Hot Shot is 50% R22, 1.5% R600a, 39% R124 and 9.5% R142b.
R22 is Chlorodifluoromethane
600a is isobutane.
R124 is Monochlorotetrafluoroethane
R142b is 1-Chloro-1,1-difluoroethane
Its a strange mixture having flurocarbons as well as 39% isobutane (a hydrocarbon).
Hard to tell what interaction it might have with the oils in the system.
I would personally stick to Durocool which you know is compatible with either mineral oil or ester (synthetic) oil.

Thanks Emery,
What an alphabet soup mix.
That sure makes HC-12a look like a good idea.
No wonder the people that brought us Gasahol don't like it.
