Don't put too much faith in the MPG read out on the dash...they are notoriously inaccurate in many cases. On my Focus, the dash-indicated MPG is typically much greater than actual MPG (as computed via miles driven since last fill, divided by volume of gas required to fill). In some cases, dash-indicated MPG is less than actual; but in most cases, it is greater than actual. Much greater. The dash-indicated MPG reading should be used for purely amusement purposes only. If the speedometer was as inaccurate, we would all be getting tickets!
