Instead of running a 5 or 10-40 then adding treatments, do the opposite. Run a 5-20 and don't add thickeners (oil treatments)
The thinner the oil, the faster it will get to the top end.
The loudest my 4.0 ever rattled was after adding lucas... Thinner oil will do wonders, I learned this by having to wait a month after an oil change for it to quiet down. Then, I tried 5-20 and the thinner oil kept it quieter right out of the gate for sure.
A lot of people say to add oil treatments for loud engines not realizing that a lot of time the problem is that the oil is already to thick. By adding treatments your thickening it even worse. 3 years ago, I'd have said to add lucas. Then, I learned that it made my engine a lot louder whenever I would try it.
