How accurate is Alsvin’s onboard fuel average reading compared to manual calculation?

Do you rely on the car’s digital display for fuel average, o r do you manually calculate it full tank method? How accurate is the car’s fuel meter?

The onboard fuel average display is generally close but slightly optimistic. Users doing manual full tank calculations often find that the car displays 0.5–1 km/l higher than actual mileage. For accurate results, it is recommended to use the full tank-to-full tank method once every few months.
