Gas turbines (which includes jet engines) can potentially use a lot of different fuel sources. For example, the M1 Abrams tank can run off a variety of different fuels. If it’s liquid and burns, it’ll probably work. Turbofan engines may need to be redesigned to accommodate a different fuel source, but there isn’t any reason you can’t use automotive gasoline to power a jet. It’s just not a good idea because it vaporizes more readily on the ground, has less power per volume, and freezes in the temperatures jet operate in. Piston engines aren’t as flexible. They don’t inject fuel in a constant stream, they compress and explode it.
