What is or will be your planned OCI using VR&P ? I believe that first usage of VR&P will be less than 5K miles (depends on engine condition) . Subsequent OCI’s TBD in terms of mileage but no more than 5K miles / 6 months OCI. I’m not sure what the point would be running VR&P for longer OCI’s (i.e. going off an OLM for 10K miles) ? Seems to me that 10K mile OCI’s may contribute to having to use VR&P in the first place.

Olea jacta est.
If it was overfilled it would foam.
You might not have much to clean
I went through a phase where I pushed my OCIs to 10K, 12K, even over 13K once with M1-EP. Got a UOA on that one and it didn’t look good. It’s posted on here.
I’ve since settled on 8K or less.
I should get another UOA to see if it’s settled down because that was years ago.
It's the same youtuber who's video someone posted in this thread that may show varnish cleaning and that was also a video of a video of a borescope. But you're right it may not be foam but maybe frog eggs. Who's to say what's going on as very few people scope up through the drain hole. Maybe it's common if you looked, maybe this car was overfilled, maybe a reaction with residual oil, maybe a bad PCV, maybe a bad head gasket, etc, etc. Like this forum the video is anecdotal.
I hope you’re doing that for an Engine that’s already clean. My experience with VRP on a dirty, very used engine is that 5k is much too far for a first interval. At least for the filter.

In oleum veritas.
I am planning on switching over to VRP on all three of my cars for their next changes because they are all over 100k miles and I feel left out of the club. Are 3000 mile OCIs a waste of money with VRP? Only my Camry burns oil (and she is probably spotless other than the rings after HPL EC, BG EPR, and B12 soaks), but none of them get driven extensively throughout the year since the wife got a company car (Camry ~6,000, Civic ~3,500, Pilot ~8,000).
I'm about 1000 miles into the change on my F-350. It's already BLACK. This was an engine that I manually de-sludged when I was changing a head gasket due to it corroding and leaking oil. The NAPA conventional that was in there immediately following the engine work didn't really turn that black. I'm not a tribologist, I really don't know what it's supposed to be doing or supposedly doing, but it seems to be cleaning something.
It started leaking oil out of the head again over the winter before the VRP. Seemed to be back to adding a quart every 150 or 200 miles or so. I assumed it was all out of the head again ... prior to doing the head gasket, I was putting a quart in every 75 miles.
I put in VRP and went through 2 quarts pretty quickly. 550 miles ago was the last time I added in a quart.
The oil level is definitely still going down. But I'm on track to get 800 miles before I have to add another quart. It's still marking it's territory but it seems less. I'm wondering if some of it was internal to the engine too?
It's done nothing for the horrendous piston slap this old worn out engine experiences

I’d run it for the whole interval. Maybe just change the filter half way through and inspect it.
Does the Camry still burn oil after HPL? Did it get better?
Thread 'HPL EC treatment started. 2007 Camry 2AZ-FE 153k consumption.' https://bobistheoilguy.com/forums/t...ed-2007-camry-2az-fe-153k-consumption.374589/
Is the summary of 9 pages of posts that it didn't work but the B12 piston soak did?
That's it. However, mine was a pretty bad case at 1 quart per 350 miles. I ran 1 quart HPL EC and 3.5 quarts of oil for... three or four OCIs?... and it didn't move the needle. I also ran at least 2 cans of BG EPR through her that also did nothing. I finally threw the kitchen sink at her with a five day, five bottle B12 soak and it worked wonders (relatively speaking).
The problem with the 2AZ-FE is both low-tension rings and that the oil return holes in the pistons were bored too small. Once those holes clog up (which, as sure as the Sun will rise in the East, they will), the rings are doomed. Toyota had a program to replace the pistons at one point but I missed out on it. I don't know if the B12 cleaned those holes out (probably not) but it definitely freed up the rings. Prior to the soak she was difficult to start in the morning because so much oil was getting past the rings overnight once she cooled down that she wasn't holding compression well for that first start. After the soak she fires up quick as a bunny. I am planning on doing another multi-day/bottle soak again soon and then switching over to VRP to see if it keeps the consumption from coming back.
Either way, it is a helluva lot cheaper and easier than replacing the pistons on an 18 year old engine.
Nice work on saving that engine.
Thanks for the summary. I wish BITOG had a wiki feature so you could just add that to the top haha.
