When the fuel tank is full, it shows a range of 302 kilometers. What could be the reason for this?

I actually forgot to turn off the engine while refueling [I want to be alone][I want to be alone]. It's fine now.

It seems like you often park your car by the roadside to rest, which can consume a lot of fuel. Idling increases fuel consumption, and using a lot of electricity inside the car also contributes to high fuel usage. Try driving more on the highway, and the fuel economy will improve.

Frequent starts and stops, only driving less than 10 kilometers, that's how it is.

Just drive it, a full tank can go over 400 kilometers.

High fuel consumption before refueling.
