When oil comes out of the tailpipe it's time to see your machanic. the Piston Rings are worn, and need to be replaced.
if it didnt do it before oil change maybe over full
Engine oil is entering the combustion chamber(s) .
oil getting by the rings causes white smoke and oil dripping out of the tailpipe.
Burning oil
You are burning oil.
------------------------------------------------------------ or the Piston Rings are bad... if it uses allot of oil.
No. A bad head gasket would cause water to come out the tailpipe. You will see white smoke. Leaky rings would cause oil to come out the tailpipe. You will see blue smoke.
water
you put too much oil in, it is burning the oil.
Steam from the tailpipe, and water in the oil means you have a faulty head gasket. Not a good thing. The steam is the antifreeze/water coolant leaking into the heads (bad gasket) getting heated by the engine and coming out as steam. The water in the oil is the same deal, but it;s collecting in the oil so it isn't coming out of the tailpipe. You need a new head gasket. I promise.
Rear main valve seal
my guess would be bad piston rings
