Does the 1990 Audi 100 need premium gas?
Every trim takes regular — no premium needed.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 2.3L 5-cyl, Automatic 3-spd, FWD | REGULAR | 18 | $3,450 |
| 2.3L 5-cyl, Automatic 4-spd, FWD | REGULAR | 18 | $3,450 |
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.
