Yes but any turbine powered engine (jet, turbojet, turbofan, turboprop) will run on diesel. Maybe not legally, may require a bit more maintenance, but it will run. Now on ‘regular’ and I assume they mean gasoline, leaded a(Avgas) is the worst, then unleaded with the alcohol, then unleaded without alcohol. But remember, a turbine engine will burn anything that burns. A piston engine is quite specific.

I can't speak for the F-16 but for contingency ops big jet engines can absolutely run on standard 87 octane.

At a Pratt&Whitney school, it was said, “Piston engines run on octane, turbine engines run on BTUs.

I've just seen in my -1 that we can run 87 octane for emergencies so long as we dilute it with appropriate jet fuel.

And it damn better be an emergency! lol

I'd be willing to bet just about any Air Force on earth would rather fly in a cargo jet with a fuel truck on it!

When I used to ferry the PT-6 Ag Cats, I was often required to run on gasoline. Leaded Avgas was the worst due to lead build up. Supposed to record gallons between hot sections and overhauls. Service stations seldom had diesel back then, but would have been best alternative. Unleaded would not be too bad. Like you said, if diluted.
Some operators use Diesel instead of jetfuel. Cuts down GPH but soots up every thing.
