I changed the oil in my 20 hp Vanguard B&S powered riding mower circa 1997 ish and put in Tribodyn. It could totally be the warm and fuzzy feeling and just fresh oil but I think the engine sound seems a little smoother or it seems a tad deeper tone that is a little more pleasant to the ear. It's still obnoxiously loud but maybe just a tad more pleasant. I like it.
