The car's estimated fuel usage
while you are driving??? that will literally tell us nothing unless you can also give us you speed, your exact RPM, duration at that RPM, amount of throttle being applied, what gear you are in, wind speed, wind direction (head wind, tail wind, cross wind), incline/decline of the road, the grip and drag coefficient of your car, That is a dynamically calculated
estimate of fuel economy at that exact moment if you were to prolong that exact combination of everything above. I've seen it hit over 50L/100km under hard acceleration, which is a fantastic 4.7 mpg. That's terrible fuel economy, but I know it's like that for all of 5-10 seconds tops.
The only way to accurately see fuel economy is to start at a full tank, drive until you feel like refilling the tank, log that mileage, find the difference between a full tank (13.2 gallons or 50L) and how much you filled up, then calculate the fuel economy based on what you filled versus how much you traveled in that amount of fuel.
