How far a 2015 Jeep Wrangler 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 18 MPG, a full 18.6-gallon tank covers about 335 miles.
| Gauge | Gallons | Highway miles | City miles |
|---|---|---|---|
| Full | 18.6 | 391 | 316 |
| 3/4 | 14.0 | 293 | 237 |
| 1/2 | 9.3 | 195 | 158 |
| 1/4 | 4.7 | 98 | 79 |
| 1/8 | 2.3 | 49 | 40 |
Over 15,000 miles a year (the EPA's yearly estimate) this configuration uses about 833 gallons, roughly 45 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.
