Does the 2012 GMC Savana 2500 2WD (Passenger) need premium gas?
Fuel grade varies by trim — see the breakdown below.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 4.8L 8-cyl, Automatic 6-spd, RWD | FLEX-FUEL | 13 | $4,800 |
| 6.0L 8-cyl, Automatic 6-spd, RWD | FLEX-FUEL | 13 | $4,800 |
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.
