| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 2.3L 4-cyl, 5-spd manual, FWD | REGULAR | 24 | $2,600 |
| 2.3L 4-cyl, Automatic 3-spd, FWD | REGULAR | 23 | $2,700 |
| 2.3L 4-cyl, Automatic 3-spd, FWD | REGULAR | 22 | $2,850 |
| 3.3L 6-cyl, Automatic 3-spd, FWD | REGULAR | 21 | $2,950 |
| 2.3L 4-cyl, 5-spd manual, FWD | PREMIUM | 21 | $3,650 |
| 2.3L 4-cyl, 5-spd manual, FWD | PREMIUM | 20 | $3,850 |
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.
