How far a 2018 Ford Fiesta goes on a tank
Gallons left and the distance they cover at each mark on the fuel gauge, at EPA city and highway mileage. At the combined rating of 30 MPG, a full 12.4-gallon tank covers about 372 miles.
| Gauge | Gallons | Highway miles | City miles |
|---|---|---|---|
| Full | 12.4 | 434 | 335 |
| 3/4 | 9.3 | 326 | 251 |

Over 15,000 miles a year (the EPA's yearly estimate) this configuration uses about 500 gallons, roughly 40 full tanks.
Fuel gauges aren't perfectly linear and the low-fuel light comes on with a few gallons still in the tank, so plan your stop before the last eighth.
