I agree. It sounds more like "puff" than a knock. Could be exhaust or emission controls system. It will take time and patience to find.

Despite the fact that you put oil that no fanatic would endorse in your engine, I doubt that oil would cause something to happen this soon after an oil change. If it is a knock, it's been a long time developing.
