What are the reasons for the high fuel consumption of BYD F0?

[SanAdalynn]

Here are the reasons for the high fuel consumption of BYD F0: 1. Idling: When the car is idling, fuel continues to be consumed without an increase in mileage, which inevitably leads to higher fuel consumption. 2. Warm-up time: The fuel injection rate is high during idle warm-up. Prolonged warm-up before driving in winter can cause an increase in fuel consumption. 3. Sensor damage: Check if the oxygen sensor is damaged. The oxygen sensor primarily monitors the air-fuel ratio in the engine. Once damaged, it can cause an imbalance in the engine's air-fuel ratio, leading to a sudden increase in fuel consumption. When the oxygen sensor is damaged, black smoke may be emitted from the exhaust pipe while driving. In this case, the oxygen sensor needs to be replaced.
