Does the 2018 Ram 1500 2WD need premium gas?
Fuel grade varies by trim — see the breakdown below.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 3.6L 6-cyl, Automatic 8-spd, RWD | FLEX-FUEL | 20 | $3,100 |
| 3.0L 6-cyl, Automatic 8-spd, RWD | DIESEL | 23 | $3,400 |
| 5.7L 8-cyl, Automatic 8-spd, RWD | MIDGRADE | 17 | $4,200 |
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.
