It is possible that old oil simply blocks up the clearances with sludge which is why the noise returns after fresh oil is put in. I doubt anyone will try this put I bet putting used 20-50 oil would stop the tick (and likely also kill the motor for other reasons).
I've had 300,000km engines that became noisy after flushing the oil.
