Is that a fact, speculation or even just hope? Because, "chemistry" without any further information is nebulous. Just asking as I have skin in the oil game as I own a DI engine equipped car and would love a mechanic-in-a-bottle fix.
A lot of the "facts" you read on forums are just speculations. Everyone has their favorite brand, or brands of lubricants and other products, and they tend to get a tad overzealous. You'll have to forgive them and realize that sometimes it's the enthusiasm in people that talks, not their common sense.
That being said,
@High Performance Lubricants is the real deal. It is an overbuilt motor oil aimed at long drain intervals, cleaning dirty engines and keeping them clean, and keeping wear down to an absolute minimum. It is very expensive to blend.
@High Performance Lubricants is an industrial company, with their main customer being fleets and the heavy industry, including the food industry. They are not a boutique blender by any means.
@High Performance Lubricants formulations are proprietary and they have never talked specifics about their formulations, other than using Group III, PAO, ANs, and Esters. Neither have they talked specifically about their customer fleets, so that right there is more speculation. They did, however, say that they have perfected their blends by analyzing lubricant data in vehicles, pickup trucks, semi trucks, etc. that stretches over 200 million miles per year.
You will be well served using their motor oil in your GDI engine as it stands up very well to fuel dilution. Their PCMO Premium Plus is blended with Star Polymers. I've seen the 0W-20 version of that stand up and keep its viscosity over 8 cSt even in horribly fuel diluting Honda TGDI engines.
I actually have a nice stash of HPL lubes and have used them over the past year. Currently I'm evaluating some Mobil 1 lubes out of curiosity, however, I will go back to HPL soon.
Finally, the formulations were created with the help of Dr. Leslie R. Rudnick. I encourage you to google his name and look him up on Amazon. He published dozens of books on lubricants and is considered to by the godfather of synthetic oils.
If in doubt, I suggest you start with their Engine Cleaner EC30. Run that for an OCI and see how it cleans up your engine. In fact, I got that running in our 2017 Hyundai Santa Fe along with Mobil 1 FS 0W-40. I'm at 4000 miles and I'm draining the oil today. If there is anything of note in the filter I will post some pictures. I'm pretty sure it loosened some deposits especially around the piston rings, as the oil is pretty dirty on the dipstick. It's a GDI engine.
