Which oil cleans more: HPL or Valvoline Restore and Protect?

Hasn't been determined. R&P is a new technology where as HPL is using the traditional high solvency/detergent way which is proven. If you're using HPL you shouldn't have any carbon ring build up.

R&P is also limited in terms of viscosity grades. It's also not as long drain capable as HPL.

R&P has a unique chemistry that even impressed Dr. Warholic who worked for Infineum for over 16 years.

Cleaning piston deposits is not an easy task. Valvoline had to really make an oil with substantial group V (50%) for it to be able to remove piston deposits. Cleaning sludge and other carbon is not the same as piston deposits, something that most get wrong.

You'd have to run a test and tear down the engine and look at pistons, which no one is going to do.

Valvoline does give you this:

Ask HPL to provide pictures representing their cleaning capability from a comparable study. I'm relatively sure that they won't be able to do it.

I'm sure they'd be able to do the study, whether they'd be motivated to do so is really the question. They have access to tons of tear-down data from their fleet and racing partnerships, but they would not have organically produced results of cleaning up the ring land area that would be statistically rigorous enough and/or comparable to a specifically crafted version of an existing ASTM sequence.

So, what would be their motivation to spend the money on reproducing this test? Their product isn't sold in brick & mortar stores like Walmart where it would compete for shelf space with VRP and Mobil 1 and a similar claim could increase sales volume. Their primary customer bases are industrial, race and fleet use, and those aren't folks that, by and large, are looking to clean coked-up ring lands.

HPL's "schtick" isn't cleaning - folks here are obsessed with it. It's a positive byproduct of how their oils are formulated/ingrediants. Use HPL for longer OCIs w/low deposit formation and/or where you need an oil to hold up to abuse.

I’m using it because I don’t mind paying more for a quality product and seeing results instead of marketing and advertising.

That is all
 
If one oil could, I think it would be HPL IMO. Piston deposits are much different than varnish/sludge so I couldn't say with confidence what oils could clean up piston rings though. With the amount of solvency in oils like HPL, Amsoil SS, Torco, RL my guess is over time they could to some degree. If I read into what Dr. Warholic said in that article, it makes me skeptical too. More importantly is to run oil that runs clean even when beat up a bit.

Unless you use the other products, how do you know it's just marketing?
Marketing sells. Plain and simple. I don’t care that HPL doesn’t advertise either.

As for results; the oil is getting real dark over the interval. We’ve been down this Q&A about cleaning with HPL before so I’m not answering the same repetitive questions over and over.

All oils get dark over the interval. When folks make claims here, they need to back it up - that's the BITOG way. I like HPL and run it, any claims that I make here about using it are backed by what data I can gather (UOAs). Saying you choose HPL over the Valvoline product b/c you desire results not marketing has no backing. Maybe the Valvoline product works great and gives you the same results (maybe it gives better results!), who knows. I'll keep asking if you keep making statements like this. Why not "I like HPL and that's why I use it."?

Great question :unsure:that is impossible for me (not anywhere near close to a chemical engineer nor a professionally trained lubrication specialist) to answer. You I am certain likely have more knowledge based on your driving passion history + experiences at the tracks than others.

Most of us , others.... older drivers have likely have used near everything out there at one time or another and finally picked favorites for who knows what host of reasons.

I would bet majority of us have never had engine failures either over the years and thru the use of all those products available.
No one can deny that the products the oil industry has available to us all these days is leaps and bounds superior to what many of us started out driving with in the 60s and 70s. Great news for all of us except for the costs like a lot of things.

So, unless we do controlled research and all sorts of testing and studies ..... how on earth does one choose? Let alone who says what is THE ONE? ;)

So, what are you using HPL?!?!
 
I am really interested in one of these cleaning oils for something I have been working on for some time and it is finally almost ready to see the road in the spring. This is the one I am going with. Once it is cleaned up it will get Mobil 1 0w40 3K OCI.
Edit: I know someone that has a few gal of this stuff I can get but it seems unavailable otherwise.

Valvoline Modern Engine got very dark in just 2k … That’s in a well maintained Pentastar with only 35k - doubt it was a dirty engine …
 
Why not use both: Valvoline R&P + 1 quart HPL EC 30.
This "may" be a bad idea. "Sometimes" the additive packages of different oils don't chemically get along.

The chemical engineers at these companies did a lot of work to figure out the concentration of each additive in the add package of these oils, and backed that up with spending a significant amount of money and time actually testing these oils by running engines using them.

People that mix oils are basicly throwing all this research work out the window and taking an unknown shot in the dark by mixing something up.

Lake Speed has gone into this on his YouTube videos. It's a really bad idea. Just don't mix oils.

Formulating good motor oil may not be rocket science, but it does require very intelligent people who are very knowledgeable about all the additives and how they interact with each other.
