Start by pulling the fault codes from the engine computer. A failure of a critical sensor can cause the engine to run very rich (too much fuel) which can cause a black smoke and driveability issues.

Otherwise you have a mechanical issue, if you really have oil in the exhaust and blue smoke it may be a valve seal or piston ring problem etc.

You should tow it into a repair shop for an estimate. Do not operate the vehicle in this condition.
