What kind of gasoline is better to fill? Which gas stations should you refuel

Despite constant claims that a transition to new, environmentally friendly fuels is necessary, gasoline-powered cars remain in the majority. And many owners of such cars ask themselves the question: "What is the best gasoline to refuel vehicles?" After all, several brands are present at gas stations at once.

Octane number and cost

The numerical value in the marking indicates the octane number of the fuel. The higher the value, the better the detonation resistance. So, 95 gasoline, in comparison with AI-92, will have a higher quality. Accordingly, the higher the octane number, the higher the cost.

The brand name also contains alphabetic values. "A" indicates that the fuel is intended for use in vehicles. "I" means that the octane number was determined by the research method (it may not be present, in this case the measurement was carried out by the motor method).

According to GOST, fuel in Russia is divided into several main groups:

• AI-80
• AI-92
• AI-95
• AI-98

So, the question of what octane number 92 gasoline has is resolved. Now it is necessary to consider the features of the production of AI-92.

What is the difference between AI-92

Gasoline 92 is a high-octane fuel designed for use in carburetor and injection vehicles. The main difference between 92 and 95 gasoline is that it has a lower octane number. This type of fuel is produced in two versions: summer and winter. This option is somewhat cheaper than the AI-95 (by about 3-4 rubles). It is often recommended by car manufacturers as a backup option for vehicles running on higher octane gasoline.

Differences AI-95

This type of fuel has an octane rating of at least 95 according to the research method and 85 according to the motor. A liter of this gasoline is more expensive than a liter of AI-92. However, it will be more profitable to use it, especially when driving around the city. The reason is that the fuel consumption will decrease. On the track, this effect is almost unnoticeable.

Old cars feel very good when using 95th gasoline. Their acceleration is improved, power and maximum speed are slightly increased. On new models of motors, the effect is not so noticeable (although it is still present). So the question of which gasoline is better than 95 or 92 to fill in the gas tank must be decided by the motorist himself (unless, of course, there are no restrictions on the part of the vehicle manufacturer).

Quite often you can hear calls to use the AI-98. Although, it is quite difficult to notice the difference between 95 and 98 gasoline when driving a regular car. The fact is that the AI-98 is designed for turbocharged engines. With such an operation, the effect will indeed be significant.

95 or 92 gasoline: how to refuel a car

When choosing a fuel, you need to follow the manufacturer's recommendations, not personal preferences. In this case, the question of which gasoline to pour 92 or 95 will disappear by itself.

WATCH THE VIDEO

The brand of fuel used on a particular car model is indicated under the fuel tank cap. If you use the other option, it will void the warranty of the car.

The octane numbers of 92 and 95 gasoline are different, which means that the properties will be different. High octane fuels will have a lower flash point. Therefore, only a higher type of gasoline can be poured into a car. Real 95 gasoline poured into a car that drove a 92 will not affect the condition of the engine in any way. On the contrary, the performance of the car will only improve.

Filling in fuel with a low octane number is not worth it. This will lead to a reduction in the resource of the unit. Although, in case of emergency, this option is acceptable (but only for a short period of time). Therefore, if the question arises: "Gasoline 92 or 95 which is better?", Then the answer is obvious.

Difference when switching to a new brand of fuel

The temperature and burning rate of gasoline 92 and 95 are different. Therefore, after changing the brand, the motorist should immediately feel the change in the car's traction. Although the difference will be so insignificant that only an experienced driver will most likely notice it.

The car owner can determine at home what kind of gasoline is in front of him. To do this, it is necessary to measure the density of the liquid. You can also look at the color of the fuel (it is dyed during production):

1. A-76 is a cloudy, opaque liquid. In this case, it is not about dyes: the fuel is of relatively low quality and contains a large number of impurities.
2. AI-92 has a red-orange color.
3. AI-98 is usually blue.

Can 92 and 95 gasoline be mixed?

In order to save money, or for some other reason, many drivers mix different brands of fuel. Among car owners, there is still an active debate about what kind of gasoline can be poured into the gas tank.

