Does the 1994 Porsche 928 GTS need premium gas?
It depends on the trim. Some versions take premium and some take regular — check your exact engine/transmission below.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 5.4L 8-cyl, 5-spd manual, RWD | REGULAR | 13 | $4,800 |
| 5.4L 8-cyl, Automatic 4-spd, RWD | PREMIUM | 15 | $5,150 |
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.
