Super gasoline or regular gasoline; This is a question that may come to some people when they enter the gas station, but what is really the difference between these two types of gasoline and how can they be distinguished?
Some people think that super gasoline is better than regular gasoline and improves the performance of the car, while others believe that the two are no different and just have different names. So here we introduce super and regular gasoline as well as the difference and how to distinguish this gasoline from each other, so we suggest you read the contents to the end.
What is gasoline?
Petrol; In German ( BenzinIs a fraction of oil that is distilled between 70 and 175 ° C and contains C hydrocarbons.5 to C11 or C12. Natural gasoline, which makes up about 15 percent of crude oil, is used in combustion engines. Ordinary gasoline is a collection of hydrocarbons such as kinds of paraffin (alkanes), naphthenes (cycloalkanes), and olefins (alkenes); But can be octane ( C۸H18) was considered one of the specific compounds in gasoline. This fuel was first called “gasoline” in Germany. Contrary to many people’s beliefs, the name Bertha Benz is derived from the name Bertha Benz(Which in 1888 bought the gasoline it needed to drive from Mannheim to Fortzheim from a drugstore), the name comes from the chemical benzene. In many countries and languages, it is also called gasoline or very similar to gasoline.
In most Commonwealth countries, with the exception of Canada, the term “petroleum” (meaning rock oil) is used. Gasoline (English: GasolineMainly used in North America, commonly used in the conversational uses of “Gas”.It is said that in terms of its application, it should be possible to completely differentiate it from gaseous fuels such as liquefied petroleum gas used in internal combustion engines. The word “gasoline” in British English refers to another oil derivative used in lamps, but it is not commonly used today.
The word “gasoline “) Was bitten in 1865. The current spelling of the word was first used in 1871. The abbreviated form of gas was first recorded in 1905 in English and America. Recorded by Kapel, Leonard, and Carles. Although not yet officially registered as a trademark, Carles’s competitors did not use the term Motor Spirit until 1930Used.
Introduction of Super Gasoline and its History
Super gasoline ( Premium gasOrdinary gasoline is said to have an additive added to increase its octane number. For the first time during World War I, a person named Migli realized that adding lead to gasoline could increase its octane number without much cost. After being aware of the toxicity and environmental damage of lead, methyl tert-butyl ether was substituted for lead. Later, they found that methyl tert-butyl ether also caused environmental pollution, so they sought alternatives to the substance, which included toluene, 2-methyl-2-propanol, and methyl-tributyl ether ( MTBE ).), Methanol and ethanol. In 1984, methyl tert-butyl ether was the most common additive.
The benefits of super gasoline
The fuel mixture used in car engines is flammable depending on the engine compression ratio. Particularly in engines with high compression ratios such as 1 to 12 (as opposed to older models with ratios of 1 to 5 or 6), this mixture may ignite in the compression stage before the spark plug ignites, creating a knocking state. This is considered an undesirable phenomenon due to reduced efficiency. To prevent this phenomenon, try to add special substances such as diethyl lead (obsolete), alcohols such as methanol and ethanol, and cyclic hydrocarbons such as toluene and xylene (due to reduced pollution), as fuel mixture. Increase the octane number of gasoline. These additives make gasoline burn more slowly. In Iran, the octane number of ordinary gasoline is about 87 and for super gasoline is about 94-95.
The difference between super and regular gasoline
Some people believe that when they add super gasoline to their car, it will perform significantly better than regular gasoline. They say that the word “super” indicates that this type of gasoline should be of better quality, while the term includes the characteristics of this type of fuel in terms of how it is fueled in internal combustion engines, the process of refining gasoline from crude oil and also higher prices. It is comparable to regular gasoline. The ability of the fuel to condense before spontaneous combustion is called the octane number. Simply put, the higher the octane of fuel, the more resistant it is to destructive combustion. A good fuel should be ignited only after the spark plug is ignited and its combustion flame travels slowly throughout the combustion chamber to deliver useful energy to the piston crown. It is Super 95. Higher octane means an explosion at a higher pressure, meaning super gasoline explodes later than regular gasoline.
Depending on the type of engine, each car needs different octane gasoline, which is mentioned in the car manual. Knowing the right octane number and using it during refueling is important to optimize the use of the engine and increase its useful life. It may be necessary to pay more attention to this point in the case of high-octane cars because if a car that needs regular gasoline is hit with super gasoline, it will only reduce the power of the car. If a car needs super gasoline, regular gasoline Each time before the piston reaches the highest point in the cylinder, the gasoline ignites and lowers the piston, which has not yet completed its upward movement. As a result, pressure on the piston, connecting rod, crankshaft, and valve assemblies is usually accompanied by a loud noise, and failure to pay attention to this, in the long run, will damage the engine and reduce its useful life.
The higher the altitude, the higher the fuel. It burns later as if the octane number of gasoline was higher. If you have traveled to low-lying areas such as the north of the country with your car, you must have encountered a sharp increase in engine noise, which is also due to the effect of altitude on fuel octane. To solve this problem, by adjusting the car brake, adjusting the engine with the device, and filling it, the fuel self-ignition in these cars can be raised and the noise can be eliminated. If you have traveled by your car to low-altitude areas such as the north of the country, you must have encountered a sharp increase in engine noise, which is also due to the effect of altitude on octane fuel.

Super and ordinary gasoline detection methods
How to distinguish super gasoline from regular gasoline is the first characteristic of gasoline color super gasoline is usually white and green and ordinary gasoline is reddish-pink. Another feature of super gasoline is its high jump and paleness compared to ordinary gasoline; to make sure that there is water in the super gasoline or not, pouring a few drops of super gasoline on a sheet of paper should not leave a special effect on it; If the sheet of paper has lost its smooth state, it means that the product has been soaked in water. The different smells of super and regular gasoline are other ways to detect them. The difference between the exhaust gases during refueling is also an important point in identifying products.
When refueling and placing the nozzle in the car tank, the product is not visible, the exhaust gas can be a good way to determine the type of gasoline. For this purpose, if the gas coming out of the tank was dry, it was super gasoline, if it was greasy, it was ordinary gasoline, and if it was very smelly, it was diesel. To distinguish gasoline from diesel, if the gasoline gas remains on the hand, the stain does not remain at first, but after a while, if it is not cleaned, it turns into white stains, which is a sign of gasoline.
