Does the 2018 Jeep Cherokee FWD need premium gas?
Fuel grade varies by trim — see the breakdown below.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 2.4L 4-cyl, Automatic 9-spd, FWD | REGULAR | 25 | $2,500 |
| 2.4L 4-cyl, Automatic 9-spd, FWD | FLEX-FUEL | 25 | $2,500 |
| 3.2L 6-cyl, Automatic 9-spd, FWD | MIDGRADE | 24 | $3,000 |
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.
