How far a 2015 Dodge Grand Caravan 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 20.0-gallon tank covers about 400 miles.
| Gauge | Gallons | Highway miles | City miles |
|---|---|---|---|
| Full | 20.0 | 500 | 340 |
| 3/4 | 15.0 | 375 | 255 |
| 1/2 | 10.0 | 250 | 170 |
| 1/4 | 5.0 | 125 | 85 |
| 1/8 | 2.5 | 63 | 43 |
Over 15,000 miles a year (the EPA's yearly estimate) this configuration uses about 750 gallons, roughly 38 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.
