Hey guys, none car guys here. I have the car listed in the title, around 40K km ago I had a broken piston probably due to the well known LSPI problem in these engines, i replaced the pistons and had the turbocharger rebuilt (mechanic said it was causing a problem, can't remember what).

Car's been running ok, I remember seeing specific oil recommendation to prevent this problem but now when looking up which oils are those i'm seeing some mixed results and not sure what the official recommendation is.

Can anyone help me with which oil will be the best? and what other precautions should I take to ensure longevity?
