At present, 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 their own transport is more reliable, more opportunity to be in time everywhere. There are many brands of cars, and the gasoline they run on must match the specific model. Today, AI-92, AI-95 gasoline brands are more popular. Which one is better for domestic car Lada Priora?
Automotive fuel
Gasoline is a mixture of hydrocarbons that has the following properties:
- flammable;
- mostly colorless;
- density 700-780 kg/m2;
- highly volatile and flashes at 20-40 ° C;
- boils at 30-200°C;
- freezes at -60°C.
To improve the quality of the fuel, additives are added in the amount of 0.07-0.2%:
- Antiknock agents (monomethylaniline 15%).
- Antioxidants.
- Anti-corrosion agents for metals.
These additives are poisonous, environmentally hazardous and give high temperature when burned, which can damage the engine of the machine.
It is best to use methyl carbinol and dimethyl ketone when necessary, 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 oil, it has two main specifications marked with letters and numbers:
- A is motor.
- Mark AI - research.
- Numbers 92, 95 - percentage of isooctane with heptane.
- The octane number characterizes the resistance of gasoline to detonation. The higher the percentage, the lower the probability of failure of the cylinder-piston group of parts.
- Detonation - arbitrary self-ignition of gasoline from pressure with consequences in the form of an explosion.
AI-92:
- used for work carburetor engines internal combustion;
detonation resistant; - ensures stable operation of the engine;
- has wide popularity in Russia and the CIS countries;
- summer is used in the southern regions Russian Federation throughout the year, and in the northern ones - 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;
- well and long stored;
- quickly burns out and evaporates during mining.
Chemical composition:
- contains sulfur - no more than 0.05%;
- there is manganese - in 1 dm³ - 18 mg;
- resin composition per 100 cm³ - up to 5 mg;
- etiolation is possible (0.15 g/l Pb);
- without etiolation (0.013 g/l);
- can boil at 33-205 ° C;
- benzene is present no more than 5%;
- p at 15 °С kg/ - 725-780;
- transparent liquid.
AI-95:
- Expensive.
- Less gasoline consumption by 3-4%.
- 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 big violation if, in an unusual situation, instead of one gasoline, fill in another, but it must be borne in mind that in the event of a breakdown vehicle this will affect the warranty. Especially if AI-92 is used after AI-95. You shouldn't mix at all, because chemical composition they are still different, and the mixture will not work. To increase the life of the machine's engine, it is better to use the brand recommended by the instruction. And be sure to keep receipts after refueling to provide them to the service station and when checked by specialists exhaust system cars.
LADA PRIORA 8-valve:
- power - 90 horsepower;
- speed acceleration - up to 176 km / h;
- fuel consumption is approximately 6.2-8.8 liters per 100 kilometers;
- cheaper repair and maintenance;
- simpler engine design;
- semi-synthetic oils are used;
- quite suitable for AI-95;
- minus in noisy operation and low motor power;
- discontinued due to obsolescence of the model.
In the car's passport it is noted that she works on the AI-92. According to the reviews of the owners and testers, the following picture is obtained:
- Alexander Stefantsov, 45 years old, driving experience - 20 years: “I decided to boo, filled AI-95, started up faster, purred calmly, accelerated harder, drove in order, but then I noticed a knock. I went to the service station: it is necessary to change the pistons, it was not the right gasoline.
- Sergey Paramonov, 30 years old, driving experience - 10 years: “Everything is fine, the gasoline is excellent, but you will arrive for repairs earlier than it should be under the guarantee, and they won’t 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 the 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 the highest speed;
- 5.6-9.8 liters per 100 kilometers of fuel is needed;
- smooth and silent operation of the motor;
- fuel only AI-95;
- tank volume - 43 liters;
- runs on expensive synthetic oils;
- more expensive than a service station;
- a newer and more modern machine.
Pour gasoline into 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, driving experience - 8 years: “Friends said that the AI-92 is no worse, cheaper, so I traveled. Firstly, the consumption increased, and secondly, I had to change the candles.
- Andrey Kuznetsov, driving for 5 years: “I have little experience, I listened to what others would say, and then in fact it was necessary to change the converter, that’s the savings.”
92 grade gasoline fouls the engine and spark plugs faster. The vehicle clearly responds 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 the correct choice depends on how quickly you can get to overhaul. The problem of good auto fuel due to high demand rests on the quality of its processing and the cost, which is constantly rising.
Unscrupulous suppliers take advantage of the urgent need for gasoline and drive fakes with various mixtures that destroy car parts. A great influence on the smooth operation of equipment will have right choice Gas station with good quality petrol.
The car has entered our lives forever. At present, it is no longer a luxury, but a necessary means of transportation.

Look at the table - all the presented cars are equipped with engines manufactured by the Volga Automobile Plant. The source of the fuel data given is the latest instruction manuals.
There are many questions. For example, why is the 16-valve K4M engine developed by the alliance under the hood Lada Largus requires AI-95, but in Almere, Logan and Sandero 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 grade in Russia, but a low-quality 92nd can get into the tank, with which the motor can somehow cope.
The situation is no better with domestically developed motors. 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. Electronic system management within reason will cope with a lower octane number. Read - regrading, if instead of the 95th the crooks fill in the 92nd, nothing will happen to the motor. Allow officially the 92nd, and a mixture of 92 with 76th can get into the tank instead, 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 Prior, Kalina and Grant under the VAZ-21127 index, only AI-95. Or, say, the eight-valve VAZ-11189 for Largus officially swallows the 92nd, and give the same Kalina VAZ-11186 engine only the 95th. There is also a mess with the wording: for technically identical Lada and Datsun, in one case it is allowed, in the other it is recommended.
Moreover, the picture has developed a curious - more expensive cars cheaper gasoline is allowed, but give the most popular more expensive. Nonsense? Undoubtedly!
Does anyone seriously believe that the owners cheap cars domestic production 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 Lada 4x4 and Chevrolet Niva they cannot live without the 95th, and the eight-valve descendants of the reliable "eight" engine will begin to break down on the 92nd? But the consumer understands perfectly well - with an average annual mileage of 12 thousand km and a difference in fuel prices of three rubles per liter, on the 95th he will fly out to exhaust pipe at least three thousand rubles more.
