Is it necessary to add fuel system cleaner?

[EloiseRose]

If the car experiences shaking, unstable idling, weak acceleration, increased fuel consumption, or exhaust pollution, it is necessary to add fuel system cleaner. However, if the fuel quality is usually high, there is little engine carbon buildup, and no abnormalities are observed, then adding fuel system cleaner is unnecessary. Below is relevant information: Introduction: Currently, fuel system cleaners are also known as fuel additives. Fuel additives, commonly referred to as fuel system cleaners, are gasoline additives designed to compensate for certain deficiencies in gasoline and provide it with new and improved characteristics. They help clean carbon deposits in the system, increase octane levels, improve atomization, reduce wear, and protect the engine. For new cars: However, for new vehicles, it is not recommended to add fuel system cleaners. This allows the parts and components, especially the engine, to wear in to their optimal state naturally. Using regular fuel alone is sufficient to break in the vehicle to its best condition.
