How to Solve High Fuel Consumption in Small Cars?

[Steven]

The solutions for high fuel consumption in small cars are as follows: 1. Clean engine carbon deposits: Excessive carbon deposits in the engine are a significant cause, mainly due to the use of unsuitable fuel. It is recommended to add a certain amount of cleaning agent when refueling, and after cleaning, it is best to drive at high speed for a while, which helps increase exhaust volume and allows stronger airflow to carry out 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 of the engine. Once damaged, it will cause an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. After the oxygen sensor is damaged, the vehicle will emit darker exhaust from the tailpipe during driving, at which point the oxygen 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 will become dirty and affect performance, sending incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits.
