Are there any restrictions for fuels used in experimental exhibition

and gasoline for a lower priced fuel.

I'm sure there are no "automatic" restrictions. The only restriction the
FAA might impose is a limitation on carrying passengers, and unless it's
the trainer version of the -15, that point would be moot.

Besides, even for a certified airplane, all the FAA can do is require you
use the fuel the aircraft/engine manufacturer specifies. The Russians were
pretty ingenious when it came to low-tech solutions; they may even have
approved a diesel/gas mixture for the MiG-15 as an expedient combat
logistics solution.

In Don Engen's book, "Wings and Warriors," he tells us that the Navy
fueled the early carrier jets with 115/145, because they had to share
fuel with Corsairs and Skyraiders. BTW, gasoline does not yield as much
thrust as kerosene.

The main thing you have to watch out for in jets is water contamination
in Diesel fuel, as the water will freeze at altitude and ruin your day.
