Does the 2009 Hyundai Genesis 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 |
|---|---|---|---|
| 3.8L 6-cyl, Automatic 6-spd, RWD | REGULAR | 21 | $2,950 |
| 4.6L 8-cyl, Automatic 6-spd, RWD | PREMIUM | 19 | $4,050 |
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.
