Yep - always change oil!!! Luckily this is out of a wrecked car (I would never let this happen to my car!) and hence I don't have to claim responsibility for this.
You can see that those rings (ALL THREE OF THEM) are completely stuck in and wouldn't seal for shit. Only about 4 combustion rings were still floating out of the 8 in total, and none of the 4 oil rings were floating at all.
This is how engines end up blowing a tonne of blue smoke
