Question about 1984 Nissan 300ZX
The blue smoke means that it has started consuming lube along with gas. Meaning the rings have gone. At least the oil scrapper rings would have to be changed. What happens is that when the pistons move, the oil scrapper rings clean the cylinder completely of any oil (that was here to lubricate the cylinder). Now when they move they do not scrap the oil from here, which gets burnt and produce the bluish/blackish smoke. And the proof is that you have to add oil very quickly as is happening in your case.

I would find a better mechanic, by the sounds of things the guy really don't know what he is doing, or he is just ripping you off.
Go and get a second opinion from a reputable workshop then go and take this guy to the courthouse...
In all seriousness though it is sounding like you have blown the motor and you must have a massive oil leak somewhere for it to be using that much oil.
Hope you get this sorted.
