Is it necessary to remove carbon deposits from cars?

It is necessary to remove carbon deposits from cars. Here is an introduction about carbon deposit removal: 1. Damage to the vehicle: Engine shaking, weak driving, poor acceleration, difficulty in cold starts, increased gasoline consumption, high engine oil consumption, engine failure, shortened lifespan of spark plugs, oxygen sensors, and three-way catalytic converters. 2. Methods to delay carbon deposit formation: No need for excessively long warm-up; about half a minute of idling is sufficient for low-speed driving, which fully meets the needs of city driving as long as you avoid heavy throttle and immediate high-speed driving. Prolonged warm-up only wastes fuel and increases carbon deposits without any benefits. Additionally, intermittent high-speed or high-RPM driving can help delay carbon deposit formation. On the other hand, if carbon deposits do form, thorough cleaning is still required to resolve the issue completely.
I've been driving for almost 20 years and believe carbon deposit removal is necessary. Carbon deposits are tar-like residues left in the engine, which easily accumulate from prolonged city driving at low speeds or using low-quality fuel. If your car experiences idle vibration, increased fuel consumption, or sluggish acceleration, it's likely due to carbon buildup. Untreated deposits may damage engine components. I always use quality fuel and apply fuel additives every six months for prevention - those OTC products are simple yet effective. For severe cases, professional cleaning of fuel injectors or intake systems is needed, costing a few hundred yuan but extending engine life. With proper maintenance, even a 10-year-old car can run as smoothly as new, saving both hassle and money.
