Why is the fuel consumption of Hongqi cars so high?

[McMiguel]

There are many factors that affect fuel consumption, such as tires, engine, oxygen sensor, etc. Here are some detailed explanations of these reasons: Tires: If the tire pressure is insufficient, fuel consumption will increase. If the tire pressure is normal, then check the wear degree of the tires. When the tires are severely worn, slipping signs often occur, which will also increase fuel consumption. Engine: If there is a large amount of carbon deposits in the engine in a short period, it can also cause high fuel consumption in the car. This situation is likely due to the use of unqualified fuel. Oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio of the engine. Once it is damaged, it will cause an imbalance in the engine's fuel-air ratio, and fuel consumption will inevitably increase abnormally.
