Did you stick with HPL after that first one? Was there oil consumption before, during or after use?This is what happened the first OCI running HPL in an Elantra we once owned.
Will HPL PCMO help my oil consumption?

It was sold soon after that oil change. It didn't use oil.
My truck burned almost a full quart on my first 1 year/12k interval. But that included some heavy hauling on the highway and an alleged late night “cannon ball” inspired highway run with my wife playing lookout… her exact words were “I want to be back at the place we’re staying at 3 hours ago, make that happen I’ll watch for cops.” 
From more reading I suppose if I did try HPL and my car used oil there's a strong possibility it's not the rings but could be scoring on the cylinder walls or the PCV system just sucks (pun intended)
Rather than continuing to wonder why not give it a try?
We don’t know if HPL can clean piston deposits. Carbon in filter could just be from the high level detergents cleaning sludge type carbon. HPL has an extremely high SA level with a lot of metallic detergents (mg/Ca). Ring deposits are a different animal. Plus we don’t know how much AN or ester HPL has. It takes a very high level of AN for it to work as a cleaner. Same with POE. Take a look at the patent for VPBR.
I argue that HPL can clean carbon deposits from piston ring lands and grooves. Go back and look at the the pictures of filters and internals from my Durango. The inside of the engine is spotless, but we see carbon trapped in the oil filter. The only place the carbon could have come from is the pistons and that makes sense because the pistons are the hottest component the oil is exposed to.
I would ask admin to change your title a bit in your post. It is misleading......IMO. It leads one to think that HPL is the source of your consumption.
HPL could help with the consumption I suppose, you will have to try and see.
I definitely will man! After I've run VRP through at least two more changes (4 total). That will be almost 20k miles with the stuff.
If it's not clear by now, I'll say this (for everyone), I'm not meticulously and scientifically studying whether or not VRP does what it claims, let alone anything better than some other oil, including and especially oil consumption (and I fully understand Valvoline doesn't claim that the VRP solves that problem).
Other people have done a better job at that. I'm after one thing and one thing only, reducing or eliminating oil consumption. Can oil do that? Can VRP do that? I think there's a lot of anecdotes both for and against VRP about whether or not it can. But It seemed enticing to me, promising even, when I first saw ads for it. What do I have to lose? Once I put a jug in I knew I was going to stick with it a minimum of four oil changes to see if it does anything. It doesn't effect me at all if someone likes it or not or believes it works or not.
It's the same with HPL. And I do hope it works, I want it to work so bad, just as much as I want the VRP to work. I once tried Amsoil SS in hopes it would help but it did not. Between trying Amsoil SS and now the VRP, my hopes and expectations for the HPL are high. But, also the price of HPL compels me to hold it to a much higher standard. If consumption is too much when using HPL, I'm switching back to VRP no questions asked, because I know I can afford it to feed my oil guzzler of a car.

I thought I had a "?" In there, as in asking the community if anyone knows of HPL being used in an car with oil consumption and it did not have any effect on the rate of consumption.

Title edited. Previous title implied there was oil consumption with HPL. What you thought was a clear title, was, actually, ambiguous.
She's a keeper. I'm jealous....... an alleged late night “cannon ball” inspired highway run with my wife playing lookout… her exact words were “I want to be back at the place we’re staying at 3 hours ago, make that happen I’ll watch for cops.”

What sludge type carbon do you think was present in my RAM 1500 after a short life of OLM intervals on M1 EP?

Same with my RAM 1500 and my SRT.
I've been running various grades of HPL pcmo in my 140,000 mile 2018 Subaru Forester FB25 manual transmission (a combo known for oil consumption even at very low mileage) for the past 60,000 miles.
Oil consumption appears to be increasing in time. Initially it was pretty consistent 1 quart per 6-7,000 miles at 80,000 miles. Now about 1 quart per 4,000 at 140,000 miles. Perhaps my engine would have benefitted most from using HPL sooner than 80,000 miles odometer. At first I was unsure if related to pcv system, but now after some time I believe it is rings as well. (Wear? Not much carbon in filters..) if consumption decreases I'll be sure to share.
I service many subarus and have seen a reduction in oil consumption by switching to HPL, up to a certain rate of consumption. It is possible my fb25 was just past the point it needed to be in that regard. Most notable has been a friends FB20 6mt crosstrek which was switched to HPL at 25,000 miles. It had consumed one quart per 7,000 from new and that dropped to .25 quart every 6,000 miles and has stayed at that rate ever since.
I would like to see how well a brand new engine holds up on HPL, where the odds could truly be in favor of the oil used.

Thank you for sharing. I think your experience will truly help me temper my expectations when, not if, I give HPL a try.
Im thinking oil consumption is slowly starting to improve in my 2.4L, but nowhere near you or your friend's results with the HPL. And I'm quite certain, just as others have pointed out, there's a limit to how much I can reduce consumption by doing things to clean carbon deposits (such as what would be causing piston rings to stick).
Unfortunately for me, my problem is likely much deeper. Piston ring wear, cylinder walls, etc. Short of an engine rebuild, it may very well continue to consume oil. And as much as I would love to eliminate the consumption altogether, I'd honestly just be happy with reducing the amount of oil I have to add between a relatively short 5k miles OCI even a little.
Just today, I thought "maybe I should just embrace it. My car drinks oil, it's an oil guzzler" and get a "gas guzzler" window decal but for oil. Its a clever twist on a funny meme and a bit of an inside joke. IYKYK, y'know?
If not for anything else, it will bring you peace of mind. Good luck
It could very well be that HPL can remove/clean/dissolve piston deposits. Certainly possible.
Can't hurt to try it. It can be tricky to identify the cause of oil consumption. Some engines consume oils that are lower in volatility, which is not what you'd expect. They're changing Noack for GF-7. Can also be the ring type and how the engine was broken in and just wear pattern in general. You may even just have to go up a grade or two.
