I bought a jug of the new valvoline, i was going to put it in a 2022 mitsubishi mirage that has 22k miles on it, currently I have penzoil ultra platium in there. When i do the next oil change at 3k miles, I was going to cut open the filter, and inspect it, take some pics. then use the valvoline and compare the filters. I think if I were to use the valvoline in my 9-7x with 155k on it, I would change the oil filter after about 1500 miles, just out of caution. but I can't say I'm 100% sold on the idea that this oil will completely clean out an engine. They even say as much right on the bottle, "Removes up to 100% of deposits With Continuous Use" I translate that to, it takes as many years to clean the engine as it did to get it dirty
The other thing is, I don't think Valvoline restore and protect has the dexos cert. I'm not entirely sure that matters, but it does mean something. But that's for you to decide. Maybe you shouldn't let it in there past 5k miles
