Hello, how low does the oil get and how much time does it take before you have to add oil? Obviously the engine is burning oil, ie the black smoke.

That's way too much oil to be leaking out or burned, possibilities are bad valve seals, worn out piston rings, low compression. Most likely there may be internal mechanical damage. Excess oil be burned can lead to premature catalytic converter failure. Which may have already happened.