In most cases, the octane number is increased by the addition of additives. That is, a lower-octane fuel is taken as a basis (there are most of 92 gasoline bases) and brought to the AI-95 or AI-98 standard.

It must be remembered that 98 gasoline differs from 95, as well as from 92 in its density. That is, if you fill in two different grades of fuel, then the grade with a low octane number will be at the bottom of the gas tank. In this case, mixing will not occur. That is, one gasoline will be produced first, and then another. There should be no problems with the operation of the motor (unless, of course, the octane number is higher than the one set by the manufacturer). But nevertheless, it is better to fill in any brand of gasoline separately.

For many modern cars, it doesn't matter which gasoline is better to fill up with 92 or 95. The main thing is that it is of good quality. Checking fuel is easy enough. It is required to apply a drop to a piece of paper. If a stain forms after drying, it means that there are impurities in the composition (for example, it can be kerosene). The quality of such gasoline will be lower than that of standard gas.

This method is suitable for checking various brands. You can also check the fuel for water in it. This will require potassium permanganate. It will not dissolve in pure gasoline. However, if it has been diluted with water, the powder will immediately mix with the contents of the container.

Sometimes the content of hydrogen sulfide in the fuel can be exceeded. This is evidenced by the strong smell of rotten eggs emanating from him.

If you often have to refuel at unfamiliar gas stations, you may need to check the octane number. For this, there are special devices that determine this indicator for a small portion of liquid. The devices are small and can be carried with you.

Starting this little research from the premium segment, you can ignore a few traditional exclamations on the topic “Will someone, buying a car for 3-5 million, think about saving gasoline?”. Yes, it will - many buyers value moderate consumption in their car and an adequate cost of the monthly ration. Therefore, recalling the unpretentious representatives of the "premium" is a very urgent task.

However, I managed to remember very few of them - more precisely, only one. Of course, it would be too optimistic to expect from modern engines of the "German troika" or "Japanese two" the possibility of consuming 92 gasoline. But at first glance, less demanding "Americans" like all Cadillac models and the overwhelming majority of Jeep want to see in their tank fuel with an octane rating of at least 91 according to the American standard - that is, the equivalent of the Russian AI-95. Yes, even "mammoths" like the Grand Cherokee, Escalade and Tahoe suggest a 95 in their huge tanks. The only exception is the Jeep Wrangler, which is ready to run on unleaded gasoline with a RON 91 minimum.

Middle segment

In the middle segment of cars that allow you to save on gasoline by a couple of rubles per liter, of course, there are more - here the class already allows you to have this characteristic among the competitive advantages. Nevertheless, no one particularly emphasizes the ability of cars to digest 92nd gasoline - as a rule, you can find data on the type of fuel only in the operating instructions.

Under the hood of the Ford Kuga "2016 – present.

For example, Ford has such data. The manuals of Fiesta, Kuga, EcoSport, Explorer and others clearly state: use unleaded gasoline with an octane rating of at least 92. In the Mondeo manual available on the website, however, the American standard AKI with an octane rating of 87 is indicated - but it also corresponds exactly to “our "AI-92.

In the photo: Ford Fiesta "2017

At Honda, unlike many others, the type of fuel used is spelled out directly on the website, among other technical characteristics. It seems that the fact that this fuel is AI-92 contributed to this in part. Gasoline of the "Regular" class is recommended for both Pilot and CR-V with both 2 and 2.4 liter engines.

Photo: Honda Pilot "2015 – present and Honda CR-V" 2016 – present.

Another Japanese manufacturer, Mitsubishi, also has "omnivorous" cars in its arsenal - albeit only two. This is an age-old, but this and much more recent Outlander: they have the mark “AI-92” in the “Fuel Type” column, while the new Pajero Sport is no longer satisfied with this gasoline.

In the photo: Mitsubishi Pajero "2006 – present.

Nissan has a similar situation: here only in the description of the budget Almera it is clearly stated that you need to fill in unleaded gasoline with an octane rating of 92. All other gasoline models modestly indicate "gasoline" as the fuel type, moreover, there are no operating manuals on the site, as well as clear guidelines in brochures. A long search leads us to what logically follows from this unknown: all other Nissan models prefer 95th gasoline.

