How far a 2015 Chevrolet Express 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 13 MPG, a full 31.0-gallon tank covers about 403 miles.
| Gauge | Gallons | Highway miles | City miles |
|---|---|---|---|
| Full | 31.0 | 527 | 341 |
| 3/4 | 23.3 | 395 | 256 |
| 1/2 | 15.5 | 264 | 171 |
| 1/4 | 7.8 | 132 | 85 |
| 1/8 | 3.9 | 66 | 43 |
Over 15,000 miles a year (the EPA's yearly estimate) this configuration uses about 1,154 gallons, roughly 37 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.
