Yue Ling V3 causes high fuel consumption, add 200, run 300 kilometers, help.

As far as I know, the fuel consumption of Yue Ling V3 is not high. The fuel consumption per 100 kilometers is about 7 liters. According to your description, 200 yuan of oil ran 300 kilometers, which is 100 kilometers 1 1.3 liters, which is really high. I don't know how many kilometers your car has run and under what road conditions. If it wasn't so high before, it suddenly became higher. There should be something wrong with the vehicle. I suggest you check the oxygen sensor.