Under the hood Nissan Almera "2012 – present.

The situation with Toyota is even more interesting. Here, the recommended fuel type differs not only between models, but even within the same model equipped with several motors. So, Corolla with base engines of 1.4 and 1.6 liters can only be refueled with gasoline with an octane rating of 95 and higher, but the older 1.8-liter engine can also digest an octane rating of 91. This looks doubly interesting against the background of that that the compression ratio in engines 1.6 and 1.8 is almost the same - 10.2 and 10, respectively. But for Camry the situation is the opposite: the younger engines of 2 and 2.5 liters digest 92nd gasoline, while the V-shaped "six" requires 95th. The same situation with the Land Cruiser Prado: the 2.7-liter unit "eats" the 92nd, and the four-liter engine is the 95th. And off-road vehicles represented by the RAV 4 and Highlander, led by the Land Cruiser 200, can consume "cheap" fuel in all petrol versions. Concluding the conversation about Toyota, it is worth noting that it also saves money not only thanks to the hybrid transmission, but also due to the price of fuel.

It is not easy to find information on the recommended type of fuel from Hyundai. The operating manuals are not presented for all models, but even those that are, sometimes do not contain the necessary data. So, there is no information on the required fuel for Creta in the manual - but there is data, for example, for Elantra and i 30. Recommendations differ depending on the country of operation: in Europe, you need to refuel with 95, and outside Europe, to achieve optimal performance, it is enough to use unleaded gasoline with an octane number RON (research method) 91 / anti-knock index AKI 87 - in other words, our 92nd.

Compatriots from Kia are a little more open about what to "feed" their cars: for the Rio, the official website exhaustively lists "unleaded gasoline with an octane rating of at least 92". For other models like cee’d, Optima, Sportage, Venga, and so on, you need to get to the owner's manual to see the same data as Hyundai.

In the photo: Kia Rio "2016 – present.

Budget segment

We say "budget segment" - we mean "Lada": the domestic manufacturer is confidently leading in terms of sales. He is equally confident in specifying fuel requirements in the technical characteristics of his vehicles. The only "disappointment", perhaps, is that the most budgetary models do not use the most budgetary gasoline: Granta and Kalina, and at the same time 4x 4, need at least 95th. But with Vesta and Xray, the situation is the opposite: both new products from the Volga Automobile Plant are happy to accept the "cheap diet". The situation with Largus is twofold: with an eight-valve engine with 87 hp. he is content with AI-92, but a more powerful sixteen-valve unit with 102 hp. already requires AI-95. It is also curious that on Granta the same 87-horsepower engine, as we remember, consumes 95th gasoline, while in Largus it is reconfigured to 92nd.

In the photo: Lada XRAY "2015 – present.

Another budget carmaker that is keen on reducing the cost of ownership of its products is Ravon. There are no reservations at all here: any of the Uzbek cars of overseas origin from R2 to Gentra is ready to eat AI-92 all its life and not show any signs of dissatisfaction.

There are "exceptions to the rule 95" and some Chinese manufacturers - for example, Lifan. So, the new Solano companions run on 95th gasoline, but the far from new Smily, together with Cebrium, is quite satisfied with the 92nd.

In the photo: Lifan 720 "2013 – present.

Well, the logical "final chord" of the list is the products of the Ulyanovsk Automobile Plant. It would be very strange to see 95th gasoline in the requirements for the content of the "veteran" Hunter - and, of course, it is not there. It is also absent in the specifications for the rest of the SUVs: all UAZ gasoline products work successfully on the AI-92.

Summing up

Taking a look at the list, it is easy to conclude that new cars capable of digesting 92nd gasoline are by no means the majority on the market. Nevertheless, there are also plenty to choose from: if you drive a lot and are careful about the choice of fuel, perhaps we made the task of finding a new car a little easier for you. In addition, it is worth remembering that forums dedicated to absolutely any brand are abundantly dotted with topics like "92 or 95", "Liu 92 and everything is fine", "Liu 92, I regularly change candles / catalysts / pistons and I'm fine" and so on. ... Hot discussions that "there is no 95th in Russia - it's all 92nd with additives!" do not subside for a second, and therefore the final choice of the liquid poured into the tank, as always, remains with the owner.

