Here are the solutions for high fuel consumption in cars: 1. Clean engine carbon deposits: Excessive carbon buildup in the engine is a major cause, primarily due to the use of unsuitable fuel. It is recommended to add a certain amount of cleaning agent when refueling. After cleaning, it is best to drive at high speed for a while, as this helps increase exhaust flow and allows stronger airflow to remove larger carbon particles. 2. Check the oxygen sensor: As an internal control unit in the car, the oxygen sensor monitors the fuel-air ratio in the engine. Once it is damaged, it will cause an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. If the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust during driving, and the sensor should be replaced. 3. Regularly replace the three filters: During vehicle use, the oil filter, air filter, and fuel filter must be replaced periodically. If they are not replaced for a long time, they will become dirty and affect performance, sending incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits.

With over a decade of driving experience, I've found that poor driving habits are the most common cause of high fuel consumption. Rapid acceleration and sudden braking waste fuel unnecessarily, while maintaining a steady speed can save a lot. Low tire pressure also increases resistance, so I recommend checking and maintaining it at the recommended level regularly. A dirty air filter reduces intake efficiency, making the engine work harder and consume more fuel—cleaning or replacing it monthly is a good habit. Old engine oil reduces lubrication and increases engine strain, so timely maintenance is crucial. Additionally, excessive load increases fuel consumption, and clearing unnecessary items from the trunk can work wonders. Overall, these small adjustments can easily reduce fuel consumption, extend vehicle lifespan, and make driving more economical and hassle-free.

As an environmentally conscious individual, I pay close attention to fuel consumption as it directly relates to carbon emissions and cost savings. When fuel consumption is high, I first check if my driving habits are the issue, such as driving at high speeds with windows open or excessive air conditioning use, which increases wind resistance and fuel consumption. Maintaining a steady speed of 60-80 km/h is the most fuel-efficient. Vehicle condition is also crucial; clogged air filters or worn-out spark plugs reduce combustion efficiency, making regular inspection and replacement necessary. Proper tire pressure reduces rolling friction, so I monitor it monthly with a tire pressure gauge. Engine carbon buildup also causes a spike in fuel consumption, and using fuel system cleaners can help. By following these steps, I not only protect the environment but also save on monthly fuel costs—a win-win situation worth daily attention.

When I first started driving, my fuel consumption was extremely high. Later, I learned to check the basics. Checking tire pressure is simple—use a tire pressure gauge to see if it's below the standard value, and add some air if it's insufficient. Open the air filter and take a look; if it's dirty, replace it with a new one to improve air intake and fuel efficiency. Measure the engine oil level, and add some or change the oil if it's too low. Avoid rapid acceleration while driving, and minimize air conditioner usage in stop-and-go city traffic to reduce waste. If there's no improvement after doing these, promptly visit a professional shop for inspection—there might be a bigger issue.
