I'm curious as if your engine require 5W20 from the factory, and you put 5W40 or 5W50 or even 10W60 oil in it. Will the engine temp gets cooler/hotter/stays the same?
*don't ask me why I would wanna do that, but this is purely a theoretical question that got stuck in my mind for so long.
any inputs ?