The main difference between 92 and 95 gasoline lies in their method of obtaining. Gasoline is a traditional fuel used for road transport. This is the fraction that is obtained by the distillation of oil. Regulatory documents and requirements of standards define several groups of manufactured motor gasoline:

• 80th - "normal".
• 92nd - "regular".
• 95th - "premium".
• 98th - "super".

In the designation of the brand of gasoline, the numbers indicate information about the value of the octane number. This parameter is responsible for the state of fuel stability, which determines the amount of its detonation. This means that the increased octane number of the fuel guarantees increased stability of its molecular structure, and reduces the level of detonation of gasoline. Knock refers to self-ignition when compressed in the engine's combustion chamber, which causes the gasoline to explode in the cylinder.

During a possible detonation of gasoline, the piston group and other engine mechanisms operate under critical loads, leading to rapid wear of parts. Currently, filling stations have a whole range of brands of gasoline, but the most popular and widely used are AI-95, 92 and 98 gasolines. determination of the octane number - a research method.

It is quite possible that if the octane number of the fuel is higher, then its cost for the end user is correspondingly higher.

Manufacturing technology

New technologies are promoting three methods of making fuel for automotive engines:

1. Obtaining a combustible mixture using direct oil refining, the octane number is equal to 50 units. This mixture has increased flammability and is not used in production. It requires adjusting the composition in special industrial laboratories with the requirement to increase the octane number.
2. Catalytic cracking is the most economical and simplest method for re-distilling gasoline to increase the octane number to 80. Catalytic cracking is used in virtually all fuel production plants.
3. Catalytic reforming is a costly from the point of view of economics, requiring high-tech equipment, a way to increase the octane number, but making it possible to reach the octane number up to 99. This method is usually used in European countries.

In special laboratories, gasoline, which has a low octane number, is a product of direct oil refining. By adding special additives, the composition of gasoline is adjusted, and the octane number is increased to the required level for the consumer.

Methods and uses of additives

• Fuel mixing... It is a technology method of mixing fuel with a chemical that has increased resistance to ignition. A chemical with a high octane number in excess of 250 units, which is called monomethylaniline, is successfully used here.
• Metal-containing additives... Tetraethyl lead became the main element of such additives. Such an element of additives creates the full return of gasoline of a given power and the greatest work of the engine of your car. The main disadvantage of this fuel is lead deposits on the walls of the combustion chamber. Over time, this negatively affects the respiratory organs of a person.
• Today use tetraethyl lead, as a fuel additive, was banned, and is no longer used even abroad.
• Use of alcohols and ethers... The simplest way to increase the octane number, which is used by many manufacturers of motor gasoline. The main feature of this method is the mixing of low grade fuel with essential substances. At the state level, the content of these alcohol-containing substances is limited to 15%, because a large concentration of additives with esters acts aggressively on rubber parts.

Gasoline AI-92

According to its quality parameters, it belongs to the "regular" type, like a fuel with a high octane number, and is adapted to function in carburetor internal combustion engines. The operation of carburetor motors has a peculiarity in that they operate at a high compression ratio. Gasoline of the AI-92 brand guarantees detonation resistance and stable operation of automobile engines. This fuel is gradually phasing out its activities in European countries, and its production has been stopped.

In our country, AI-92 fuel is the most common brand of gasoline, and it can be produced unleaded and leaded in a composition with additives that prevent detonation.

Gasoline AI-95

According to its parameters, this fuel belongs to the "premium" type, and is of the highest quality. For its manufacture, raw materials are used in the form of gasoline produced by catalytic cracking with the addition of aromatic and isoparaffinic additives, as well as gas fuel. There are sufficient anti-knock additives. The presence of lead in AI-95 has a limit of 0.013 grams per liter.

