costs over time. This may be true in some cases, but not always. 98 gasoline is less likely to be wasted in uncontrolled combustion, which does provide more mileage, but overall, the difference is minimal.

Some drivers do claim that the 98 gives them more mileage, but this may be more due to their vehicle and driving habits than the fuel itself. In terms of mileage, the 95 and 98 are about the same amount of gas, and although the 98 is a little better, the difference is not necessarily worth spending a little more.

This is not necessarily, because some cars are suitable for adding 95 gasoline, and the power will be better, and some cars are not suitable, and the power will not change, so this result is not accurate.

No. 95 gasoline is a bit purer than No. 92 gasoline, but the car should be filled with the oil that matches its engine. Blindly adding 95 oil can be counterproductive.

This is true, because high-grade gasoline is more thermally efficient and will have better power.

Many friends will think that No. 95 gasoline.

More resistant to burning, although 95 is more gasoline than 92.

A few cents more per liter, but a tank of 95 petrol is better than 92 petrol.

The mileage is farther, the average cost per kilometer is about the same, and the quality of 95 is better than 92, which leads to many vehicles that can add 92 gasoline to choose 95 gasoline, the truth is really that 95 gasoline is more resistant to burning?

1. From gasolineCalorific valueHigh and low to judge

First of all, we must know that No. 95 gasoline is blended by No. 92 gasoline, there are two additives we commonly use, the first is MTBE, you can get No. 95 gasoline by adding a certain proportion of MTBE from No. 92 gasoline, and the calorific value of No. 95 gasoline blended with MTBE will drop approximately, it is said that MTBE is toxic, and many refineries no longer use MTBE additives. The second is the addition of aromatic hydrocarbons from No. 92 gasoline.

No. 95 gasoline is obtained, and the calorific value of No. 95 gasoline using this additive is about 1% higher than before. As a result, No. 95 gasoline is more resistant to burning than No. 92 gasoline.

Judging by the knock resistance

The engine operation is inseparable from various sensors, and there is a detonation sensor inside the engine, the detonation sensor can adjust the ignition advance angle in real time by detecting the engine detonation, the earlier the engine ignition, the higher the engine efficiency, the more adequate the fuel combustion, the more resistant the gasoline is, the engine that should add 95 gasoline, you add 92 gasoline, it will cause the engine to knock, and the detonation will be suppressed by delaying the ignition advance angle, at this time, the fuel combustion is not sufficient, the power is reduced, and the carbon is deposited.

The more it is, the more fuel it costs.

How to choose the right oil

1. It is recommended to add 92 gasoline to the vehicle with 95 gasoline, which is completely OK, the engine power may be improved, but it is not obvious, the expectation is not too high, it may save fuel, but it does not necessarily save money.

2. It is recommended to add No. 95 gasoline to the vehicle plus No. 92 gasoline, no, the engine will produce knocking, affect engine power and fuel consumption, increase carbon deposition, and damage the engine.

3. It is recommended to add 92 gasoline to 92, which is both economical and burn-resistant.

4. It is not recommended to add No. 98 gasoline to family cars.

Unless you're going to drive it as a sports car, it's expensive.

5. When buying a car, it is recommended to buy a model that can add 92 gasoline, which is both burn-resistant and saves money.

It's true, because there are a lot of cars now that are filled with 95 gasoline, and this kind of car with 95 gasoline as standard, if you have to add 92, it will not burn enough and the fuel consumption will be higher.

I have been using 92 oil, and after replacing 95, the power is better and the fuel consumption is lower, because the ECU knows that you have changed the oil.

I don't think this is true, because although the 95 petrol is more pure, it will only make the car more powerful during driving, and will not make the car more fuel-efficient.

That's exactly what it looks like, because the No. 95 car is more resistant to burning, and it's actually more economical.

The short-term mixing of gasoline of different grades will not cause great harm to the car, but the long-term mixing will affect the service life of the ignition system, fuel injector and spark nozzle of the car, so that the overhaul time of the vehicle will be advanced.

Strictly speaking, 92 gasoline and 95 can not be mixed, but the chemical composition of the two of them is relatively close in all aspects, strong anti-knocking, the two are generally not a big problem, after mixing different grades of gasoline in a short time, there is generally no need to carry out special maintenance on the vehicle, but it is recommended that the owner should use the corresponding label of gasoline in strict accordance with the requirements of the vehicle itself if conditions permit. ”

If you really want to mix, you should follow the principle of high and not low.

For example, the original 92 oil car with 95 oil will not be a problem, but on the contrary, it may lead to damage to the vehicle, if the car uses low-grade gasoline may cause vehicle knocking, serious may lead to vehicle valve bending, valve cover damage and other problems.

The main difference between No. 92 and No. 93 is that the limit of sulfur content is reduced from 50 milligrams per kilogram to 10 milligrams per kilogram, and the limit of manganese content is reduced from grams per liter to grams per liter. At the same time, the octane number and anti-knock performance of gasoline have been reduced, and the anti-knock index of No. 89, 92, 95 has been revised to "not less than".

Does a high grade equal good motivation? Is a high grade more fuel-efficient?

After gasoline upgrading, why does fuel consumption increase and power shortage? According to the analysis of industry insiders, the upgrade of the quality of national five gasoline oil is accompanied by the adjustment of the label, and the oil label represents the performance of the oil, the higher the label, the higher the octane number, the better the power performance provided for the car, and the lower the fuel consumption. However, with the upgrading of oil quality, the sulfur content is greatly reduced, and at the same time of reducing the sulfur content, part of the octane number needs to be consumed, so the oil label will be slightly reduced, and the fuel consumption required to produce the same kinetic energy will increase slightly.

In the owner's manual of new domestic cars, No. 92 gasoline is recommended. Only in luxury brand models is it recommended to recommend the use of 95 gasoline. And only luxury brands such as Porsche will mainly recommend No. 98 gasoline.
