Bought some today at Walmart (about to start my 3rd OCI with it) and noticed the label is slightly different on this one; read that the SDS changed slightly too

hmm i thought it always looked like that ?
I don't recall the gold background part....maybe I'm wrong.
Is that API SQ?

Here is one that I bought a few months ago:
Ok so the same. I guess I had a false memory on the previous purchase
What do you believe the practical OCI limit is to maximize VR&P cleaning additives before they become depleted ? We already know some vehicle owners manuals recommend outlandish OCI’s (7,500+ miles) which may add to sludge / deposits issues . I believe using the severe service OCI for the engine - which usually is 3,750 miles and up to 1 year of the oil in service with synthetic oil . *Why extend an OCI with VR&P and risk it adding it’s own layer of new combustion and other deposits because you ran it too long ? Therefore I’m suggesting a mixed driving practical OCI limit of 4,000 miles / 6 months as being a pretty good one size fits all OCI and if 80% of driving is all interstate miles then stretching the OCI to 5,000 miles max / 6 months may be acceptable … I always hit the mileage mark of an OCI first any way before I hit the 6 month time OCI mark .
I would think about 5k of a variety of driving tops or even a bit less if engine is dirty looking through fill hole ( of a viscosity of your choice or look at owner's manual) , and make sure you install a new filter, as in a high capacity one & run a decent fuel.injector before you change oil about one tank full, also check / clean your PVC valve or just get a new one.

I think the general consensus on here is that VRP might start to lose some of its cleaning ability once you get beyond 5k, although it would be nice to have some scientific evidence of that. My first interval with it was around 5.5k and I’m almost at 6k on my current run and will be changing it next week sometime. For my third and final run I will do about 6k again.
So , keeping an OCI 5K miles or less with VR&P would seem to ensure adequate active cleaning ingredients (unless extreme short tripping) where then 3,500 to 4,000 mile OCI’s may be better (that goes double for nasty GDI engines).
Next , I watched a on line video (Royalty Auto Service) reminding vehicle owners that sludge is not just a surface / visual thing with engines - it’s an internal concern especially with VVT where all the little oil openings, passage ways , etc. need to remain clean and clear for the engine VVT system to operate properly. Once a VVT becomes dirty with sludge , carbon deposits , etc. it’s expensive to fix cleaning out all the VVT oil flow passage ways with soaks , manual cleaning , etc. By keeping OCI’s with a good synthetic (VR&P) down to <5K miles / 6 months will help avoid dirty VVT operational problems .
Lastly , I’m now running VR&P in a non - oil burner and soon will be running VR&P in my Theta II 2.4L GDI oil burner to see if I can reverse the oil burning over an OCI . *Initial VR&P observations in the non - oil burner is : “Wow , this engine runs really smooth on VR&P 5W30 - right up there with old Magnatec smooth” .
That would depend on how much there is to clean, and how much oil is in the sump. I don't see a benefit in a 6 month time limit, except for very short tripped vehicles.
Good point, and that could very well be the consensus for some. I look at it this way: if I'm using a product to clean a dirty engine why would I want to extend an OCI with the cleaning product? I'd follow the directions. Odds are neglect and running oil too long created the problem in the first place, or I bought something with unknown history. Now if I was running R&P as a regular oil, I'd contact Valvoline and have them tell me their recommended interval.
They recommend the engine manufacturer interval, I thought that was clear.
OK. I haven't read their label in quite a while, nor did I re-read 116 pages of this thread.
Everything else I said remains the same.OK. I haven't read their label in quite a while, nor did I re-read 116 pages of this thread.
Haha I see. For me that's a very clear recommendation, and one that makes sense but a lot of people want to get a fixed number from Valvoline.

A fixed number would be good because if they know from their testing that the cleaning ability is depleted past a certain mileage then why would they want people running it a lot longer? If they say change it at a maximum of 5k they can sell more oil to people who might otherwise follow the oil life monitor and push VRP to 6-10k intervals instead.
And I have said in the past that I wasn’t sure if this oil is really up to the task of doing 10k intervals and that is what my Civic’s oil life monitor gives me for my intervals. So that was one of the reasons why I decided VRP is not a long term option for me. But if Valvoline ever did come out and say that it’s formulated to go 10k or 15k, then that changes things. I guess we’ve all gotten used to a lot of our favorite oils having mileage ratings posted on them. Even if few of us go as far as they rate it for, it gives people piece of mind knowing that the oil was formulated for extended intervals.

On the other hand, is the "Varnish" a protective coating against corrosion?
