HOGE. No problem. Just requires a write-up at least in the Huey. Many times in the old days when we had long x/c flights in the states we used to take on a bit of avgas.... Cant do it everytime, but it works. Write up I think required a hot end check after so long....
Now in a recip things will get quiet real quick if you dump in Jet A. Most recent I remember was a twin in San juan
PR. It got off the end of the runway before the engines said." nope thats Jet A ,I quit"
