The last five cars (different brands) had the computer that gave you the

I go by a ScanGauge plugged into the ODB. When I fill up it is usually
within a tenth of a gallon on how much will take to fill the tank and
the tank mpg numbers jibe with the odometer.

cost of fuel is only one of the variables ... how much to get a mile down the
road is the bottom line. AAA says..

The metric is "miles per GALLON (of fuel)" -- not miles per DOLLAR.
