Many car owners periodically arise a question - why the 95th gasoline is considered better, and is it worth overpaying. In this article we will try to figure out what gasoline is better to refuel your car, 92 or 95? And also we will analyze the majority of nuances of using one or another gasoline.
AI-92 or AI-95
The people constantly walking the opinion that a larger octane number in petrol fuel - This is the main sign of the quality and advantage of its use for the engine. This is difficult to argue with this, because looking at objective indicators when using fuel with a higher octane number, another opinion is difficult to imagine. On the 95th gasoline:The car engine begins to work more "softer";
As it turns out, the engines are designed and designed around the best gasoline, which they can process. High-performance engines use high-octane gasoline, because they need it to work with the maximum potential. Other engines can simply go by 85 or 87 octanes. Engines with turbocharging brings the greatest benefit from premium gasoline, reporting profit both in power industry and in the economy, and since today everything more cars Equipped with turbochargedows, more and more people will receive a premium.
Detonation decreases compared to other gasoline;
With a long service, you can see an improvement in the testimony in the dynamics of acceleration and some decrease in fuel consumption.
But for a better understanding of the topic of the article. It is necessary to sort out this concept - what is gasoline. This is a type of fuel obtained by distillation of crude oil. And octane number is a measure of measuring the detonation resistance of gasoline or, in other words, fuel resistance for engines internal combustion from self-ignition at high pressure.
They have every reason for this. A car designed to work with a high octane can take gasoline with a lower rating - he just did not win. Computer car will detect gas more low quality And adjusts performance for compensation. In the previous times, low-fledged gasoline meant that the engine was more prone to knocking or his fuel to burn before he suggested that the engine could kill. But the advanced electronics can adjust the time and work around it the form of detonation sensors that can detect small oscillations in the block and configure the parameters to reduce potential damage.
Also, it is worth knowing that the maximum octane number of fuel during distillation can reach the values \u200b\u200bof 93, and a higher value is given to gasoline by adding different additives of an increase in the detonation threshold.
Therefore, by virtue of the human factor, when determining the best fuel for the car. If AI-92 gasoline is created only with a distillation of oil, various additives differing in quality and characteristics can be added to gasoline AI-95. Accordingly, it is better to use a pure product than to use fuel with unknown quality.
You are traveling to a petrol station and climb along with pumps. This list continues, and all retailers offer standard and high-quality fuels. The question is whether drivers should fill their car with premium fuel? Drivers cannot help but notice that premium fuel will be significantly more expensive than standard fuel, for as many as 10 liters.
There are two main factors that distinguishes standard fuel from a chic material. The first is its octane rating, which is a way to indicate how much energy is required to ignite fuel - and, of course, not an indicator of how much energy fuel gives a car. The second is a higher concentration of cleaning products and additives to reduce friction.
Another nuance that determines the fuel for use on your car is the manufacturer's recommendations, or more precisely, the alleged type of fuel for which was designed and adjusted by the power unit of the machine.
On theoretical calculations. It can be concluded that it is impossible to increase the octane number. But with practical tests, this is not quite so. With a small difference in the octane number of the and recommended fuel used, negative consequences does not occur. Therefore, the use of 95th gasoline instead of 92th is a normal practice that increases the power and comfort from the operation of the motor. At the same time, it should be borne in mind that this statement is true only when using high-quality fuel, in which cheap additives were not used or various methods "Dilution". As mentioned above, the car will slightly improve its dynamic characteristics, and the reduced fuel consumption can equalize the cost of using more expensive fuel.
But the situation changes slightly. If the difference in octane numbers will be greater. For example: when using 92 gasoline on the motor providing the use of the 80th - this may lead to the valve during the long operation of the vehicle.
Some engines are designed to use only premium fuels. Engineers are trying to use many tricks to ensure the best combination of performance, fuel efficiency and emission levels. One of them is to optimize it to work on premium fuels, as they have a higher octane rating.
Why do the car need fuel with a higher octane? Gasoline engines Can work with several different pressures or in what is known as a compression ratio. This is the ratio of the volume of the cylinder and the combustion chamber when the piston is at the bottom of its stroke and when the piston is in the top of the chamber.
Therefore, it should not be chased for "quality", expressed in octane numbers and the cost of fuel. In some cases, it can lead to a power unit breakdown.
The situation looks completely different. When the car owner wants to save on fuel and decides to use a cheaper option and moves from the recommended 95th to the 92nd. This should not be done, and can lead to serious problems with the car engine. The main symptoms appear instantly and are expressed in:The emergence of significant detonation;
The higher the compression coefficient, the greater the mixture of fuel and air is compressed. The compression of this mixture further reduces the need for such a quantity of fuel to be injected, since more mechanical energy is extracted from it when the ignition candle is lit.
