I am actually bad when it comes to this. I never "calibrated" my old SG-I beyond engine size. The engine size is critical. Double the engine size and you will see your reported MPG drop like a rock.

In my fuel log I use my odometer (after GPS correction factor) and (US) gallons measured at the pump. This puts me at the mercy of gas pump innacuracies, but you can't have everything, so I can live with that. I use the same pump when available, but not at the expense of my or another's convenience.

Because I don't have a calibration factor, my instant and average MPG may be off. However, I consider them to be valid *relative* barometers, and I am fine with that.
