Is it necessary to add fuel maintenance additives for a new car?

[BenjaminRose]

It is recommended to add fuel maintenance additives. In regions with better fuel quality, it is generally advised to add one bottle every 10,000 kilometers. In areas with poor fuel quality, it can be added every 5,000 kilometers. Disadvantages of not adding fuel maintenance additives: Due to the inconsistent quality of domestic fuel and poor driving conditions, vehicles tend to accumulate a large amount of carbon deposits after being used for a period of time. The direct side effects include increased emissions and carbon buildup. Excessive carbon deposits can lead to poor fuel atomization, increased fuel consumption, reduced engine power, excessive exhaust emissions, and even issues like oil burning, cylinder scoring, and engine damage. Reasons for adding fuel maintenance additives: To address the above issues, fuel additives were introduced. The primary purpose of using fuel additives is to clean or inhibit the formation of engine carbon deposits, thereby maintaining the engine in good working condition.