Some engines will be designed to work with a higher degree of compression than others, which means that they need a higher octane fuel to ensure that it will not ignore the engine prematurely inside the engine, which will lead to an unpleasant condition known as "knock". Resisting this pressure longer, it has a higher "activation energy".
Dynamic I. power characteristics car worsen;
Significantly increases gasoline consumption;
The motor begins to work with a noticeable effort.
Now it becomes clear that saving on fuel with a lower indicator by octane numbers can go to additional costs. And the use of the motor in this mode for a long time will lead to the need overhaulthat entails high cash costs.
How do you know if my car needs in high-octane fuel? Automakers will place a sticky label inside the door fuel tank Your car, telling drivers who grieve, the car was designed to use. If there are no stickers, check the manual car media Or call the car dealer. His service department will be able to confirm how your car was designed on the fuel. If you need high-octane fuel, you need to cut your teeth and pay the difference, as the cheaper, lower octane fuel can lead to serious engine damage over time.
The use of fuel with an increased octane number is more favorable than the use of gasoline with a reduced indicator of detonation stability from the recommended manufacturer.
In order to find out the recommended type of fuel, you can consult on the official dealer station, read the instructions for the car of your model or look at the sticker located on inner side Flashing rifle.
What if my car says he needs only low-fledged fuel? You will save a lot of money; The engine will work most effectively; And respected brand fuels will contain sufficient detergents and supplements to keep the gems of the engine with clean, suitable and durable throughout their lives.
Does the premium fuel contain any higher legislative standard? Will premium fuel be improving the savings of my car fuel? One way to try to find out whether to measure the difference in the economy between the tank filled with standard fuel, and then the tank of premium gasoline.
How to protect yourself from low quality fuel
For each car owner there is a risk of falling low-quality fuel. But the continuous use of some rules and tips can reduce this risk to minimum values.First of all, it is not necessary to constantly experiment and use the services of different filling stations. If you have found an acceptable refueling for yourself located in a convenient place, and with fuel good quality. Verified by repeated refills - should not be chased for additional benefits of 20 kopecks on a liter of gasoline and risk a car refueling for dubious or untested filling stations.
But taking into account the fact that the weather and the movement and driving conditions can vary greatly, it is unlikely to lead to meaningful conclusion. Are there any benefits for premium fuels? Nevertheless, there is a small question, uh, small font. In other words, more old enginewhich previously did not use premium fuel, would benefit most.
How to protect yourself from low quality fuel
But, as we have already spoken, the authoritative stamps of standard fuel must maintain the internal state of the engine in good condition first of all. Stick dear standard species Fuel and use only high-quality fuels, if the automaker stipulates that the engine requires it.
Also, it can be attributed to relatively safe refueling having a large network throughout the country. Large players in the fuel retail market of gasoline - no sense to deceive customers with poor quality. Therefore, in an unfamiliar place or city, it is preferable to refuel large network gas stations.
What is the best small engine or lawn mower?
Looking for the best lawn mower or fuel for your external energy equipment? Always turn fuel with extreme caution. Fuel for your lawn mowing or outdoor energy equipment must meet the following requirements.
At some refueling stations, gasoline is now sold with ethanol content up to 15%. There must be an additional brand indicating the client that if they live in a seasonal climate, they should be sure that they use the right fuel this season. You can also use a canned fuel product. . Do not mix oil in gasoline or do not modify the engine to operate on alternative fuels.
In the event that you had to refuel on dubious refueling if necessary, and all the same hit low-quality fuel, then several measures can be taken. First of all, you should not refill full tank Gasoline at an unknown refueling. You should pour exactly so much fuel that you would have enough to get to the proven gas stations with a small margin. If you poured fuel of poor quality, you can dilute it with a high octane gasoline, such as AI-98.
Using unauthorized fuel can damage engine components that will not be covered with a guarantee. If your lawn mower or equipment arise problems with running or performance problems, replace fuel suppliers or change the brands.
Fuel Recommendation for high-rise climates. To remain compatible with emissions, high height adjustment is required. Operation without this adjustment will lead to a reduction in productivity, increasing fuel consumption and increasing emissions.
In the case when the car hit the fuel of all terrible quality, without visiting the station maintenance will not cost. At the station, it will be necessary to drain all gasoline from the fuel tank and rinse the fuel system, you may have to change the fuel filters.
