How far a 2015 Cadillac Escalade 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 17 MPG, a full 26.0-gallon tank covers about 442 miles.
| Gauge | Gallons | Highway miles | City miles |
|---|---|---|---|
| Full | 26.0 | 546 | 390 |
| 3/4 | 19.5 | 410 | 293 |
| 1/2 | 13.0 | 273 | 195 |
| 1/4 | 6.5 | 137 | 98 |
| 1/8 | 3.3 | 68 | 49 |
Over 15,000 miles a year (the EPA's yearly estimate) this configuration uses about 882 gallons, roughly 34 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.
