Each owner of the car collides with fuel of the standard EURO-4 or gasoline EURO-5. What does this mean and what are the differences between the standards? We will try to deal with these issues.
Environmental European standards
For all types of diesel and gasoline inIn 1992 the European environmental standard was adopted. According to this standard, fuel is classified depending on the content of impurities and harmful substances in it, which adversely affect the environment.
There are different fuel standards:EURO-5, EURO-6, EURO-4, EURO-3, EURO-2, EURO-1. Many countries allow the sale of only such new cars that support the EURO-5 or higher standard, that is, the class of consumed fuel should be at least EURO-5.
Differences between gasoline EURO-4, EURO-5
At the moment, most filling stationssell fuel EURO-5 or EURO-4, but gasoline of the sixth standard is extremely rare. As for the fuel of earlier standards, it is nowhere in the world for sale.
The difference between gasoline of the fourth and fifthstandards is and consists in the content in the fuel of heavy metals and impurities that increase the content of carbon monoxide and carbon dioxide, as well as nitrogen oxides in the exhaust gases when the engine is running. This means that the products of gasoline combustion standard EURO-5 will be less harmful to the environment.
Some countries fuel regulations regulatevery strictly. In Russia, unfortunately, this is being monitored, but not as rigorously as in Europe. There are differences between the types of fuel of the fourth and fifth standards, and this should be paid attention. Refueling at the gas station, drivers usually do not follow what fuel standard they fill. But it's easy to find out by looking at the documentation for fuel, which must necessarily be at the cashier.
In EURO-5 fuel, the sulfur content is lower bycompared with the fuel of the fourth generation, so better use it. Of course, a modern car (especially with a carburetor engine) will not immediately feel the difference from using cleaner gasoline, but after 20-30 kilometers of mileage the difference will be visible. Moreover, gasoline with a lower sulfur content does not exactly hurt any transport.
Note that the higher the fuel standard, the cleanerhe will. Cleanliness plays a large enough role and is important for normal and trouble-free operation of the engine. Due to the low sulfur content of gasoline, the service life of injectors, lines, and spark plugs is increasing. Also in the combustion chambers of carbon deposits, much less is formed.
The EURO-5 standard is more favorable forlambda probes of cars, exhaust systems and catalysts. As a result of using this type of fuel, the dynamic characteristics of the machine increase, the speed of acceleration increases, and the consumption decreases. Also, the operating instructions for the car must indicate the required octane number. Petrol EURO-5 has an increased octane number, and if the instruction clearly states the requirement to use fuel of this standard, then it is not necessary to pour another gas into the tank.
Often, car owners whose motorsdesigned to run on gasoline A-92, use gasoline 95. Then, during the technical inspection, the level of CO in the exhaust gas will be lower. This is logical, tk. the content of impurities and sulfur reduces the level of harmful substances.
If to generalize, the chemical compositions of these speciesfuel is not much different. Both are produced from oil. There is an opinion that the higher the octane number, the more pure it is. This is not so in fact. The octane number determines only the resistance of gasoline to detonation, but not its purity.
Some drivers are trying to find out whichoctane number of gasoline EURO-5. It can be different depending on what gasoline is used. For example, well-refined gasoline A-92 can refer to the EURO-5 standard. Its octane number is 92. At the same time, petrol 95 with octane number 95 can refer to the ecological standard EURO-4 due to the presence of various impurities.
Russian legislation permitsThe exploitation of cars that consume gasoline of both standards. Which class to choose is a personal matter for each driver. But the fact is the fact: the higher the fuel class, the better and safer.
Perhaps, now you understand that this is EURO-5 gasoline.
Differences of subspecies
Previously, everything was simple.The drivers did not particularly think about what kind of gasoline to pour into the tank. The gas stations offered gasoline A-76, A-92, A-95, A-98. But today almost at any gas station you can choose between ordinary gasoline and ... And then there are many different consoles such as "ecto", "plus", "paver", etc. Usually, drivers do not understand the difference between ecto gasoline from EURO-5, but the refuelers unanimously assert that the brand-name fuel is capable of washing the engine and even increasing its life. How true is this?