"Extra" motor gasoline is similar to standard AI-95 gasoline, but it does not have lead substances.

The main difference between 92 and 95 fuels

It is impossible to give one answer at once, which brand of fuel from the considered gasoline works best in engines. In this case, you need to know that the main parameter for assessing the quality of fuel is the value of the volume of substances containing alcohol and added to the main fuel mixture.

The content of substances with alcohol AI-95 gasoline is several units higher than AI-92 gasoline. This difference is very small that the driver will not be able to notice a significant difference in engine operation. Therefore, it is not scary if you pour 92 - AI-95 instead of gasoline. in fuel, the main thing is its quality. With good quality, the motor will not be damaged. Naturally, there is a difference in cost. AI-92 gasoline has always cost less than AI-95 fuel.

Can I mix gasoline 92 and 95

It is impractical to mix these gasolines as they cannot mix completely. Gasoline 92 will settle to the bottom, and 95 will rise to the top, but if the car is to run on 92 gasoline, then 95 can be used, this will even increase the engine speed and throttle response.

For new engines equipped with knock sensors, the replacement of gasoline from 95 to 92 is quite comfortable. When knocking occurs, the sensor signals to the electronic unit about the need to correct the operation of the motor, making the detonation minimum.

Many car owners believe that it is necessary to strictly follow the vehicle manufacturer's recommendations for the use of a particular brand of gasoline. Violation of these requirements often leads to expensive repairs. For example, the manufacturer specifies that the engine should run on 95 gasoline, and the owner of the car fills 92 gasoline, or a mixture of two gasolines. In this case, a problem with the engine will soon appear.

This is because the higher the octane number, the lower the combustion temperature. And when burning gasoline with low octane, the temperature will exceed the norm, some engine parts may burn out.

Which gasoline is better than 92 or 95? How to refuel your car? 4.50 /5 (90.00%) 2 vote (s)

Which gasoline is better than 92 or 95? Which one should you choose? This question is asked by all car owners. In theory, it is necessary to fill in what the automakers advise. In practice, the situation is slightly different. In this, we will consider both sides.

What is 92, 95?

What do these numbers mean? They mean fuel octane... The value describes the knock resistance of the fuel, i.e. the ability of the fuel to resist self-ignition during compression. Thus, with a high octane number, the likelihood of spontaneous combustion during compression is reduced.

In the production of fuel, the octane number, the purest, comes out in the region of 80-85. To bring it to the required level, it is mixed with various additives.

Gasoline compression ratio.

In order to determine which gasoline is better than 92 or 95, you need to understand what is compression ratio, what it is, and what it is for your engine.

Now, automakers are "chasing" power, with a small volume to make the engine as powerful as possible. How do they do it? Increasing the compression ratio will slightly increase engine power and lower fuel consumption. As a result, we get a powerful and economical engine. However, it is impossible to infinitely increase the compression ratio - it leads to spontaneous combustion of the fuel.

Compression ratio for engines:

1. If the compression ratio of the engine up to 10.5, then it is recommended to fill in 92nd gasoline.
2. If the compression ratio from 10.5 to 12, then it is recommended to pour 95th gasoline.
3. At above 12, then you need to fill in 98th gasoline.

What gasoline is better for refueling 92 or 95

From a technical point of view

If you pour 92nd gasoline into an engine rated for 95th. In which the compression ratio is higher and, accordingly, the 92nd will ignite from the compression ratio of the engine. Those. the motor will detonate. Accordingly, it will show detonation (explosive combustion of fuel)... This process, inherently, can harm the engine. After all, the fuel in must ignite precisely from the spark plug. Those. ignition occurs a little earlier than the piston reaches the high point, compressing the fuel. And at the 92nd it happens a bit earlier.

You can now think that your engine is designed for the 95th, and you pour 92 and nothing happens. In addition, the quality of the fuel, especially in the Russian realities, leaves much to be desired. After all, everyone can get into such a situation that when they arrive at a gas station, they fill it with 95, but in fact, this fuel has an octane number of 90. In this case, in theory, the engine should detonate strongly and almost collapse.

