Which gas is better to fill?

The importance of gasoline throughout the world is quite obvious. As a person can not live without blood, the economy of any country will collapse and simply cease to develop. Every year, billions of gallons of this necessary liquid are consumed in the world. The composition of gasoline includes only molecules of carbon and oxygen, which are connected by chains. In each chain there may be about 7-11 carbons. Gasoline is produced from crude black oil extracted from the earth. Owners of cars, especially beginners, constantly tormented by the question of which gasoline is better to fill. To do this, consider what kinds of gasoline there are.

Types of gasoline

There are several types of gasoline thatdiffer from each other in detonation properties. Detonation is the process of rapid combustion of a working fluid in the chamber, resulting in the formation of shock waves. If the driver heard a characteristic sharp knock - then, the process of detonation of the engine occurred. The detonation resistance of gasoline depends on the octane number. Depending on the percentage of isooctane, it becomes clear on which gasoline it is better to drive. The higher the percentage of isooctane, the higher the detonation resistance.

Gasolines containing a high percentage of octane cancan be obtained by two methods: by increasing the high-octane components in the production process and by adding tetraethyl lead to the gasoline. The first way is more complicated, the second way is more simple and cheaper. In the first case, unleaded gasoline is produced, in the second case - leaded gasoline. Tetraethyl lead enhances the detonation resistance of gasoline. In the CIS countries today produce the following types of gasoline:

  • A-72.
  • A-76.
  • A-80.
  • AI-91.
  • AI-92.
  • AI-93.
  • AI-95.
  • AI-98.

Gasoline can be: leaded, unleaded, unleaded. They are also available for use in summer and winter time periods.

Ethylated gasolines are colored in different colors. For example, the A-72 has a pink color, the A-76 is painted yellow, the AI-93 has a red-orange hue, the AI-98 is tinted in blue. Abroad, in general, premium gasoline is used, which belongs to the first grade, it has an octane number of 98-98 and petrol of the brand "Regulator" - it belongs to the second grade and has an octane number of 90-94. Some countries produce "Super" gasoline, the octane number of which is 99-102. If the car is of foreign manufacture, it is better to use gasoline with an octane number of 91-92, for models of the 90-ies release gasoline should contain octane number not less than 94.

Unfortunately, at different gas stationsthe quality of gasoline is different. Therefore, it is better to refuel your car on proven gas stations, and it is desirable that there is one and the same dealer. Many drivers are trying to figure out which gasoline is better in winter, but paradoxically, some prefer to refuel their tank with 92 gasoline, others - 95. In winter it often depends on the type of gasoline whether a car can start. Some drivers do not see a tangible difference between the brands of gasoline 92 and 95. But, of course, of course, should win gasoline A-95. Specialists recommend the use of AI-95 gasoline in winter, especially for those cars that "spend the night" under the open sky.

Force Majeure on the Road

Sometimes on the road this situation may arise,at which to the nearest settlement there were several kilometers left, and gasoline ended. In this case, it is reasonable to ask, and what to fill in instead of gasoline? For information of skeptics, the car is able to ride on everything that burns, even if the tank is filled with alcohol, and the higher its degree, the better.

Of alcohol, the most suitable fuel is pure medical alcohol or vodka, but it must first be evaporated. Methyl and ethyl alcohols can also be used as a fuel.

A great option for refueling a car tankthere will be kerosene, which will allow the car to accelerate. Butane and propane can also be used in the form of fuel. Do not forget that after the replacement of gasoline by other combustible, the car may need repairs.

Now you know all about how to choose the right gasoline! We wish you good luck on the road!
