Does the 1987 Oldsmobile Ninety-Eight Regency need premium gas?
Every trim takes regular — no premium needed.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 3.8L 6-cyl, Automatic 4-spd, FWD | REGULAR | 19 | $3,300 |
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.