The usual EURO-5 petrol - what is it?
This is the most common gasoline that isat all gas stations in Russia. Such fuel meets the standards of EURO-4 or EURO-5. Previously, the fuel sold standards of EURO-2 and EURO-3, but it stopped selling long ago. This means that all gasoline at the gas stations is of high quality. True, this is only true if the gas stations adhere to the norms of the law.
Note that since January 2016 all new imported cars to the territory of the country must comply with the EURO-5 standard.
EURO-5 without additives
Russian producers can produce gasolinestandard EURO-5, which is actively used in Europe. In Ukraine, for example, there are no oil refineries capable of producing such fuel, so all gasoline is imported from Belarus, Romania, Poland, Lithuania. Its difference from the fuel of the standard EURO-4 - lower sulfur content and the lack of benzene. This does not affect the dynamics of the car, and fuel is consumed about the same way, but the process of carbon formation and aging of engine oil slows down. This is important enough for cars that were produced after 2005.
Fuel with detergent additive
Many branded gas stations try to give theirproducts a certain zest that would distinguish it from competitive. Therefore, some gas stations promise that their gasoline will be able to wash the engine from the inside, which will improve the engine. For this, detergent additives are used - they are simply added to gasoline. These additives include corrosion inhibitors, water scavengers and detergents. Is it worth buying such fuel? I think no. Often such gasoline is diluted with various chemicals directly in the gasoline tank truck. This is beneficial, because additives are cheaper than gasoline. This means that the more additives you add to the tanker, the more money you can earn.
As for the damage to the motor, it will most likely not be, but it will affect the consumption. In general, it is desirable to flush the engine in other ways, rather than additives in gasoline.
Mixture of alcohol and gasoline
The next type of fuel, which raises questions for car enthusiasts, is a mixture of gasoline and alcohol. Often such gasoline is sold as branded fuel. And it is even cheaper than usual for 2 rubles per liter on average.
You can fill up with such gas, but it's important here.Know what alcohol content is in the fuel. To do this, ask the seller for a passport of fuel, which indicates how much alcohol was added to the mixture. If the alcohol content does not exceed 10%, then this is good. Such fuel will have a high octane number, which will increase the efficiency of your engine. However, a large concentration of alcohol will be harmful: there will be deposits of fusel oil in the engine, and its work on idlers will be difficult.
Gasoline A-98 instead of A-95
Many drivers are mistaken when they think thatThe use of 98-th gasoline instead of the 95 recommended by the manufacturer will do good. It's a myth that at the same time fuel economy is 18-20%. This is true only for those cars, whose engines were originally designed for the standard EURO-6 and gasoline A-98. Otherwise, there will be no effect.
In addition, pour gasoline with increased octanenumber sometimes makes no sense, because this can damage the valves and rings. The latter can trite corn. For the same reason, do not recommend the use of various kinds of additives designed to increase the octane number of gasoline.
Is there any point to refuel with gasoline A-92?
Many drivers in order to save money incars gasoline A-92, although their car is designed for fuel A-95. Yes, they save 2-3 rubles per liter, although this economy is very doubtful. Doing this is not recommended for various reasons. At a minimum, fuel consumption for gasoline A-92 is 10-15% higher, therefore the money saved will go to the fast fueling of a new batch of fuel.
Also, such gasoline will have a loweroctane number, and in engines for which it is not intended, detonation will occur in the cylinders. This means that the fuel mixture will ignite too soon, and this will lead to an increased load on the engine. The motor in this case is subject to rapid wear. Therefore, there is no point in saving it.
Conclusion
Now you know that this is EURO-5 gasoline, and itskey differences from the fuel of other standards. It is intended for modern cars. In addition, the standards are constantly being improved. The standard EURO-6 in the form of gasoline A-98 is already actively sold at gas stations, though, so far, it is in less demand.