Fuel Storage Tips in the Small Engine
Do not know what kind of engine do you have? The properties of fuel that make up what we know like gasoline can begin to deteriorate just 30 days after the processing process. The use of the fuel stabilizer is necessary for the fuel system that is not used daily. Problems that arise due to fuel degradation are issues that are not covered by the guarantees for the engine.
Consequences of bad quality fuel
Gas is expensive, so you want to get the best wave for your dollar, but you do not want to harm your car. Therefore, it is important to know whether there is a significant difference between the various gas stamps, what differences and can cheap gas damage your car. A quick response is generally normal to use the cheapest gas you can get. However, there are differences between the various gas brands, and there are effects from the use of cheap gas.
Also, there are several ways to test the quality of fuel by handicrafts and even in the fields described in our article -.
Consequences of bad quality fuel
So it happened that in the territory russian Federation, Until now, often sellers trying to deceive consumers. This happens, including on gas stations, therefore, by refueling low-quality gasoline, you will quickly notice the first symptoms:The car dramatically loses cravings, and the impression is created about the presence of a trailer or someone in a tug;
All gas is the same
If you ever get the opportunity to see the pipeline, you will see that it carries logos from several companies. As soon as oil falls on the oil refining plant, it turns into gasoline. Oil tankers tolerate this gas in different companies, Therefore, the gasoline part however, each company according to the law is obliged to add additives to fuel. Composition, quantity and quality of additives are property. All gases contain additives, but not created equal.
Additives include detergents that help prevent education fuel injectors and deposits in the engine. Chemicals are required by law. For the most part, the difference between the fuel lies in the fact that buying a gas discount can save you a lot of money on the pump. However, gas with a large number of supplements is better coping with the prevention of engine wear. If you drive a car or do not plan to maintain a car long enough so that the engine performance is a priority, you probably think that more expensive additives are a waste of money.
An extraneous sound in the engine appears. Which is often called how - "fingers caught up";
Motor starts working with interruptions. And engine turnover on idling Lose stability.
These signs suggest that the further operation of the car with such fuel is extremely undesirable. Because, on the walls of the cylinder, pistons and valves can begin to form a nagar interfering normal work Motor. And the catalyst located in exhaust system It begins to quickly clog out, which will lead to the need for its replacement, worthy of rather money sums.
If you want to increase your engine, and you will be as much as possible, you probably want to spend a little more to get the best fuel for your car, which is available. Another option is to buy a total gas, and then add a vacuum cleaner vacuum cleaner yourself.
You will receive the advantages of the added detergents, saving money for premium gas. In addition to the difference in the amount and development of additives, another big difference between cheap gas and gas brand gas is associated with ethanol. Modern cars - These are complex machines capable of compensating fuel fluctuations, but an increase in the amount of ethanol leads to a decrease in fuel economy. If you buy a gas containing a lot of ethanol, you will not be able to do it so far from replenishment, so you actually can't save money on the pump.
Therefore, it is worth quickly solving the problem that has arisen independently or contact the maintenance station.
Additives used in gasoline
To increase the detonation resistance of the fuel intended for internal combustion engines, various additives still apply. These additives changed with the time and development of technologies, but the principle of increasing octane number remained unchanged.Until 2000, the high-octane species of gasoline included a tetraethylswin, recognized as a hazardous substance for ambient and a decrease in the resource of power units. Also, K. this type Ethyl gasoline was counted, which is already banned in most countries of the world, including the Russian Federation. But some, especially entrepreneurial, people can use tetraethylswin to increase the octane number and the reduction of the final product. But, an outdated tetraethylswin, not only pollutes the environment, and also contributes to the rapid scoring of the catalyst.
For example, fuel economy by 2-4% lower for their ethanol-containing fuels. However, some types of fuel now contain 15% ethanol, etc. Check the guide for your car, as some manufacturers actually warn about the use of this fuel, potentially dangerous for engines with high compression ratio. You can buy gas without ethanol, but its increase is difficult.
However, its presence is likely to affect your fuel line than the quantity and type of additives in your gas. For almost everyone, cheap gas means more money in your pocket and there is little chance to harm your car. If you drive a car where the smallest difference in the content of fuel, you knew it from the very beginning. You can still get a profitable deal from time to time, but it would be better to stick to the gas that your child loves to fill regularly.
Today, the fuel industry uses ethanol or substance based on it. In fact, it is an ordinary ethyl alcohol that does not cause negative consequences for the environment. And modern gasoline AI-95 consists of 10% of ethanol based substances, allowed to implement in the entire world.
