Additive Gasoline

Gasoline, an open chain hydrocarbon.

In the industrialized world, gasoline is a vital and highly important fluid for the movement of the entire economy. This fuel is used in automobiles because of its high heat-producing power and ease of mixing with air. It is also used as a solvent for oils and fats.

Gasoline is liquid, volatile, flammable and chemically composed of hydrocarbons. In other words, gasoline is made up of molecules that are composed of hydrogen and carbon, arranged in the form of chains. Gasoline as we know it is a product derived from petroleum, which in its natural state is a pasty liquid. This pasty liquid contains a mixture of gasoline, kerosene, diesel and various other oils. In refineries such oils are separated. Each of these products has a certain boiling point, it is from this boiling point that the separations of the oils are made.

Today, the following types of gasoline are available on the market: regular gasoline, podium gasoline and additive gasoline, the latter of which generates many doubts about its use in motor vehicles. What is different about additive gasoline? Is your usage good or not? Does it increase the power of the vehicle?

Additive gasoline differs from common gasoline in that it receives from the distribution companies an additive that has detergent and dispersant characteristics. These additives work as true detergents, acting to reduce the residues left by gasoline inside the engine. These residues are unavoidable, as they come from the gasoline itself, which contains a by-product called gum. This gum is the result of the gasoline distillation process that, when subjected to high temperatures, forms a sludge that can cause the engine’s supply system to clog, causing it to spoil. The function of this gasoline is to keep the engine clean, without the accumulation of such residues, allowing for a good flow of fuel and better engine performance.

There are many advantages of additive gasoline, especially in terms of improving fuel performance. Many people believe that this gasoline increases the vehicle’s power, improving its performance on the streets and tracks, which is not true. Its function is not to improve the engine’s capacity, let alone to make it faster, but to make it clean, improving the injection system and fuel combustion, which improves its performance.
