I don't see how the MDS system components being more or less clean would have any impact on how frequently it engages, which is determined by the ECM, based primarily on load. If something was "plugged up", this doesn't alter the parameters used to engage/disengage it, though I could see it making the engagement/disengagement smoother, like I found with HPL.
Maybe HPL has a super low coefficient of friction.

Probably so in a case like the Hyundai/Kia 1.6 gamma engines. Loads and loads of them plugged up the piston rings with 5K oil changes. I can personally vouch for that. I don’t even know if 3K would compensate for a bad design.
As best as I can tell there are now only two UOAs posted for VRP. Both were of the 5w-30 flavor and both had had fallen below grade after a relatively short OCI. As the saying goes, "Once is chance, twice is coincidence and the third time it's a pattern." The more colorful version of that is that the third time is the result of enemy action.
TIA Were they in DI engines with fuel dilution, or engines that had fuel dilution? I don't remember the UOA reports. In any event when cleaning up an engine, shorter OCIs IMO is always a good idea.
The VRP oils are still API SP fuel economy grades so shear stability will not be on par with the Euro and boutique 5w30's. However if it's fuel dilution related, all oils will have this issue.

Running the infamous Hyundai 2.4 L non - turbo Theta II GDI engine here . I have used Mobil and SOPUS synthrtic 5W30 oils all run at severe service interval OCI ‘s (3750 miles / 6 months with Fram Ultra filter) and yet I have an oil consumption issue with this engine . Current fill is M1 5W30 EP plus 16 oz. Rislone engine cleaner . I’ll consider Valvoline R&P 5W30 or Frankenstein M1 5W30 EP with M1 5W40 Euro synthetic oil to see if I can cut back on the oil burning through cleaner rings and / or thicker weight oil .
Yup, as you can see in my signature, my son is running one of these engines also. He's at 55K right now and so far, so good. I have been changing his oil every 4K. So far, mostly Napa, Supertech and Havoline.

Hths of 3.24 for the 5w30. Pretty good for API SP-RC
What's the hths for the 0w-20 version?

Just out of curiosity do you use TT fuel?

I only watched this video because you posted it here as I avoid these types of videos like the plague, and yes he's a little off the deep end but that won't stop him from posting "THIS OIL FIXED MY HEMI" in all caps without understanding how the system works.
Did he even listen to the video he recorded, because I heard MDS kicking in/out every few seconds so I'm wondering how bad it must have been in the past.
Yes , always … 87 octane .

I have seen the lack of TT fuel claimed to contribute to rings sticking, causing oil consumption problems
You have the oil covered, and the fuel covered. I'm guessing there's no real solution to that engine design.
4.0l v6
My "Dads 1997 Chevy PU" next change is in 1500 miles. It has 178,500 miles on the 4.3L V6. I am going to commit to doing the next four 5000 mile changes with Valvoline Restore & Protect. It looks like an outstanding oil and it does not cost $15 a qt.
