No knocking in my Turbo currently. Zero.
It started slight knock around 2000km mark which got worse around 3000km mark. Since then I've been using about 50:50 mix of Total regular and Total hi octane, from 2-3 specific pumps in Karachi. Now, just past the 5000km mark, after its first oil change, car is going great! I have no idea what's going to happen tomorrow, but right now its doing good.
