Do you have UOAs to back this up?
Valvoline Restore & Protect

What kind of vehicle?
Hmmmm, I'll keep it in for the shorter range then - 3 to 4K miles - and do the 3 to 4 intervals that way. HPL after this because my goal is to be able to take my engine apart and use various pieces as a dish to eat my dinner off of.
Anyone have any current updates while using this product? Thank You
I'll be starting a 4 OCI run in the 2020 ram hemi in the next month or 2 but its not even installed yet.
2014 Subaru Legacy, FB25 6MT, 95000 miles
2500+ miles into the first OCI with VRP 0W-20. Previously used Kirkland 0W-20 (mostly).
Avg mpg is up from 23mpg to 26mpg according to the trip computer which was zeroed at the oil change. The 2500 miles is a rough 50/50 split between town and highway. I also zero it (trip B) for highway trips and have seen 35+ mpg which is respectable but I've nothing to compare to pre-VRP.

My bald spot is smaller
My A1C is down
After 4 OCIs I'm hoping for a bigger bulge in my pants
Kool-Aid anyone ?

No. I do not have UOAs but just something I noticed draining the oil cold. It was noticeable enough in my applications for me to stop the runs at 5k. YMMV
I don't doubt that it can't but my comment was about your last statement.
the car manufacturer specced oil change interval.
it's 4x3000 miles in a 3k oci car, 4x10k in a 10k oci car.... I don't see how that's confusing. or follow the OLM. Or do people don't know when they should change the oil?

It’s confusing because it should not take 4 intervals to clean up the engine if you are doing 10k intervals. Why would one engine need 40,000 miles to clean up and another only 12,000 miles just because the manufacturer has a different OCI? Think about that one.
Obviously a very dirty engine is going to take longer but Valvoline must have a rough idea about how long it typically takes in total miles. And I doubt that too many engines would take 40,000 miles to clean up. If they were that dirty they probably wouldn’t even still be running.
why wouldn't it take 10k? it only had the same amount of cleaning agent run through it as another car with the same sump capacity. The more stuff is dissolved, the lower the capacity to dissolve more becomes.
what it takes is about 4 oci, or 4 rinses....

But you are saying that it will take 40k for cars that have a 10k OCI and only 12k for engines that have a 3k OCI. That’s the part that doesn’t make sense.
I keep mine at 3-4k miles as my car started burning oil around 4k miles. It did not burn oil prior to using it, not using it for stuck rings. I was doing 5k mile oci with various fs oils. Others have commented roughly the same in here so I keep mine under 4k. I had visible blue smoke from the exhaust and 4 years ago when I bought the car it did not have this even though it was burning ~2qts per 5k mile oci.
I would keep an eye on the levels and just see how it goes but I wouldn't push it beyond 5k regardless.
It takes 4 oci I said. whatever oci is. Maybe a 10k oci on regular oils doesn't make sense anyway.
I wouldn't even pin myself down on 4 oci. It takes however long it takes. Since I'm not stripping the engine afterwards, I don't care if it's 100% clean or 30% clean anyway. I care that the rings are free and stay free. So I'd use it until I stopped seeing improvements, like reduced oil consumption or reduced varnish deposits.
Think it really comes down to Valvoline not trying to over ride the manufacture's recommended OCI service schedule. Once they do that, they become liable. So it's easier and safer to just say follow the OM for the OCI schedule, and recommended using VRP for 4 OCIs to ensure it's had enough time to do it's job. That covers OM recommended short and long OCIs.

Which last statement? VRP should also as you said "clean them as they are deposited" - that's the "Protect" part. My main point was VRP will probably do a better cleaning up of an already dirty engine faster and better than Mobil 1 which doesn't claim to do what VRP claims to do wrt to engine cleaning deposits already in the engine.

I think Valvoline should have just said that it can take up to 20,000 miles to get an engine close to 100% clean and not even mention the OCI. In reality I think a lot of people are going to be in the 3-5k range anyway.
