Does the 1990 Chrysler LeBaron Convertible need premium gas?
It depends on the trim. Some versions take premium and some take regular — check your exact engine/transmission below.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 2.5L 4-cyl, Automatic 3-spd, FWD | REGULAR | 21 | $2,950 |
| 3.0L 6-cyl, 5-spd manual, FWD | REGULAR | 20 | $3,100 |
| 3.0L 6-cyl, Automatic 4-spd, FWD | REGULAR | 19 | $3,300 |
| 2.2L 4-cyl, 5-spd manual, FWD | PREMIUM | 20 | $3,850 |
| 2.5L 4-cyl, Automatic 3-spd, FWD | 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.
