If the fuel quality is good and the engine is in good condition, there is no need to add fuel additives or engine cleaners. Here are the relevant details: 1. Comprehensive Features: The 10th-generation CIVIC (Civic) impresses not only with its exterior but also with its interior. The 7-inch central control screen adopts a semi-floating design, integrating mainstream functions such as navigation, music, and entertainment. The system operates at a mainstream level with fast response times, clear interface logic, and ease of use. Notably, the high-end models are equipped with the Honda-CONNECT intelligent navigation system, featuring real-time traffic updates, weather forecasts, and congestion/accident avoidance route guidance. 2. Excellent Experience: The multimedia system of the base models supports Apple CarPlay, making it very convenient to use. The diversified central control layout integrates the ECON intelligent green energy-saving assistance system, engine energy-saving auto start-stop system, automatic parking system, and electronic parking brake, delivering a comfortable and tech-savvy touch experience. The vehicle boasts a 2700mm wheelbase, ensuring superior and comfortable space layout.

I've driven a 10th-gen Civic for several years, and the engine has over 60,000 kilometers on it. I feel there's absolutely no need to add any cleaning agents. Honda's engine design is quite smart—regular maintenance is enough to prevent carbon buildup. Cleaning agents are mainly for older cars or those with issues, like engine shaking or sudden increases in fuel consumption. New cars run smoothly, and adding them unnecessarily might leave chemical residues in the fuel system, damaging seals. My advice is to change the oil regularly, replace the air filter, avoid sudden braking, and drive more on highways to keep the exhaust clean. From my experience, the Civic is quite sturdy—don't overcomplicate things to save money and stay worry-free. If you have any doubts, just get it checked at a 4S shop.

After driving for over a decade, I believe from a fuel-saving and environmental perspective, the 10th-gen Civic doesn't need engine cleaning additives. These products contain many chemical components—while they may treat carbon buildup, they increase emissions and pollute the air. The Civic already has low fuel consumption, and with proper maintenance, carbon buildup is minimal. Using additives is a waste of money and may cause side effects. For genuine prevention, cultivate good driving habits: avoid short trips with cold starts, and use cruise control more often to reduce carbon deposits. Regular oil and filter changes better protect engine longevity than additives—more practical, eco-friendly, and cost-effective. Civic owners I know follow the maintenance manual, easily reaching 100,000 km without issues.

Having some experience with auto repair, I don't think adding cleaning agents to the 10th-gen Civic is necessary. The engine internals are well-optimized, and regular oil changes are sufficient to prevent dirt buildup. The quality of cleaning agents varies greatly, and poor-quality ones may even cause blockages or damage components. Honda recommends following the manual for maintenance, and only consider cleaning if there are signs of carbon buildup, such as unstable idling. Regularly check the oil level and have professional inspections at scheduled intervals—it's cost-effective, reliable, and effective. The Civic's engine is durable; new owners shouldn't listen to rumors and should stick to proper maintenance for the best results.
