For the Rislone oil additive user crowd - how often are you using ? I started using a bottle every third synthetic oil OCI but with a GDI engine dealing with moderate oil consumption I may move this Rislone schedule up to using every other OCI and use Rislone in between as a top off oil to clean and restore those ring packs . *Readers may say “why don’t you just use Valvoline Restore and Protect oil” ? Because Valvoline Restore and Protect doesn’t make a 30 weight oil with a HTHS of 3.5 as does M1 0W30 ESP is why .

Which of your vehicles is the oil burner?
Understandable. But running vrp on it's own for just a run or two very likely won't hurt anything especially if you're not driving it hard. There are some turbo gdi engines running on 20 grade.
I'd swap a quart of vrp out for some castrol 10w-60 available at parts stores if I wanted to thicken it some. Valvoline's standard 5w30's are known to be 3.1-3.3 hths depending on the variant. A quart of 5.1 hths oil will help some. A shame Valvoline didn't publish the hths for vrp.

Rislone is roughly a 20-grade oil, so you are diluting your 0w30 out of grade with the Rislone. I'd either run the VRP at 5w30 or add the Rislone to a 40-grade oil if you want to stay within a 30 grade. Some run Rislone with every oil change; it is up to you.
Have you noticed any results with Rislone?
If you have Oil Consumption it sounds like you should be using this Rislone every OCI.
If you have been using a Motor Oil with a HTHS of 3.5 and you have Oil Consumption issues, the HTHS number means nothing, give the Valvoline Restore and Protect a shot.
I do believe the Mobil 1 0W30 ESP has a HTHS Number of 3.5
I do believe HPL has an Engine Cleaner that is a 30 Weight, maybe 5w30
Think about it, if Rislone really cleaned up Ring Packs, then why all the talk about Valvoline Restore and Protect?

Could be people are not aware of Rislone ? I don’t expect Rislone to stop oil consumption in a GDI engine but watching to see if it slows it down any .

I dont think that Rislone will do much for that engine. It's on its way out. But if you want to try, I would still go with the Valvoline Restore and Protect over the Rislone, or even HPL's Engine cleaner (or even the PCMO) Nothing against Rislone, it's been around forever, but I don't believe it is as strong as the others. If you think it's a ring pack issue, go with one of the others. You won't be putting the others in every OCI, either.
Rislone does work, just slower. Once I did a piston soak on my Honda I ran Rislone, HPL EC30 and Gumout Multisystem Tune Up in it to continue cleaning and stop the rest of the burning. It took 2 years of patience but it finally subsided. If VRP was out I would have just ran it. Good luck and if I as trying to cure a consumption with Rislone I'd run it every oil change.
You could get some HPL EC40 and add 1/2 quart at each change or substitute the full 1 qt in place of whatever you are using currently. That will get you a bit thicker plus the EC benefits. The BITOG discount might break even with shipping vs. the Rislone.
I've never tried the Rislone, I have used EC30. At least one user stated that they double up on the Rislone bottles when trying to clean stuff. I think it was @Retirednow IIRC.
Feeling crazy try the VRP in 5w30 and send a sample off at the end. At least you will know what YOUR motor is doing for shear and viscosity as well as fuel dilution etc depending where you send it. My experience in last samples was that Blackstone and Oil Analyzers are way off on FD from each other. OA uses the GC so I trust that more.
You can search some of my posts with pictures of the HPL and PP Euro-L in my daughters CRV slowly working to clean up carbon from low flow baffle plate area. That should be doing the same for ring areas. Hers doesn't burn oil and hasn't with 241k on it. I did I think 2 (maybe 3) rounds of EC30 in it. I now use one quart of regular HPL PCMO 5w30 in place of whatever oil I'm using in 3 cars currently. You could the same with a 5W-40 or other.
I'm not here to push the HPL vs others debate. If Rislone works for you then all is well and continue on. I do know that my use of HPL put things in my filters I had never seen before and that was with all the BG EPR, Gunk Motor Medic and other liquid dump and flush versions. I've cut my filters apart for many years so doing it for this was nothing new, just the junk was.
Having the GDI I totally understand wanting thicker oil with the shear etc. That is why my recommended 0W-20 Pilot is now on 5w30 which got bumped as a result of testing.

Two bottles in the Audi S3 and Falcon (Barra) every oci. One bottle in the Suzuki Swift Sport (smaller sump).
the 16.9 ounce bottles or the 32 ounce or what ever the liter equivalent of that is?

500ml per bottle so a litre total. 16.907 U.S fluid oz per bottle.
I believe some time back Rislone was mentioned as a 30 weight from a very respected member on here. I will be using it in the wifes Subaru 2.5L next oil change coming up. I have used it in the past for years now on higher mileage engines to help with cleaning/conditioning as mentioned on Rislones bottle. I see no problems using every or every other oil change. Speaking with Dave from HPL -- I used the HP EC30 engine cleaner first per instructions and a bottle of Rislone every oil change after on an old 2004 Ford Taurus 3.0L OHV Vulcan engine with 190K at the time and he said it sounded like a sound plan. Either the HPL EC or the Rislone resolved a lifter/valve tick on the Vulcan.
I think you said that the HPL is not available shipping or prohibitive due cost of shipping if it is. if it was decently available would you rather use 1qt of EC30 or EC40 instead of 2 bottles of Rislone?
If @ChrisD46 did the 2 Rislone's as you do, looking at Walmart while I'm there would be about $16 (~$8/bottle) so basically the same per quart as the HPL EC's.
I don't think I have seen any tests for any carbon cleaning comparisons on Rislone vs. HPL EC or their regular oils. Not sure exactly how one would test that individually. I know Rislone has been on the shelves for many years when I was in stores. Some people I recall always using it because it worked for them. That again is possibly a function of just general more regular maintenance as compared to others.
Anecdotal - I took out my John Deere riding mower yesterday to mulch some leaves. It had been sitting for at least 1 month and last oil change it got VRP. I always check the oil before I start it. The oil on dipstick had some definite black streaking in it that I had not seen before. I'll need to make note to take a picture next time. It looked clear afterward so maybe whatever stuff is now caught in the filter.

Really
maybe but unsure of EC cost. Rislone 4102 is readily available. We order the six pack
