Isn’t the issue less what you ask the oracle, and more how you can be sure that in order to answer the question the oracle (or whatever it self-modifies into) won’t turn you and the rest of the planet into computronium? As such, it seems that the only questions you could safely ask an oracle would be ones that you are sure are computationally tractable, or that you are sure the oracle could easily prove to be unsolvable.
