How far a 1993 GMC Sierra 1500 goes on a tank

| Gauge | Gallons | Highway miles | City miles |
|---|---|---|---|
| Full | 34.0 | 578 | 476 |

Over 15,000 miles a year (the EPA's yearly estimate) this configuration uses about 1,000 gallons, roughly 29 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.
