How far a 1991 Ford Ranger 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 23 MPG, a full 16.3-gallon tank covers about 375 miles.
| Gauge | Gallons | Highway miles | City miles |
|---|---|---|---|
| Full | 16.3 | 424 | 342 |

Over 15,000 miles a year (the EPA's yearly estimate) this configuration uses about 652 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.
