The car entered our life forever. Nowadays it is no longer a luxury, but a necessary means of transportation. The age of speed has come, everyone needs to hurry: to work, to study, to rest, on various important matters, and to have your own transport is safer, there is more opportunity to be in time everywhere. There are many brands of cars, and the gasoline they use must match a specific model. Today, the more popular brands of gasoline AI-92, AI-95. Which is better for the domestic car Lada Priora?
Automotive fuel
Gasoline is a mixture of hydrocarbons with the following properties:
- flammable;
- mostly colorless;
- density 700-780 kg / m 2;
- highly volatile and flashes at 20-40 ° C;
- boils at 30-200 ° C;
- freezes at -60 ° C.
To improve the quality, additives are added to the fuel fuel in the amount of 0.07-0.2%:
- Antiknock agents (monomethylaniline 15%).
- Antioxidants.
- Metal corrosion products.
These additives are poisonous, environmentally hazardous and give a high temperature during combustion, which can damage the engine of the machine.
It is best to use methylcarbinol and dimethylketone when needed, as they are less toxic. If you add one hundred milliliters of ethanol to one liter of AI-92 fuel, you get AI-95, since the octane number increases.
Gasoline is obtained from petroleum and has two main technical characteristics, indicated by letters and numbers:
- A - motor.
- AI brand - research.
- The numbers 92, 95 are the percentage of isooctane with heptane.
- The octane number characterizes the detonation resistance of gasoline. The higher the percentage, the lower the probability of breakage of the cylinder-piston group of parts.
- Detonation is the arbitrary self-ignition of gasoline from pressure with consequences in the form of an explosion.
- used for the operation of carburetor internal combustion engines;
- detonation resistant;
- ensures stable engine operation;
- has wide popularity in Russia and the CIS countries;
- summer is used in the southern regions of the Russian Federation throughout the year, and in the northern - from 01.04 to 01.10;
- winter - in the north of the country from 01.10 to 01.04;
- 4th class according to the EURO-4 standard;
- works from +60 to -35-55 ° С;
- good and long-term storage;
- quickly burns out and evaporates during development.
Chemical composition:
- contains sulfur - not more than 0.05%;
- there is manganese - in 1 dm³ - 18 mg;
- resin composition per 100 cm³ - up to 5 mg;
- etiolation possible (0.15 g / l Pb);
- without etiolation (0.013 g / l);
- can boil at 33 - 205 ° C;
- benzene is not more than 5%;
- p at 15 ° C kg / - 725-780;
- clear liquid.
- Dear.
- Less gasoline consumption by 3-4%.
- High quality: the car starts faster and the speed is higher.
- More resistant to detonation due to the increased alcohol content.
Chemical characteristics:
- less lead - 0.010 g / l;
- manganese - 18;
- resins - 5.0;
- S - no more than 0.05%;
- benzene - 5%;
- density - 725-780.
There will be no major violation if, in a non-standard situation, instead of one gasoline, pour another, but it must be borne in mind that if the vehicle breaks down, this will affect the warranty. Especially if AI-92 is used after the AI-95. It is not worth mixing at all, since they are still different in chemical composition, and the mixture will not work. To increase the service life of the machine engine, it is better to use the brand recommended by the instruction. And it is imperative to keep receipts after refueling in order to present them to the service station and when checked by the specialists of the exhaust system of the car.
LADA PRIORA 8-valve:
- power - 90 horsepower;
- acceleration of speed - up to 176 km / h;
- fuel consumption is approximately 6.2-8.8 liters per section of 100 kilometers;
- cheaper repair and maintenance;
- simpler engine design;
- semi-synthetic oils are used;
- quite suitable for AI-95;
- minus in noisy work and low motor power;
- discontinued due to obsolescence of the model.
In the passport of the car it is noted that it works on the AI-92. According to the owners and testers, the following picture is obtained:
- Alexander Stefantsov, 45 years old, driving experience - 20 years: “I decided to boo, filled the AI-95, started up faster, quietly purred, gassed harder, drove in order, but then I noticed a knock. I went to the service station: it is necessary to change the pistons, the gasoline was not the right one. "
- Sergey Paramonov, 30 years old, driving experience - 10 years: "Everything is fine, the gasoline is excellent, but you will arrive for the repair earlier than it should be under warranty, and they will not turn it on because of the AI-95".
