Is the automobile additive good? How many additives are there?

Fuel additive, a familiar and unfamiliar automobile product, is equivalent to automobile maintenance when used correctly, but many people still don't know how to use it, so they have to ask old drivers to bring it. Fuel additives are divided into automobile additives and diesel additives, but the components of the two additives are similar, so I won't introduce them separately here. Fuel additives are mainly divided into BASF, Lubrizol, Chevron and Afton, and manufacturers will add other materials to them according to the characteristics of products. Cars often appear abnormal because of excessive carbon deposition in the engine, such as poor fuel supply, idling jitter and often inexplicable flameout. Fuel additives can improve the existing problems of oil products, effectively inhibit the generation of carbon deposits, improve the octane number of fuel, and bring great value to car owners. This additive is used when the fuel supply of automobiles is not smooth and there is too much carbon deposit. The three additives that can clean the carbon deposit on the intake manifold, valves and fuel nozzles are clean. This additive is different from the clean one just now. This additive is to inhibit the generation of carbon deposit and ensure the normal and effective operation of valves and nozzles. As shown in the figure, these three additives are all maintenance-oriented. This fuel additive is mainly the octane number of fuel, that is, the antiknock index of fuel. The higher the octane number, the better the antiknock performance. Generally speaking, the higher the oil, the more octane number, such as 95# and 97#, so vehicles with low oil can use this fuel agent.
