It reads and tells you instantaneous and avg mpg plus exact gph readings.
Then experiment by going different speeds on the same road.
It's 16 bucks to find our what's real vs seat of the pants justifications.

I have one hooked permanently to my OBD port and it really makes you aware of how much your gas mileage goes down with a heavy foot and increased speed as well as the effect of wind and hills. It will also give you a ton of other info, if you want it, as well as the ability to read and zero out engine fault codes and the engine problem light. Invaluable to figure out whether the engine light is a real problem or a minor issue and reset it.
