I've not heard that before. Is that similar to viscosity shearing over time?

Looking good. I wasn't sure how VRP would handle varnish but it looks like it cleans that up too. One of the Valvoline Tech guys told me a while back it will clean all metal surfaces it comes in contact with.
Glad you stuck with it for the 3 to 4 OCI's. Using it as intended.
Unless they changed the formulation Adam, but it does contain about 11% TMP ester. It's a decent cleaner...
Very good info. What else is in it? I wouldn’t use it personally as I have no use for it
I believe @MolaKule's graduate students did a voa on this a while back. Maybe he can reveal what else is in it.
I would't use it either but I can see folks that can benefit from it.
I believe it is why some oils are more sensitive to lowering their cSt over time. A 5W30 has more base oil (less percentage viscosity modifier) in the recipe than a 0W40. In UOA's 0w40 often fall into 30 grade over time. I haven't noticed anyone doing centipoise measurements though.

Here is the analysis from a 2018 post:
"What TRAV said.
Here is the latest summary Analysis I have:
Rislone Engine Treatment from quart bottle (32 oz.) version.
Physical Tests:
Viscosity (cSt 100C) 8.0
Additives (ppm):
Magnesium (Mg) 3
Calcium (Ca) 1935
Phosphorus (P) 422
Zinc (Zn) 503
Boron (B) 8
TMP Ester 11% by weight.
When I had my 2003 PathFinder I had a sticky Variable Valve Control valve that caused a power reduction situation and within 10 miles it cleared it up.
Much depends on what is causing your tick.
If it is a dirty hydraulic valve lifter this may help, but if the problem is purely mechanical and it needs a lash adjustment due to worn components, no liquid cleaner will cure it."

how big is that rislone bottle? I wouldn't expect a total concentration of 1% TMP (10 to 1 dilution with engine oil) to have such success in 10 miles.

I am reporting exactly what happened in this situation with our old 2003 PathFinder back when this happened. On my trip down to KY from Iowa, I started having a power reduction on uphill climbs in Mo. When I got to my dad's I told him of the situation and he sent me to a mechanic in town who had been a Nissan-trained mechanic at a Nissan dealer, and it was this mechanic who suggested the Rislone. I had my doubts that any cleaner would clear the problem, but I took his suggestion anyway.
BTW, I only added 16 oz. or half a quart to see if there might be even a small improvement as I drove home from the auto supply store back to my dad's house. My thinking was if I saw some improvement, then on my way back home, I would add the rest to gain more improvement if the problem persisted, but I did not have to add any additional cleaner. Why add the rest when 16 oz. removed the carbon from the VVT valve?
Since the introduction of HPL's EC, I now use HPL's cleaner exclusively because of its additive pack and ester complement.
I called Valvoline to ask them if they had any plans on making it dexos approved. He said it would absolutely meet the requirements but they don't see the need to spend the money on the certification at the moment. He also said they're getting a lot of inquiries on whether there will be a European grade and he said most likely there will be. He did mention that competitors are trying to come out with their own version. Not sure what he meant by that or how he would know that. He might have just been making a general statement that they likely will try being the product claims to be a new technology that no other oil can currently match at the moment.
Thanks for sharing. A Euro version might be the ticket for me trying it in my E-150, if they don't roll out a 0W40 or 5W40. Regarding the competition, probably an educated guess, or trade chatter among friends in the industry. The product is gaining momentum, it would make sense for the competition to take a shot at it as well.
Not to simplify it too much, but if consistent reports/evidence that it does clean this well continue to build, could one say this is very much like an HPL oil (as far as intensive cleaning abilities) but not for extended drain intervals?
I would say so. Remember Valvoline did the testing already and designed it to clean over 4 OCI's. There is something unique in VRP that enables it to clean the really hard piston deposits. Sludge and varnish are different. Beyond that, it won't match Amsoil SS/HPL in other areas such as long drains etc.

Hello all.
Been researching the VRP for a while on this site and others. My question / concern is could there be any effect on wet belts with constant use of VRP? I realize this isn’t a harsh solvent like Premium Blue Restore, but I often wonder if there is, or will be any effect on the belt over time causing early belt degradation.
I did email Valvoline and received a somewhat expected response along the lines of “…it means Ford’s WSS-M2C961-A1 spec and therefore is safe for use.” This was specifically regarding Ford’s change to the oil pump driven belt in the F150 5.0 (which I own). I know 2.7’s have been using them for a while now but VRP is just now coming on the scene.
I’m curious as to the opinions from the site Wizards/Elders (lol) like @OVERKILL and
@MolaKule, as well as others with a tremendous amount of oil chemistry knowledge.
I keep thinking “for every action…equal and opposite..” and I know that’s Newton’s third law of motion and doesn’t apply here, but could the synergy of combined additives, that is doing an exceptional job at cleaning deposits, over the long term cause a negative reaction to the belt?
Thanks.

The concern with PBR is the high volume of esters, which could have an effect on elastomers. This isn't a concern with VRP, since, from a base oil perspective, it's just a regular oil. It's one of the additives that (inadvertently) was discovered to provide some cleaning capabilities in the ring pack area. I'd use it without concern.

Thanks @OVERKILL , I appreciate it.
Based on everything I’ve read so far, I’ve concluded it should be safe.
It’s the skeptic in me…the “too good to be true”. Add the fact that I have a belt driven oil pump now, and it’s been a festering thought because I may elect to use this oil long term.
Again, thanks for your input
