How far a 2004 Subaru Impreza 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 20 MPG, a full 15.9-gallon tank covers about 318 miles.
| Gauge | Gallons | Highway miles | City miles |
|---|---|---|---|
| Full | 15.9 | 398 | 286 |
| 3/4 | 11.9 | 298 | 215 |
| 1/2 | 8.0 | 199 | 143 |
| 1/4 | 4.0 | 99 | 72 |
| 1/8 | 2.0 | 50 | 36 |
Over 15,000 miles a year (the EPA's yearly estimate) this configuration uses about 750 gallons, roughly 47 full tanks.
In real driving: owners who log fill-ups at fueleconomy.gov average 23.3 MPG in the Impreza (25 drivers), about 370 miles on a full 15.9-gallon tank.
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.
