Does the 1991 Geo Metro LSI Convertible need premium gas?
Every trim takes regular — no premium needed.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 1.0L 3-cyl, 5-spd manual, FWD | REGULAR | 37 | $1,700 |
| 1.0L 3-cyl, Automatic 3-spd, FWD | REGULAR | 30 | $2,100 |
The EPA records the fuel each version was tested on. Whether premium is strictly required or just recommended is an owner's-manual detail the EPA dataset doesn't include — so we don't guess it.
