Yep sounds like an AOS getting tired or too much oil in the engine.

If the O2 sensors are failing you would get the engine light coming on.

If no Dash warning lights its probably not any of the sensored things failing.

I would check codes from the computer in any case.

The AOS is not sensored so when it fails there is no indication except for a lot of smoke as extra oil starts getting sucked into the engine.

Also, make sure the oil level is down from full a couple bars just to be sure its not over full of oil.
