It can be skipped. The fuel additives used for motor vehicles are optional. Related information is as follows: 1. Main functions of fuel additives: Clean the fuel system, remove carbon deposits from the fuel injectors, improve engine combustion efficiency, and restore engine power output. The cleaner is added through the fuel tank opening and can be purchased at gas stations or repair shops. 2. Maintenance items for motor vehicles during after-sales service: The main maintenance items include engine oil, oil filter, and air conditioning filter. Other items are determined based on the driver's needs. The gasoline cleaner for motor vehicles is an environmentally friendly material. After adding it, the fuel can burn more completely, reducing exhaust emissions.

I've been driving a Honda Civic for over five years, and every time I go for maintenance, the shop asks if I want to add fuel system cleaner. Honestly, it's not mandatory, but skipping it long-term might cause issues. Honda recommends it because gasoline contains impurities that can lead to carbon buildup in the engine. Without it, carbon deposits accumulate gradually, weakening the car's performance and possibly increasing fuel consumption. I once skipped it twice in a row and started noticing acceleration hesitation—later spent over a thousand bucks cleaning it up. Now I add it every time; it costs an extra hundred or so, but the car runs smoother, and it's much less hassle. I’d recommend not skipping this step, especially if you often drive in the city or areas with poor fuel quality. Regular use can extend engine life and reduce repair headaches.

From a cost-saving perspective, you can completely skip adding fuel system cleaner during maintenance, potentially saving dozens to hundreds of yuan each time. Honda's manual only recommends its use, and not adding it won't have significant short-term effects. However, you need to weigh the options: skipping it saves small amounts, but if carbon buildup becomes excessive, cleaning the fuel system once could cost thousands or more, and may even damage components. After calculating the costs, I recommend considering your driving habits: for new cars or those with low mileage, you can temporarily skip it; but for vehicles over 40,000 kilometers or those frequently used for short trips, adding it is more cost-effective. Honda's design intent is to help maintain fuel system cleanliness and prevent issues like clogged fuel injectors—not adding it carries higher risks. So, I usually find that skipping it doesn't save much in the long run, and adding it serves as preventive maintenance.

Adding fuel system cleaner benefits vehicle performance. Without it, impurities in the fuel can gradually clog the system, leading to incomplete combustion which affects power and fuel efficiency. I once skipped adding it during maintenance and within weeks noticed significantly sluggish acceleration and increased engine noise. After using the cleaner, the car responded more sharply and idled more smoothly. Honda's recommendation to use it isn't a joke – it effectively reduces carbon buildup issues. Neglecting it allows problems to accumulate and worsen the driving experience. Regular use is recommended to maintain optimal vehicle condition.
