Does the 2019 Mazda CX-5 2WD need premium gas?
Fuel grade varies by trim — see the breakdown below.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 2.5L 4-cyl, S6 automatic, FWD | REGULAR | 28 | $2,200 |
| 2.5L 4-cyl, S6 automatic, FWD | REGULAR | 25 | $2,500 |
| 2.2L 4-cyl, S6 automatic, FWD | DIESEL | 29 | $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.
