I should have paid attention when I put it in my wife's car. Not sure how many miles I got on this OCI, but the MM is at 50%. I don't really drive the car so it's hard for me to notice. Not to mention, the car is kinda loud being 11 years old and the CC2s with a good amount of miles on them.
Valvoline Restore and Protect drawbacks?

I haven’t done UOA but of interest, there is a YT channel called Factotum Life where he’s using it in a Pentastar, getting good results, and UOA shows Valvoline Restore and Protect starting to drop out of viscosity around 5k.
If it’s loading up with dissolved deposits, maybe that’s when folks are noticing the noisier operation?
Also, Valvoline calling it the ‘highest performing’ is marketing. I’m a believer and it’s in 2 of my vehicles as we speak, but everyone of their oils has a formula and application. Highest performing is subjective. Their HM vs EP vs HMEP all run different ‘performance’.
I think the noisier engine operation is mostly due to drop in viscosity than dissolved deposits as most of them get caught by the filter. Plus, Valvoline Restore and Protect is designed to clean your engine slowly, so it doesn't overwhelm the oil filter. That is why at least 4 OCI are required.
Dissolved means they wouldn’t be caught in the filter. Filters would catch things in suspension. Not everyone here with good results with Valvoline Restore and Protect saw things caught in their filters.
Good point. Very true.
All those resudue in the filter is dissolved sludge. The oil cannot clean varnish and sludge before it dissolves it. How much get in the filter and how much stays in the oil is different question.
The main question is how that makes the engine lowder?
In a strict sense, no. If something is actually in solution it can't be filtered out. Just like you cannot filter out salt once you've dissolved it in water. There are methods to remove salt from water but not a mechanical filter.
What you're saying is that the product weakened the bond of the material and then the material was in suspension, and may or may not be filtered out. This is what Valvoline states which is a bit contradictory:
I believe Valvoline is saying Valvoline Restore and Protect is their highest performing oil .
I tend to take the manufacturers word and therefore I consider Valvoline Restore and Protect to be their highest performing product. It could be marketing and I see his point. I have no reason not to believe them though. Everything they've said about Valvoline Restore and Protect was true. Valvoline also can run every engine test internally so they would know what product of theirs is the best.
I’m mostly a lurker here, and an intermittent lurker at that. I’m curious, many here on BITOG seem to consider R&P to be a cleanup/short OCI only oil. AFAIK, Valvoline doesn’t say anything like that in any of their materials 
I’m researching 0w20 prospects for a not too soon oil change in a new to me, very low miles 2024 Hyundai Tucson plug-in hybrid. It will be under warranty for most of the next decade so only 0w20s will be going in it, and I’ll be following the OLM unless I come across some reason not at some point. Is R&P not a good choice for me?

So how those dissolved in the oil makes the engine of some people louder, usually around 3,000 miles after the oil change?
Also if the oil dissolves and has in suspension some deposits how that makes the oil lose viscosity and and not increase the oil viscosity? What we see in most UOA.
If we take the sample of the water and the salt - when the salt gets dissolved in the water the viscosity of the water increases, does not decreases.
The loudness is prbly the CC2s lol. I changed out wheel bearings before I realized cross climates suck. I pulled a set off with a tone of tread, they wear like iron. Also ride and sound like it.
The car was loud before the CC2s but it might be louder now. I still have plenty of tread left on them so they won't be replaced for a while. I did just have a wheel bearing done last year. I was having this sound starting at 40mph and it sounded like it was from the front passenger side. Turns out, it was the rear passenger side. I mentioned it to the shop and they didn't realize it until after they replaced the rear brakes so they had to remove everything, replace and reinstall.
If you say so.
I'm not saying, just asking questions.
How the oil dissolves deposits and at the same time loses its viscosity, and not the opposite - increases its viscosity?
How those dissolved deposits make the engine louder?
It makes more sense that the engine gets louder because the oil's viscosity drops. But how did it drop when there is dissolved deposits in the oil vs when the oil is virgin?

Look in your owners manual and see what it says for oil choices and for severe service schedule. The 2 Hyundai's I currently service '21 Tucson 2.0 and '21 Sonata 2.5 both have the MM but you decide the interval. The Tucson was very short trips, fuel dilution that oil level on dipstick would rise. 5W-20 was recommended, 5W-30 optional. I bumped up a grade to 5W-30 using Valvoline Restore and Protect, changed interval to 3k/6 months. My son just changed the MM to 4k/6 months as drives are now about 20 minutes each way.I’m mostly a lurker here, and an intermittent lurker at that.

The Sonata didn't have the MM activated and records were "not so good" of last change. That now has 5k/6 months enabled but sees at least 30 minute drives most of the time. When it first came to me it was almost 2qts low, needed a top off a bit later. Currently on 0W-20 Valvoline Restore and Protect and at 2100 miles in hasn't used any oil.
The severe service schedule according to Hyundai is what I consider normal. Up hills, down hills, dusty, extensive stop/go, salt and probably 10 others like sunny, windy, rainy, cloudy or any day that ends in Y.
They really makes no sense, or at least I’m unable to figure it out.I'm not saying, just asking questions.
