what gas mileage should my car be getting?

You realy can't go by how far the needle moves. some cars it moves quicker the first half of gauage and second half is is like it's sleeping. only true way to measure mileage is to start with full tank drive around town for a few day and fill back up and divide into the miles driven. i had same thing just happen to me. i filled up and driving to nmra in bradenton i could almost watch the gas needle moving but when i stopped to fill up it only took 6 gallons to go 140 miles which worked out to 23 mpg.