Application of gasoline AI-98
Not all car owners are aware that gasoline with a high octane number offered on many gas stations, or rather gasoline of the AI-98 brand. Designed for forced power units. Which are used in sports or expensive cars Premium segment. And the use of it on motors not intended for him - it may entail negative consequences expressed by unscheduled repair, as well as the economic unjustification of the use of such fuel.
Output
As it became clear from the information received - each internal combustion engine is designed under a certain type of fuel. From this it follows that the use of gasoline with an excellent octane number, in most cases, does not be beneficial, and can cause unscheduled overhaul of the motor. But the use of gasoline with a small difference between the octane number in the most side is allowed.Therefore, to the question of which gasoline is better than AI-92 or AI-95, it is possible to answer as follows: "The degree of quality of fuel for the engine is not determined by the number of octane numbers, and it is impossible to answer this question. But the use of gasoline of the AI-95 gasoline, in some cases, leads to an improvement in the characteristics of a car power unit, without consequences for its resource.

› All about 92, 95, 98 gasoline. What gasoline is better?Hello everyone!
Long time I wrote, because of the lack of time. But the other day I drove to refueling and suddenly there was a question, and what is the difference in gasoline 92 and 95 (well, in addition to the price of course)! Searching for an Internet found an interesting article!
Material took from here from here, as well as thanks for this interesting article about gasoline
What will happen if pour into the car 95 or 98 gasoline if she need 92 gasoline on the passport?
Before considering this question, it is necessary to understand what is an octane number. By scientific language, octane number - This fuel property is to resist the process of self-ignition during compression in the engine combustion chamber. This parameter is also called detonation resistance.
The digit of the gasoline mark means its octane number, i.e. and more octane number in the gasoline brand the more detonation-resistant.
"Research" and "Motor" methods. Both in the form of "Research" - are determined on the same installation, but the first at small revolutions (you buy it on the gas station) and the second - on elevated - these figures are known to a little. In addition, on the engine method, the mixture is heated strongly - up to 149 degrees - make it more prone to explosion.
Detonation - This is an independent ignition of gasoline on the degree of compression. The internal combustion engine compresses the mixture of gasoline and air in the cylinder, and each engine is designed for a certain compression ratio.
VAZ engines are available with a compression ratio 9.0 or 9.9, this compression ratio is designed for gasoline grade 92, i.e. This gasoline will not flamm in the engine itself, and the flash will only happen from the spark.
Engines designed for gasoline 95 or 98 or 102 will have even greater compression ratio.
Fuel detonation - Motor harm.
The consequences of detonation explosions are very sad:
- accelerated motor wear;
- overheating;
- Local destruction of the power unit is possible.
All this is accompanied by a noticeable reduction in thrust and power, high flow gasoline, dense smoke from exhaust pipe etc.
Sometimes there are cases when the engine is faded by the ignition key, and for some time it still works at idle, it suggests that the low-quality 92 gasoline poured, or 80 gasoline flooded, and he himself flammives from compression, usually when driving on such gasoline in the engine when accelerating or moved the mountain appears a clinking like a knock of valves, but the valve here is neither and this is detonation in the engine and this gasoline flammifies ahead of time and trying to break the piston partitions and piston rings. But also such a ringing can be on good gasoline But with a very early ignition, but the engine will be sick immediately. Also, gasoline may light up because of the spark plugs or a car that is split and the gasoline flames itself in the cylinder itself, this is a very rare case.
Is it possible to pour into the engine intended for gasoline 92, gasoline 95, 98?
Based on the above, the gasoline poured into the engine with a large octane number, the engine decreases the possibility of spontaneous ignition of gasoline in the cylinder, which is very good for the engine.
Therefore, if you have extra money to refuel your car, then pour gasoline into it at least 95, 98, the engine will be only better.
It makes it possible that if you pour into the engine intended for 80 gasoline 92 gasoline or above, the pistons will run out, all these are false information, the pistons will not bargain, but it will not be strong, since these engines with a small degree of compression.
Why is 95 gasoline stronger 92?
Gasoline 80 burns a very sharp flash and low burning duration, such as a sharp impact. Gasoline 92 will already have a softer outbreak and a little greater burning duration, that is, a little longer, the piston and gasoline 95 will have an even softer flash and the piston will push it longer. It follows that the more octane number in gasoline, Moreover, it lights up and pushes the piston longer, which increases the power of the engine. Usually when moving in a straight line, the increase in power due to high-octane gasoline is not very felt, but the machine is driving a much abroad and easier. If you pour gasoline with a larger octane number, then for the engine will only be better, therefore, if there is an opportunity in money, then pour more expensive gasoline.
