Does the 2018 Honda Civic 4Dr need premium gas?
Every trim takes regular — no premium needed.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 1.5L 4-cyl, CVT automatic, FWD | REGULAR | 36 | $1,750 |
| 1.5L 4-cyl, 6-spd manual, FWD | REGULAR | 35 | $1,800 |
| 2.0L 4-cyl, CVT automatic, FWD | REGULAR | 34 | $1,850 |
| 2.0L 4-cyl, 6-spd manual, FWD | REGULAR | 32 | $1,950 |
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.
