Does the 2020 Toyota Highlander need premium gas?
Every trim takes regular — no premium needed.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 3.5L 6-cyl, S8 automatic, FWD | REGULAR | 24 | $2,600 |
| 3.5L 6-cyl, S8 automatic, FWD | REGULAR | 23 | $2,700 |
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.
