What Are the Reasons for High Fuel Consumption While Driving?
2 Answers
Low tire pressure: When the tire pressure is too low, it's like riding a bicycle with flat tires—it's hard to pedal. The same goes for cars. This not only increases fuel consumption but also poses many safety hazards, especially when driving on highways, where low tire pressure can easily lead to blowouts. Air filter clogging: Replacing the air filter can help. If the air filter is not cleaned for a long time, dust accumulates, reducing the engine's air intake and preventing fuel from burning completely, which increases fuel consumption. In severe cases, it can even affect the engine's lifespan. Engine carbon buildup: Over time, some carbon buildup is inevitable in the engine. Frequent driving in congested areas or at low speeds can easily lead to excessive carbon deposits. Too much carbon buildup can reduce engine power and increase fuel consumption. It's advisable to check the engine's carbon buildup condition.
I noticed high fuel consumption while driving, mainly due to my aggressive driving habits. For example, accelerating sharply right after starting, braking hard at red lights, or driving too fast on highways—these actions waste a lot of fuel. Later, I switched to smooth starts and steady driving, which saved me a lot on fuel costs. Additionally, avoiding frequent lane changes or sudden throttle presses in traffic jams and maintaining a safe distance also reduces fuel consumption. When the car is coasting in neutral, the engine still burns fuel, so avoiding prolonged idling at traffic lights is also important. After adopting these good habits, driving became more relaxed, and my monthly fuel expenses dropped by over 100 yuan.