Car manufacturers took this fact into account. And so it is in modern cars. Located on the engine and reads vibration. As soon as the engine starts to vibrate the wrong way. The sensor begins to transmit electrical impulses to the ECU unit. If these impulses exceed some norms, then the unit decides to adjust the ignition timing and the quality of the supplied fuel mixture. Making her rich or poor.

Filling a motor designed for 95, 92nd gasoline, respectively, this is a lean mixture, detonation occurs, etc. Further automation, the ECU reconfigures all this and, in essence, Can't even feel the difference.

Thus, we can conclude that the engine is on 92 gasoline, will work no worse than 95... However, at high speeds, in the range of 6-7 thousand rpm, the sensor will not work so correctly. Therefore, we do not recommend “pressing on the floor” on low-octane fuel, this will have a destructive effect on the engine.

Because the consequences may not be very good:

1. Early detonation of fuel.
2. Damage to cylinder walls and pistons.
3. Accelerated engine wear.
4. Overheating of the engine.

Due to the fact that the air-fuel mixture does not completely burn out, carbon deposits begin to accumulate on the cylinder walls. As a result, this leads to a decrease in engine power, a drop in compression, and an increase in fuel consumption. All this leads to premature wear of the piston rings and damage to the cylinder walls. Which will soon lead to necessity.

But this is all ideally, from a technical point of view. Those. what kind of gasoline the car is designed for, this is what you need to pour.

What is the reality?

Driving into a gas station, are you sure that when you buy 95, you are getting exactly 95, with this octane number? Are you sure of the honesty of this filling? How can this be verified? Unfortunately, no way.

So, what will happen if instead of 95 you pour 92nd gasoline? A question that torments many. So, if you prefer a quiet ride, do not press "on the floor" on your car, then you can safely fill in 92nd gasoline. Nothing bad can happen to your engine. But on condition of a calm and moderate drive. After all it all depends on driving style.

That is why, for active driving, automakers recommend filling in fuel with the octane rating that is intended for this engine.

For turbo engines, the compression ratio of the engine is not important. Therefore, it is recommended to fill the 95th.

However, do not forget that the cost of the 92nd is lower than the 95th. "Why overpay when there is no difference?" - many car owners think and say so. There is a difference, but if you are a thrifty person, and you are sure for sure that high-quality gasoline 92 is sold at your gas station, with just such an octane number, then feel free to refuel.

The reality is that once you fill in fuel with a lower octane number, you will not be able to disable it immediately, but with such constant savings, you will, of course, spend money on expensive repairs.

What happens if instead of 92 you pour 95?

If you fill the engine designed for 92, 95th gasoline, then nothing bad will be, rather better. Those. the engine will run smoother. It is necessary to understand that if you fill in fuel with better characteristics, then it is even better for the engine. Those. detonation is practically excluded altogether, respectively, the fuel will ignite precisely from the spark plug, and not from the compression ratio.

Therefore, filling in fuel with a higher octane number, the engine will be a little better, a little smoother to work. Those. more octane needs a higher temperature and compression ratio... Thus, such fuel burns longer and generates more heat. But do not expect a large surge of power from it, or a decrease in consumption, you will not feel it.

In conclusion…

Now you know which gasoline is better than 92 or 95, and which one is better to fill. Therefore, if the engine supports fuel with an octane rating of 92 and higher, then pouring AI-92 or AI-95 is already everyone's business.

At the moment, most motors are optimized for the 92nd.

It's another matter if a more modern car, and tolerances from 95 and higher. In such a situation, an attempt to save on 92 gasoline may cost a major overhaul. And is it worth saving then?

Owners of cars with gasoline engines are often interested in which gasoline is better, choosing between the brands of fuel sold at gas stations. This formulation of the question is by no means rhetorical, but has a completely practical meaning. This is due to the settings of the power unit, the stable and predictable operation of all related systems, as well as the financial question: to pay more or not to pay? Let's understand the essence of the issue.

