| Gauge | Gallons | Highway miles | City miles |
|---|---|---|---|
| Full | 13.7 | 411 | 288 |

Over 15,000 miles a year (the EPA's yearly estimate) this configuration uses about 625 gallons, roughly 46 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.
