How to Solve the Problem of High Fuel Consumption?

[Duane]

High fuel consumption can be addressed by inspecting and repairing car components. Here are specific methods to solve high fuel consumption: 1. Clean engine carbon deposits: Excessive carbon deposits in the engine are 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 advisable to drive at high speed for a while, which helps increase exhaust volume and allows stronger airflow to remove larger carbon deposit particles. 2. Check the oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio in the engine. Once damaged, it can 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 gases 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 regularly. If not replaced for a long time, they can become dirty and affect performance, sending incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits.
