Does the 2014 Ford Mustang 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 6-spd, RWD | REGULAR | 23 | $2,700 |
| 3.7L 6-cyl, 6-spd manual, RWD | REGULAR | 22 | $2,850 |
| 5.0L 8-cyl, Automatic 6-spd, RWD | REGULAR | 20 | $3,100 |
| 5.0L 8-cyl, 6-spd manual, RWD | REGULAR | 19 | $3,300 |
| 5.8L 8-cyl, 6-spd manual, RWD | PREMIUM | 18 | $4,300 |
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.
