Can the fuel additives sold at gas stations really remove carbon deposits from cars?

I believe everyone has heard of the propaganda that gasoline additives can remove carbon deposits. Some people say it's effective, others say it's not obvious, and more people may just have heard of it all the time and never tried it themselves. In particular, car owners who go to gas stations or maintenance will definitely have the experience of being promoted by staff, and then sell fuel additives like a master.

What is a fuel additive

Whether fuel additives have any effect or not is unclear to many car owners themselves. Some people just think that spending some money to buy a small insurance, but they don't know that doing so will ruin their cars in minutes. In fact, fuel additives are functional substances added to fuel in order to make up for some defects in fuel performance and give fuel some new excellent characteristics. Its addition is characterized by trace amounts, ranging from a few parts per million to a few percent.

Influence of fuel additives

At present, the fuel additives on the market are composed of BASF, Lubrizol, Chevron and Avton, and then the manufacturers add octane number improvers and detergents as needed. Then the role of fuel additives is very clear, improving the octane number of fuel and cleaning up the carbon deposits and other dirt in the engine. If it is genuine fuel treasure, continuous use for a period of time will indeed have a certain effect, clean the engine, improve the combustion efficiency, and thus achieve the effect of fuel saving.

Use of fuel additives

The use of fuel additives is actually very simple. Pour directly into the fuel tank and mix with gasoline. When the engine is burning, some components of fuel treasure will stick to the dirt and then dissolve by themselves, thus achieving the cleaning effect.

Precautions for fuel additives

Fuel additives are divided into four generations. The first generation, mainly for carburetor deposits; The second generation is mainly used for fuel injectors; The third generation mainly plays the role of nozzle, inlet valve gluing and carbon deposition; Besides cleaning fuel injectors and intake valves, the greatest progress of the fourth generation is to suppress and decompose carbon deposits in combustion chambers. These four generations of products, the new generation is developing in maintaining the functions of the old generation. It is said that the products on the market at present should be the fourth generation of fuel additives, but in fact, there are four generations of fuel additives under one roof, and everything is available.

If inferior fuel treasure is used, it will not only fail to achieve the cleaning effect, but also leave some dirt inside the engine, which is irreversible to the engine itself. What's more, the fuel additive itself will release toxic gases after burning, which is very serious to the environment. Fuel additives have been banned in most parts of the United States.

In the automobile environment with low oil quality in China, fuel additives can only be used as specific drugs forever. No matter how high-quality additives are, the effect is not as good as engine cleaning, but they can't be useless. If the specified high-grade gasoline cannot be added under special circumstances, low-grade gasoline and fuel additives can be used for emergency use.

Of course, if you insist on using fuel additives, you can always use them, provided that you choose high-quality products, as long as you don't block the three-way catalytic converter. However, I would like to remind you that the problem of carbon deposition in direct injection engines cannot be cured. If you want to maintain the engine well, you must develop good driving habits and clean the engine regularly.

abstract

Many people resisted these things at first, because many repair shops didn't like the owners. Later, they really learned that this product also has its merits. Fuel additives help to prevent carbon deposition, clean carbon deposition in vehicles and improve fuel performance, but we still have to remind everyone that when purchasing fuel additives, we need to choose them according to the situation of vehicles and our own needs, and we should not blindly buy and use them. Compared with manual cleaning of engine air intake, it is cheaper, and can better meet the fuel economy, emission and power, thus achieving the role of environmental protection and energy saving.
