Does the 1984 Isuzu Pickup 4WD need premium gas?
Fuel grade varies by trim — see the breakdown below.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 2.0L 4-cyl, 4-spd manual, AWD | REGULAR | 20 | $3,100 |
| 2.0L 4-cyl, 4-spd manual, AWD | REGULAR | 19 | $3,300 |
| 2.2L 4-cyl, 4-spd manual, AWD | DIESEL | 25 | $3,150 |
| 2.2L 4-cyl, 4-spd manual, AWD | DIESEL | 24 | $3,250 |
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.
