Blue Smoke: Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. Just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe.
If you smell it and the oil light is coming on, you might check the oil level to make sure it is okay before you burn the engine up.
It may also be leaking out side onto say the heads, exhaust manifold etc thus making you smell it more.
The car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil.
Your valve seals may be totally shot or the piston rings may be severally worn.
It seems to be burning so much that has prevented proper performance of your vehicle. I am sure if you pulled a plug or two the would be oil fouled.
You will need to get this fixed for proper operation of your vehicle.
