How far a 2005 Mercedes-Benz C-Class 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 16.4-gallon tank covers about 328 miles.
| Gauge | Gallons | Highway miles | City miles |
|---|---|---|---|
| Full | 16.4 | 377 | 279 |
| 3/4 | 12.3 | 283 | 209 |
| 1/2 | 8.2 | 189 | 139 |
| 1/4 | 4.1 | 94 | 70 |

Over 15,000 miles a year (the EPA's yearly estimate) this configuration uses about 750 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.
