Does the 1984 Grumman Olson Kubvan need premium gas?

Fuel grade varies by trim — see the breakdown below.

Trim (engine / transmission)FuelMPGFuel/yr
1.6L 4-cyl, 5-spd manual, 2WDDIESEL31$2,500
1.6L 4-cyl, Automatic 3-spd, 2WDDIESEL27$2,900
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.
