Well in that case the oil would not have an effect. Too thin might and heavier may quiet it.
But is sure sounds like "Piston Slap". The piston is pivoting in the cylinder and slapping the side walls going up and down. It usually stops as the engine heats up since they expand with heat. The oil also thickens up from 5w to 20 as well as it come to temperature. The only remedy is slightly large pistons. For that the engine needs to be torn down.
Given the miles on I would just take it to a reputable dealer and have them listen to it. But good luck on it.
