You may have very worn piston rings, letting oil through. Take it for a'compression test'/
there is no water mixed with the oil but have antifreeze coming out of the exhaust
Maybe a blown head gasket
It is buring oil this is a wrong answer whe engine burn oil to the exhaust smoke is a heavy white smoke no black
Your engine is most likely overfilled with oil. Check your oil and make sure it isn't overfilled. However a little oil coming out the exhaust isn't gonna hurt anything, your just gonna waste a heak of a lot of oil
high probability you have a damaged engine
if you have blue smoke coming into the exhaust that means your piston rings are bad and are letting oil into your combustion chamber and then causing the oil to be burned with your air fuel mixture and that's why your exhaust is blue from having that burnt oil dumped out of the exhaust valve and out the exhaust
You have too much oil in your gas, that's why oil and gas is coming out your exhaust.
leaking past the rings
engine is burning oil could be valve seals or piston rings
cause so times if you crash in a rock or a tree . then the oil comes out of the pipe
Is the smoke coming out the exhaust pipe or from under the car? If its coming from under the car there could be something like oil getting on it. If its coming out the exhaust pipe you have engine problems and you should first check the oil level on the dip stick before your next oil change to see how bad its using oil.
You are burning oil. (most likely due to worn rings)
