Wow, that's wild! Are you going to keep running the VRP for a a few OCI's at least?

Yeah, that’s the plan. My family member that drives it now doesn’t put a ton of miles on a year, so it will probably be a while before I get an update. I’ll likely change the filter mid-interval this time to be safe.

If that's accurate (5K OCI's with conventional) then it underscores how that strategy, prescribed by many on here, can utterly fail at keeping an engine clean.
Devil's advocate: did the build-up result in quantifiable performance issues?
A lot of the blanket or one size fits all statements often written here can get some people in trouble. Statements from back in the day like a good conventional oil can go 5K miles, or a good synthetic oil can go 10K miles, IMO for many of us that's looking for trouble.

Good question. I'd assume if it was put on a dyno, it would be down on power, but maybe @YotaGearhead can let us know if there were any observed issues with the engine.

Based on my 15 years in the industry servicing Toyotas, 5k intervals on conventional doesn’t typically pose a problem (for Toyota at least) aside from those exceptions for vehicles that fall under “severe” conditions. In this instance, the lack of crankcase ventilation flow caused a lot of buildup that is not typical for these engines. I agree though that some manufacturer’s intervals seem stretched under some conditions and are not a “one interval fits all” for all usage scenarios.

The buildup had no ill effects on power or performance other than some oil consumption which I’d suspect is caused from carbon deposits in the oil control rings. That was the primary reason for trying out R&P.

That makes sense, that's the area R&P targets, and is a logical motivation to try the product.
Another VRP win. Thanks for sharing again. Probably wouldn’t hurt to run that indefinitely.
I’m not surprised. I see a lot of good synthetics here still resulting in carbon buildup, much less doing any actual cleaning.
See Overkill’s results with HPL after M1 EP, a forum favorite, at good intervals. VRP is a truly revolutionary product.
That’s for the Cummins Restore product, I think.

Just curious, why do you run Amsoil SS at 5k intervals? Is your engine GDI? Known for burning oil? Earnest question. (Personally, in my view, if you're going to the trouble to get dirty and do an oil change yourself, I can see the argument to use a boutique. Doing it yourself with Amsoil is still cheaper than a dealer change.)
I'm probably going to switch to VRP or M1 next. SS every 5k is certainly overkill.
VRP and M1 ESP are really hard to beat.
You can even drop down to Quaker State Euro 5W-40 for $23 a jug and still get the MB 229.5 cert. Pretty hard value proposition to beat IMHO. I think I have a little fuel dilution from lots of short tripping, especially in the winter when we don't really get out on the highway a lot (no chance to burn it off), so going up to a 40 weight is appealing.
I'll update that a 2007 Rav4 2.4L that has been in the extended family since new is now down to less than a pint of consumption in 5,000 oci. Prior to Berrymans B12 chemtool piston soak and 3 oil changes of VRP it was 4+ quarts in 5,000 oci. Well done Valvoline, Berrymans. Let's take this Toyota closerto it's true longevity potential. Only 110k or so on the odometer.
