Does the 2008 Jeep Grand Cherokee 4WD 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 |
|---|---|---|---|
| 3.7L 6-cyl, Automatic 5-spd, AWD | REGULAR | 17 | $3,650 |
| 5.7L 8-cyl, Automatic 5-spd, AWD | REGULAR | 15 | $4,150 |
| 3.0L 6-cyl, Automatic 5-spd, AWD | DIESEL | 19 | $4,100 |
| 4.7L 8-cyl, Automatic 5-spd, AWD | FLEX-FUEL | 15 | $4,150 |
| 6.1L 8-cyl, Automatic 5-spd, AWD | PREMIUM | 12 | $6,400 |
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.
