Toyota Corolla 2004 Engine knocking Isuue

I have a 2004 Corolla, and after driving for about half an hour, it starts knocking, especially on the hilly roads of Quetta. I use 10w-30 Havoline oil, recently replaced the fuel pump with a used one from a Honda, and sometimes use Iranian fuel. Can anyone help with the knocking issue?

It seems like the gasoline youre using might be of lower quality. Try mixing in some high octane fuel o r using an octane booster, and that should likely solve your problem. Ive had a similar issue when I got fuel from HUB Chowki. Even some branded petrol pumps sometimes sell Iranian petrol to make more profit.
