in FNEI it shows the advanced spatial miner being able to produce oil, but I can't make it in my game and it doesn't seem to be blocked by technology. Just curious if it is intended or not as it would be rather useful to me in this run(island locked)

Hi! Didn't mean to take so long to reply, there was something in the code in past factorio versions, somewhere along the line I disabled the extension which allows oil to come out of it ( technology recipes are probably spread out and disabled )

I will put the oil in the "3rd ( Electric Miner ) " spacial miner. I don't mind the thought, it was just forgotten. I shall add it in (1.0.15)

By the way, what is FNEI? I don't think I've used that yet.
