Valvoline and any other big oil maker knows what the Noack is because they will measure it in their lab.

I didn’t state it in the following thread, but at 2 hours, my Noack estimate for it and M1 5W-30 is around 8.7%. That was before the SDS stated GTL base oils, so it may be less now.

I am curious why NOACK, or evaporation loss, is an issue in this application. What am I missing?
No, not at all. I’m saying it’s totally normal. Look at the post I responded to and the chain of replies. Someone is arguing that it wasn’t Valvoline that came up with this cleaning agent but another lab. And I’m just saying that’s normal. How it works. Valvoline probably funded the lab or contracted them to do work for them.
Who said it was an issue?
I tried to get more detailed information from Valvoline on their EP oils,they said only what was published, and also Mobil and they too were tight lipped on info. other more less common brands will give or more likely give out better detailed information on their products it seems.

Exactly. It isn't isn't that Valvoline developed the additive. They paid for it.
Sounded like it was a lab that routinely does work for Valvoline, and most likely R&P uses proprietary ingredients. So doubt other oil companies can pay and get the same additives from the same developer. Valvoline has it locked down.

Right, but there seems to be an idea on the forum from some members that Valvoline themselves, in Lexington Kentucky, is creating the additive(s). They are not.
Regardless of what lab worked with Valvoline to developed the additives, or where the development work was done, they are still proprietary additives only known by and used by Valvoline.

Yeah, that's not the "argument".
Their test labs are in Lexington Kentucky, and they do ASTM Sequence testing on the finished products, as seen in some videos. Their formulation R&D is in India. Maybe it was in Lexington Kentucky a long time ago, but not now. It sounds like Valvoline owns the lab in India.

Agreed ! I’m doing the opposite coming from my current fill of 0W30 ESP to 5W30 VRP (on deck next) .As for me, I plan on living vicariously through Glenda W.
Anxiously awaiting the results of G.W's test moving from VRP to ESP 0w-30.
If the results are as I expect, I will follow suit. Been on VRP for 3 OCI's. Likely switch to ESP. Waiting for the resulsfrom Glenda W.
I believe Valvoline was working with an Indian lab when the magic RP cleaning ingredient was discovered .
Update: Checked on these while grabbing some Gumout for the Toyota. No visible change. I’ll use this black one that’s been soaking during the next change with VRP to see what happens while in service.
I do wonder if being able to experience engine temperatures would make the results more conclusive.
It’s possible. There is a blue one on there right now. I’ll take pics of it when I do the next change here soon which will be at approx 3 months (May to Aug) and 5000 miles. I’ll install this soaked black one next so we can see what happens to it. It’s a typical hot summer here in the Texas so it’ll see some heat cycles.
