Hydrogen-oxygen carbon cleaning is necessary. Here is some extended information: 1. Principle: A machine is used to electrolyze water into hydrogen and oxygen, and then the hydrogen is directed into the engine's combustion chamber. Utilizing hydrogen's high permeability and high calorific value, the carbon deposits in the combustion chamber are effectively cleaned. This method is relatively thorough and quite effective. 2. Drawbacks: It may cause damage to the vehicle's catalytic converter, especially for older models. Some components of the car may already be aged, and if these critical parts are prematurely worn out due to carbon cleaning, it would not be cost-effective to replace them.

I've tried the hydrogen-oxygen decarbonization method a few times myself and don't consider it a must-do routine maintenance. This process involves equipment that generates a mixture of hydrogen and oxygen gas, which is then drawn into the engine for combustion in an attempt to burn off carbon deposits. It can clean some mild carbon buildup, such as deposits on the throttle body or intake tract surfaces, but its effectiveness is limited—especially against deep-seated, hardened carbon deposits, where it's practically useless. Whether it's necessary depends on your vehicle's condition: if your car idles smoothly and accelerates without hesitation, it's completely unnecessary; but for older vehicles or those experiencing idle vibration and increased fuel consumption due to long-term urban short-distance driving, it might be worth a try. However, the cost isn't low—several hundred yuan each time—making it less economical than simply using quality fuel additives or taking the car for a high-speed run. Prevention is key: use good-quality fuel and avoid prolonged low-speed driving.

As a car owner, I used hydrogen-oxygen carbon cleaning when I was younger, spending nearly 400 yuan. After the procedure, the engine felt smoother, but the effect only lasted a few weeks. Eventually, I resolved the carbon buildup issue through regular maintenance. The necessity varies by individual: it's completely unnecessary for new or well-maintained cars, but if severe carbon buildup causes performance issues, it can provide short-term improvement. The key is prevention through driving habits, like taking the car on a highway run every weekend to burn off deposits at high RPMs—it's cost-effective and works. Compared to this, hydrogen-oxygen cleaning isn't as thorough as manual disassembly cleaning. I recommend treating it as a backup solution rather than relying on it too much.

Hydrogen-oxygen carbon cleaning is not a must. I've driven several cars and never had this done. Instead, I prevent carbon buildup with good habits: using high-quality gasoline, avoiding prolonged idling, and occasionally driving on highways. Only consider trying it if your car shows issues like coughing during acceleration or unstable idling. But the effect is usually mediocre, and spending a few hundred bucks isn't as cost-effective as buying a reliable fuel additive. Don't waste money on new cars.
