Avoiding carbon buildup in cars can be achieved through the following methods: 1. Use high-quality fuel: Impurities such as paraffin and gum in fuel are the main components of carbon buildup. Therefore, cleaner fuel has a weaker tendency to form carbon deposits. Always choose reputable gas stations when refueling to ensure relatively better fuel quality. It's important to note that high quality does not mean high octane rating; the octane number only represents the gasoline's resistance to knocking, not its quality or cleanliness. 2. Avoid prolonged idling: Extended idling increases the time it takes for the engine to reach normal operating temperature, slowing the evaporation of gasoline sprayed onto the back of the intake valves, which leads to carbon buildup. Additionally, frequent idling reduces the airflow into the engine, weakening the scouring effect on carbon deposits and promoting their accumulation. 3. Drive at high speeds more often: Carbon buildup mainly occurs when the engine runs at low RPMs, resulting from incomplete fuel combustion. This is especially common in urban traffic congestion. At high speeds, the engine operates at higher RPMs, and the movement of the pistons accelerates, which can help shake off internal carbon deposits and expel carbon residue from the exhaust. 4. Change the engine oil promptly: Engine oil is crucial for the car's engine, and timely oil changes offer significant benefits, such as improving engine lubrication and inhibiting carbon buildup inside the engine. Therefore, always change the oil on time and ensure its quality.

Carbon buildup is quite annoying, and the key to avoiding it lies in driving habits. I drive at a steady pace, avoiding sudden braking or aggressive acceleration, as these can lead to incomplete fuel combustion and carbon deposits. Frequent highway driving is highly effective—running at least one highway trip per week at speeds of 70-80 km/h helps blow away carbon dust in the engine. Also, avoid prolonged idling, such as turning off the engine during heavy traffic to reduce carbon buildup. Regularly replacing the air filter and spark plugs keeps the engine running smoothly. Choose quality gasoline from reputable stations, as poor-quality fuel increases the risk of carbon buildup. Remember, smooth driving not only saves fuel but also protects your car.

Maintaining your car is a good way to prevent carbon buildup. It's recommended to regularly check the air filter, as clogging can affect air supply and lead to incomplete combustion. Replace old spark plugs promptly, otherwise delayed ignition can worsen carbon deposits. I make it a habit to clean the throttle body and fuel injectors every six months to remove existing carbon residue. Using anti-carbon gasoline additives is also effective, and choosing products from reputable brands is more reliable. Avoid idling for too long after starting the car—two minutes is sufficient, as extreme cold or heat can easily cause carbon buildup. When driving on highways, accelerate appropriately to allow the engine to operate fully. Simple maintenance can greatly reduce trouble.

Paying attention to daily driving details can prevent carbon buildup. Drive smoothly and avoid frequent acceleration and deceleration; maintain the engine at medium RPM, such as keeping it around 2000 RPM when driving in the city. Choose reputable gas stations with high-quality fuel to reduce impurities. Don't let the engine idle for more than three minutes when parked—turn it off when necessary. Take the car on the highway occasionally, as it effectively clears carbon deposits. Check the air filter every quarter to ensure clean air intake. With proper combustion, carbon buildup naturally decreases, and the car becomes more durable.
