Does the 2011 GMC Savana 1500 AWD (Passenger) need premium gas?
Fuel grade varies by trim — see the breakdown below.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 5.3L 8-cyl, Automatic 4-spd, AWD | FLEX-FUEL | 14 | $4,450 |
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.
