Not really. There haven't yet been any signs of cleaning on the Legend, it still has the same cold lifter tick, and my friend's CRV still seems to be burning oil at about the same rate.

If you want this oil to work better, drive the vehicle for 10+ miles per trip. One needs to get the engine and the oil up to it's proper temperature and still have several more miles to drive. Better tests of this oil are the 12+k annual travelers. If all you are doing are short-tripping your vehicles to grocery stores or schools, this ain't the oil for you.
Correct. I rarely drive any of my cars less than 20 mile round trips and a lot of my commutes are 25+ miles each way, so the oil has plenty of time to warm up. The Legend also has a large oil to coolant heat exchanger built into the oil filter housing, which should help with warmup. My friend's CRV is often used on longer trips too.
Some here regard VRP as a threat to HPL. It is a very unnerving thought to them.
The horror of it!!!!

OMG.....really? You actually think HPL Management has lost confidence because of VRP? That's hilarious!
Respectfully, I think @gfh77665 meant that some of BITOG’s HPL fans are concerned (threatened by?) a more pedestrian product that may also offer internal engine cleaning and decarbonization previously only available from high end “boutique” motor oil brands.
Exactly. Thank you.
Doesn't seem like that slight potential improvement in oil consumption on my friend's CRV was due to anything other than the additional highway usage. After 1900 miles of his normal driving since the last oil change, he added a total of 2 quarts. That works out to 950 miles per quart- right in line with the 1K mile per quart average.
It's looking like there's going to be a 3rd test though because he decided to try R&P in his mom's Camry with the infamous 2AZ-FE. For those who don't know, they are notorious for clogged/stuck rings. I'm not sure exactly how much oil hers is burning, but I'll report back once I have more information.

I'm not reading through 9 pages so forgive me if it's been answered already, but are any of these vehicles getting at least 4 oil changes with the Valvoline Restore and Protect? Because I have 5000 miles spread over two OCIs of use with the stuff in the past two months, and I'm quite certain I'll need to do another 2-3 oil changes (about 10-15k milea more) before I see any improvement, let alone noteworthy improvement in oil consumption.
This is for my 2019 Kia Sportage with the dreaded 2.4L Theta II, and sitting at 110k miles (bought used at 98k 3 months ago) it drinks a quart in 500 miles.
I think now is also a good time to state the obvious that Valvoline doesn't claim this product will do anything for oil consumption. Not to my knowledge anyway. It's a reasonable conclusion to draw, and should work. I'm interested to see how it fairs in my Kia.
MrBaum, I'm willing to do at least four oil changes whether I see improvement or not. I'm still on the first one though. There are reports of people seeing improvement during the initial OCI.
None yet. The Legend is still on its first oil change and the CRV is half way through its second. I never said nor meant to imply that the product doesn't do as advertised, I'm simply sharing the results of my testing so far.
Valvoline doesn't specifically claim a reduction in oil consumption, but since they advertise cleaner pistons and ring grooves, a reduction in oil consumption caused by carbon would be a reasonable expectation IMO. Pretty much the entire reason piston cleanliness even matters is because deposits tend to interfere with proper ring operation.
Or the rings could have rotated and no amount of cleaning will matter.
Aren't they supposed to rotate, to prevent them from being stuck in a position where the gap remains aligned with the other one?
Correct. Rings naturally rotate in use
Yeah as @The Critic said just cleaning rings won't guarantee a stop in oil consumption. My older Toyota and Hondas consumed oil when new just due to how the engine/rings were. Had nothing to do with them being clean.

The automotive repair trade like most trades is heavily influenced by mentor teaching, and training.
Some great experience has been passed down through this process.
Unfortunately this also leads to misinformation being passed down through generations of apprentices, and trainees.
When I was learning the trade in the 70s, "rings don't rotate" was common knowledge.
One of the things I've always tried to teach anyone I mentored is how important reading is, to being competent on the job.
Still learning!
But similarly, if you’ve ever held a piston in your hands with rings in place, the first thing you notice is how easy it is to grab the rings and turn them. Yes, they’re compressed when the piston is installed in the bore, but there’s nothing locking them in place and of course they’ll move around during use.