Gasoline of this brand burns faster, and the temperature is higher, therefore, gradually and imperceptibly, but harm is done to the combustion chamber, which is not designed for such power. The conclusion follows: use fuel according to the instructions, and there will be fewer problems.
Car LADA PRIORA 16-valve, 2013-2014:
- 106-123 horsepower;
- 183-190 km / h highest speed;
- 5.6-9.8 liters per 100 kilometers you need fuel;
- smooth and quiet operation of the motor;
- fuel only AI-95;
- tank volume - 43 liters;
- works on expensive synthetic oils;
- more expensive than service station;
- newer and more modern car.
The car of the latest release is equipped with a large number of electronic systems that require respect and high grade gasoline.
But I want to save money, and here are vivid examples:
- Anatoly Samoilov, 35 years old, driver's experience - 8 years: “Friends said that AI-92 is not worse, cheaper, so I traveled. Firstly, the consumption increased, and secondly, the candles had to be changed. "
- Andrey Kuznetsov, driving for 5 years: “The experience is small, I listened to what others would say, and then, in fact, it was necessary to change the neutralizer, that’s the savings”.

Pour gasoline into the Lada Priora The latest release car is equipped with a large number of electronic systems that require careful handling and high grade gasoline.
But I want to save money, and here are vivid examples:
- Anatoly Samoilov, 35 years old, driver's experience - 8 years: “Friends said that AI-92 is not worse, cheaper, so I traveled. Firstly, the consumption increased, and secondly, the candles had to be changed. "

Gasoline 92 tends to contaminate the engine and spark plugs faster. The vehicle clearly reacts to all changes, and this is shown by the instrument panel. The brand of gasoline and the type of engine are directly related to each other, and how quickly you can get to the overhaul depends on the right choice. The problem of good auto fuel due to high demand rests on the quality of its processing and the cost, which is constantly increasing.
Unscrupulous suppliers take advantage of the hype for gasoline and drive fakes with various mixtures that destroy car parts. The correct choice of gas stations, where high-quality gasoline is available, will have a great impact on the smooth operation of equipment.
Look at the table - all presented cars are equipped with engines produced by the Volga Automobile Plant. The source of the given fuel data is the latest operating manuals.
There are many questions. For example, why does the 16-valve K4M engine developed by the alliance under the hood of Lada Largus require AI-95, while in Almera, Logan and Sandero it can work on AI-91? Moreover, Renault even allows short-term operation on gasoline with an octane rating of 87 according to the research method. There is no such variety in Russia, but a low-quality 92nd can get into the tank, with which the motor can at least cope with it.
The situation with domestically developed motors is no better. Not so long ago, VAZ had a unified technical policy - it was allowed to use "only unleaded gasoline with an octane rating of at least 95". This position of engine developers is justified. It is difficult to accept, but understandable. Indeed, the best indicators of efficiency, environmental friendliness and throttle response are achieved with high-octane fuel. Plus the manufacturer's insurance against low-quality fuel in the regions. The electronic control system will cope within reason with the lowered octane number. Read it - it's a mess, if, instead of the 95th, the crooks flood the 92nd - nothing will happen to the engine. Officially permit the 92nd, and instead of it, a mixture of 92 and 76 can get into the tank, and this is already fraught.
But new generation cars have appeared, and what do we see? For Vesta and XRAY with a VAZ-21129 engine, AI-92 is allowed, and for similar engines on Priora, Kalina and Grant under the VAZ-21127 index, only AI-95 is allowed. Or, say, an eight-valve VAZ-11189 for Largus officially swallows the 92nd, and give the same Kalina VAZ-11186 motor only the 95th. With the wording, too, leapfrog: for technically identical Lada and Datsun, in one case it is allowed, in the other - it is recommended.
Moreover, the picture is curious - more expensive cars are allowed cheaper gasoline, and the most popular cars are more expensive. Nonsense? Certainly!
Does anyone seriously believe that the owners of inexpensive domestically produced cars blindly follow the instructions? Okay, more or less fresh 16-valve engines: here you can hide behind an argument - they were designed for high-octane fuel. But how to convince the owners that the dense engines of the classic family for the Lada 4x4 and Chevrolet Niva cannot live without the 95, and the eight-valve descendants of the reliable eight-cylinder engine will start to break down on the 92? But the consumer understands very well - with an average annual mileage of 12 thousand km and a difference in the price of fuel of three rubles per liter, at the 95th it will fly into the exhaust pipe at least three thousand rubles more.