The numbers indicated when marking the fuel indicate very specific indicators and indicate the octane number. The higher it is, the more the fuel can resist spontaneous ignition during the compression stroke in the engine cylinders. This helps to reduce the likelihood of knocking when the engine is running. Detonations mean accelerated uncontrolled combustion of the fuel mixture, in fact an explosion.

Gasoline selection

You need to know that the octane number is used only for gasoline, and for diesel grades of fuel, the "cetane number" is involved in the characteristics.

Determining the cetane number is significantly different from identifying the octane number.

Gasoline distributed through the retail network may now have a maximum octane rating - A 98. But to find out what is better to fill 92 or 95 into the tank of a particular car, you will need to consult the manufacturer.

Carmakers can recommend both a specific type of fuel and a range of acceptable values. You can find out this parameter in the instructions that come with new cars or get information on the manufacturer's website. Often, for quick access to such data, the exact permitted numbers for gasoline are indicated on the inside of the gas tank cap.

If it is necessary to select one brand, then there will be a designation, for example, RON 92, and when a range is allowed, then it is RON +95 or RON 92-95.

The injection engines installed on the car are designed for a specific brand of fuel. Here, the manufacturer's recommendations will be unambiguous. Fulfilling this requirement, the driver will protect the engine, fuel system, catalyst and extend its service life for the entire car.

Legend on the gas tank cap

Fuel modifications and manipulations

Additives can be used to change the parameters of the fuel. With their help, it is possible to artificially increase the octane number. Traditionally in our country all additives (legal and not) that are added to technical fluids are called additives. Counterfeit products (often useless and sometimes harmful) have discredited the term.

The difference between 95 gasoline and 92 gasoline lies in the fact that the A92 brand is the "purest" product is a delusion. Some unscrupulous sellers often get higher octane numbers due to chemical impurities, octane correctors. Proving the opposite can only be done by laboratory testing.

The "octane number boosters" that have flooded the market do not always correspond to the declared characteristics.

Although, judging by the application, they should increase power, reduce consumption and reduce the detonation properties of gasoline.

There are situations when a car will not be able to drive without additives. This happens when filling low-quality gasoline. This is determined by the decrease in power and the emerging extraneous sounds from the engine compartment. At the same time, additives from a trusted manufacturer can save the day.

Adding fuel additives

The main enemy of high-quality gasoline is sulfur content.

It is capable of slowly corroding the fuel system like caries. But there are no additives on the market that reduce its level in gasoline. Therefore, filling in the "relaxed" mixture "pseudo A95", the motorist risks more than when refueling with a high-quality A92.

Marketing A95

Recently, it is easy to find a product at a gas station with a Premium or Eco attachment. They are offered at a higher price. This is justified by the presence of substances that help to clean the fuel system, as well as to obtain an increased power of about 10%. The latter is hardly worth hoping for.

There is an opinion that additives that help clean the injector and valves from carbon deposits behave too aggressively and lead to rapid wear of mechanisms and assemblies.

In reality, the percentage of such additives is small. Therefore, fuel with these components can be periodically poured into the tank.

Maximum 98th

Gasoline with this octane rating should only be used in sports engines. It is designed for high-tech power plants with a protective coating on the piston group.

For cars not adapted to high-octane fuel, there can be disastrous consequences for the engine. When working with it, local overheating often occurs, which enhances the deformation of the metal. The valve also burns out more actively. Unsuitable candles ignite the mixture ahead of time, so the flame spreads faster than usual.

Basic safety measures at gas stations

Refueling at stations bearing the logo of a popular brand is not always a guarantee of high-quality gasoline. Oil companies usually resell franchises (trademark rights) to smaller companies. There are frequent cases of renting out small networks of gas stations. And in the terms of the lease, lists of mandatory suppliers are not always spelled out.

You can visually distinguish rented stations from native, branded ones sometimes by the presence of additional store chains on the territory of the gas station.

Also, a virtual map showing the points of branded gas stations will be of help. It can be found on the oil company's website.

If possible, then you should limit yourself to visiting only proven stations. Thus, the risk of getting low-quality fuel will be reduced. At unknown points, it is advisable to fill only a limited minimum.
