Does the 1985 Grumman Olson Kubvan need premium gas?
Fuel grade varies by trim — see the breakdown below.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 1.6L 4-cyl, 5-spd manual, FWD | DIESEL | 31 | $2,500 |
| 1.6L 4-cyl, Automatic 3-spd, FWD | DIESEL | 26 | $3,000 |
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.
