Does the 1992 BMW 318i/318iS need premium gas?
Every gas trim of this model takes premium.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 1.8L 4-cyl, 5-spd manual, RWD | PREMIUM | 22 | $3,500 |
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.
