Is it necessary to add ethanol gasoline compound additive?

[OVivian]

From the perspective of a new car, it is not necessary to add it because the first maintenance will be performed after the break-in period. From the perspective of an old car, it is necessary to add it, but it does not need to be added frequently; regular daily maintenance is sufficient. Below are the relevant introductions: 1. Introduction one: The gasoline compound additive gradually burns and expels carbon deposits in the cylinder through catalysis. The expulsion process is very mild and smooth, which can increase the engine's lifespan and extend the maintenance cycle of components. 2. Introduction two: For vehicles of a certain age, the gasoline compound additive can effectively remove carbon deposits, gum, and oil sludge from the fuel system, fuel injectors, intake valves, etc., effectively solving problems such as difficulty starting, shaking, and poor acceleration.
