Probably more accurate than most.
Filled 3x 20l containers from local servo.
Checked calibration of pump against the volume of containers...
Filled tank... Drove a measured 500km
Topped tank from cans.
Measured remaining qty... 7.3 litres
That's 10.54l/100km and my dash said 10.4... That's close enough!
