Great video. I worked in the Cummins R&D group that Roger England lead. I was the Cummins lead scientist for Cummins Premium Blue Restore. Valvoline just blended for us after we formulated the product with their R&D scientists. The ISX 15L ( not ISB ) engine was our test mule and the requirement was to remove as close to 100% of deposits on high mileage HD diesel engines. I achieved 96% on first run on a used ISX with 1,000,000 miles on it at Jamestown NY HD plant in 2014.
Roger left Cummins not long after that. His predecessor Shawn Whitaker left Cummins for Chevron HD lubes in 2013 and I worked on low no ZDTP lubes with him. See a pattern!

I was mentored and taught by Don Carver when I was a US Navy Helo crewman and Swimmer in the late 1970’s when Roger England was a custodian at Cummins R&D center. No S-H-I-T ! Two Indiana poor boys working our way up the chain.
The Iranians took our embassy in 1979 in Tehran and my tribological career was put on hold to go smack down the Mullahs gunboat navy.

Roger needs to let Tim Caudill speak more, he’s smart and has probably 50 years test cell experience ! Roger is a VP now at Valvoline and good for him.
Thanks for sharing.

Proud of this gem from

my career.

If I had to guess what the Mumbai Valvo lab synthesized it’s a version of this unique cleaner. Probably using as a multifunctional additive too.

Awesome! Thanks for sharing that.

If I heard correctly (from the video), polar esters are good at keeping/mitigating piston deposits at bay. However, Roger said this oil actually goes even further.

What's kind of interesting though is in the beginning, they mention how well the original could clean. So does it depend then on the ester type and quantity?

The original IN MY OPINION was formulated to have base oils remove the carbon deposits around ring lands fast! Why? Because I was tasked with the impossible and the mechanical engineers at Cummins wanted me to fail as a chem engineer. I used exotic concoction of base oils not additives. We threw a CK4 add pack in just to meet specs for HD diesels. Also formulated it as a 0w-35 but we called it 10w-30 because every new engine in that time was spec’ing that for efficiency and cooling reasons. Even Grumpy Bear was impressed with the product. Note my original formulation was cut and cheapened after I departed because it was so expensive. Valvoline was a BLENDER and looks like Roger got Mumbai to synthesize my original recipe albeit less aggressive via a constituent additive that does not show up in normal testing.

The original was a lubricating solvent with such a high flash point it would not volatize off. I used experience from my aerospace tribology work in military and airlines to develop the right mix. The base oils also acted as dispersants and surfactants.

I was teamed with a certified engine rater from Valvoline on initial testing at Jamestown and he was shocked when we tore down the million mile ISX and restored it to like new cleanliness inside. We did change the oil filter during the non stop destruction of engine test cell cycle and we used emissions readings, blowby readings and constant oil analysis draws.

BTW the flushing oil between oils tested in a given test cell engine is what pros do. The one off oil analysis and mixing we see here by some is not good science but science costs $$$$.

I wonder then if oils like Amsoil SS or HPL could clean as well as this Restore & Protect (current version not the older). When Valvoline says they know of no other oil that can do this, I suppose they are referring to your off the shelf oils.

However, Amsoil SS and even HPL likely don't contain nearly as much high solvency ester as the original Restore & Protect that you were involved with formulating. So maybe they can't clean as well as some have suggested?

Thank you for your service customboss.

Most engine oil formulas including Amsoil etc are historically keep clean. Not deep clean. Amsoil in past 3 or so years is making an effort at cleaning.

HPL is new brand and I’m brain dead from dementia from TBI in military so no more deep testing for me.

So it seems from what you’ve shared and Grumpy tested HPL can clean.

Redline was a very good cleaning oil before they went majority PAO. They just overkill additives IMHO.

The diester based oil that I can’t remember the brand name was a very good solvent.

The key question is what do you want to clean? Remember in chemistry like removes like. The carbon deposits for a particular engine piston ring system is mostly fuel related. Not just engine oil blowby.

Finally to answer your question no. Restore and Protect is formulated to clean constantly.

Good points. I wonder if they're using alkylated naphthalene in this new R&P oil.

Not as we might think of from XOM. Most likely some form of a chemistry synthesized from napthenics.

I think it's fair to say at this point that this oil is using some novel ingredient, and it actually does work. If Roger's words are to be taken as is, it works even better than the higher ester based oils for cleaning.

Yes over time because they didn’t want to overload oil filters like we did with original CPB Restore.
