What are the benefits and drawbacks of carbon deposit cleaning?

[OLydia]

Regular carbon deposit cleaning offers many advantages, with the main drawback being increased fuel consumption. The key benefits are reflected in the following aspects: 1. Helps restore and enhance vehicle power: Improves the stability of the fuel system operation, thereby restoring or enhancing engine power and design parameters. 2. Cleans the fuel system: Removing carbon deposits helps reduce the side effects of high sulfur and aromatic hydrocarbons in fuel, improving fuel quality to meet Euro 4 standards. 3. Saves fuel: Many car owners may notice that fuel consumption tends to increase after carbon deposits accumulate. This is primarily due to incomplete fuel combustion. Regular carbon deposit cleaning helps improve fuel molecular chains, thereby increasing gasoline octane ratings and combustion efficiency, leading to reduced fuel consumption. 4. Improves emissions: Regular carbon deposit cleaning enhances fuel quality, reduces the content of harmful components in emissions, and lowers PM2.5 emissions. 5. Reduces maintenance and extends lifespan: Regular carbon deposit cleaning can decrease the likelihood of engine knocking, eliminate the negative effects of cold starts on the engine, remove moisture from the fuel system to prevent rust, and avoid corrosion in the fuel system.

As a car enthusiast, I often discuss maintenance issues. Cleaning carbon deposits offers many benefits: it can make the engine run more smoothly, improve fuel efficiency, and typically save 5-10% on fuel costs; acceleration response becomes quicker, eliminating sluggishness when climbing hills; it also reduces exhaust emissions, making it more environmentally friendly. Additionally, long-term neglect of cleaning can lead to carbon buildup clogging the engine, increasing the risk of overheating, while regular cleaning can extend the engine's lifespan. However, there are also significant drawbacks: improper cleaning methods, such as using low-quality chemicals, can corrode the cylinder interior or damage sensors; the cost is substantial, averaging several hundred yuan per session, which is wasted if ineffective; for older cars, cleaning may trigger new issues, such as oil leaks or increased engine vibration. It's advisable to decide based on the car's condition, checking every 20,000-30,000 kilometers, and avoid being oversold on unnecessary services.

As an average driver, I've noticed that cleaning carbon deposits makes the car run smoother. The benefits are obvious: reduced fuel consumption—previously a full tank would last 500 km, now it can go up to 550 km, saving a lot of expenses; quicker power response, making overtaking effortless; and reducing carbon buildup also prevents stalling or difficulty starting. However, there are downsides: if you go to an unreliable shop just to save money, the cleaning might not improve the situation or even make it worse; additionally, the chemicals used in the process can be harmful to health, emitting pungent odors during operation; frequent cleaning is not only a waste of money but may also be unnecessary for new cars. I only clean when there are clear symptoms, such as unstable idling.

As a car owner, cleaning carbon deposits can improve engine performance, reduce vibrations and noise, making driving more comfortable; it can also optimize combustion efficiency, saving fuel and reducing emissions. The downside is that cleaning may damage engine components or incur additional costs, so it's recommended to choose professional services to avoid risks.
