Does the 2003 Ford Thunderbird need premium gas?
Every gas trim of this model takes premium.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 3.9L 8-cyl, Automatic 5-spd, RWD | PREMIUM | 18 | $4,300 |
| 3.9L 8-cyl, Automatic 5-spd, RWD | PREMIUM | 18 | $4,300 |
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.
