Does the 2015 Mercedes-Benz ML250 Bluetec 4matic need premium gas?
Fuel grade varies by trim — see the breakdown below.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 2.1L 4-cyl, Automatic 7-spd, 4WD | DIESEL | 25 | $3,150 |
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.
