Check what others are doing here : Fiat 500 MPG - Actual MPG from 644 Fiat 500 owners

From my simple spindoctored mathematics, by the time the car your car is 47-years old it should be able to get up to 39.6mpg.

1970 Fiat 500 MPG - Actual MPG from 1 1970 Fiat 500 owners

Well, that's what the evidence suggests .. just wait till the car is a bit older.
2003 Renault Scenic - 30% more power with no loss in fuel economy.
1991 Toyota GT4 - more economical before ST215W engine-swap.
previous: Water-Injected Mitsubishi ~33% improved.
future - probably a Prius
