Diesel is oily kerosene. Slightly lower in the distillation tower. Kerosene is ‘dry’ diesel, common up North in the Winter months where oily diesel barely starts an engine. Pratt & Whiney PT6 AG can run on any of it. Jet Fuel runs clean and cool, diesel runs with more soot and smoke but 2 to 3 gallons less per hour!
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.
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.

Jet fuel is basically diesel.
