if u can review your knowledge that would be even better sir. 0w/5W will only be related with cold start, and in Pakistan, that doesn't matter. Number after W is the viscosity and has ZERO relation with outside temp. 5W-20 is not readily available, so i was focused on 0w-20. This 20,30 etc is not the temperature scale sir g. So if i use 0w or 5W, it makes no difference to me, because i will not be seeing sub zero temp but if something is readily available, why not use that., No tell whats special in Pakistani air?
