Does the 2024 Lexus TX 500h AWD need premium gas?
Every gas trim of this model takes premium.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 2.4L 4-cyl, S6 automatic, AWD | PREMIUM | 27 | $2,850 |
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.