Is it possible to mix 92 and 95 and 98?
Yes, you can mix these gasoline.
How to distinguish gasoline 95 from 92 at home?
You can determine by smell, 95 gasoline has a sharper smell, 92 gasoline is less sharp.
Is it possible without harm to the engine to move from the 95th gasoline to the 92nd in order to save?
Currently, gasoline prices are only rising, and nothing expects to end this process. For this reason, many begin to think about saving fuel. As a rule, the option of gasoline refueling with a lower octane number comes to the mind immediately than the manufacturer.
Therefore, many car owners begin to "feed" their "iron horse" by 92-M gasoline instead of the 95th. But this approach can lead to unpleasant consequences and great expenditures. You can pour 92th gasoline into a car tank, but is it necessary?
Ghost savings
Naturally, some savings from it will be, as the 92nd gasoline is still cheaper than the 95th. However, it is necessary to take into account not only this factor. After all, due to the low quality of fuel, the combustion of the mixture will be less effective, which will immediately affect the reduction of car power. In addition, if the bus owner loves a dynamic ride, the flow rate will most likely be even higher than when refilling with normal fuel, it burns low-fledged gasoline worse, so the motor appetite rises.
Consequences refueling cheap fuel
Old engines are much less sensitive to changes in the octane number, so refueling machines with such force aggregates may be quite justified;
It is not a fact that the transition from the 95th gasoline on the 92nd will help save large amounts of money, because the difference in their cost is not so great.
And how to understand whether I need AI-98?
I repeat, the main factors are: the degree of compression is above 10, a controlled thermostat, turbine, frequent movement of "gas to floor". At least once they said "yes" is your choice. As a rule, if a sports car is generally without conversations. Open the hatch, and everything is there.
Other things being equal than the higher resistance to detonation, the usually slower the burning speed and the above efficiency of this process, better efficiency. In practice, this may mean a more smooth engine operation and a slight improvement in efficiency and power. Usually, in the range of 5-7% - the best varieties of sports petrols can add 10%, but it is already a huge difference.
Real improvements will be largely related to the actual composition of fuel - modern gasoline is the same "cocktail".
A simple example: Probably, many have seen how smoothly the car is working on oil gas - propane-butane. Its octane number above 100. It would seem - excellent fuel. But there is one feature - the fuel is less calorie, less energy is distinguished from its combustion. 10-15%, with all the ensuing consequences - the above fuel consumption, less power.
In AI95 and AI98 "Full of additives". I have such a nagar on the candlelight, but also a neighbor spoke ...
Yes, as many as 5-7 percent of alcohol. Harmless. In the worst case. In modern isomerization gasoline and that may not be. Any nagar on your candlelight (if it is not red) to gasoline is hardly related to the gasoline.
We now have a lot of gasoline with some kind of washing additives - maybe this is something harmful? Do they really raise power? Due to what?
The presence of detergent additives is the requirement of the standards of Euro4 and Euro5. Without them there is no. Nonternatives. In extremely minor over the amount of quantities, in such gasoline there are substances that remove Nagar in fuel system And, for example, from the valve group, where in Nagaru is definitely not a place. Another question is that it is usually called loud names like "Super-ECTO-Power Sport", compared with the usual fuel of a lower octane number, which is clearly written with small font. For example, 5-7% of the power increase from BP Ultimate AI-98 are guaranteed against the background ... normal AI-95. One convenient - see the fashionable name - it means for sure not lower euro4.
At some refills there are AI-100 at a triple price - is it cool?
Easier simple - if in the documents on such fuel the number of the engine method is real 90, or even higher - possibly cool. But if all the same "88" glows - in front of you a little "dispersed" AI-98 in a space price. Sometimes on a decent refueling you can find AI-98 with a motor number about 90 - this is exactly cool and inexpensive. And also, beautiful photos of Ferrari machines and others are confused: Remember - anti-knock properties do not guarantee big power Compared by a lower octane gasoline. In the composition there is no single parameter that could be unambiguously tied to power from gasoline, and not from the characteristics of the motor itself. Motor, which will require high-octane gasoline - most likely powerful. But high-octane gasoline itself can give up the heat of the burning of a lower variety gasoline. Good sports fuel can give a tangible increase and with detonation will be all right, but it costs completely different money and sold in special stores.
We have bad gasoline?
No, in most cities on branded gas stations, gasoline is proposed as sufficient, so as not to think about this problem at all. If you had problems of any kind related to the engine repair, then most likely they arose completely for other reasons.
