Where can I find Noack numbers for HPL car oils?

You won’t, because they don’t test for Noack. It’s not a high-reliability/repeatability test anyways. Besides, you don’t really need to worry about volatility with their oils because they use very good base oils and low/no levels of the lower-volatility VIIs.
They use a different test (the name escapes me at 5:15am) but over a 15k mile OCI my 3.5 EcoBoost didn’t use any measurable amount.

The HPL base stocks are so finely spec'd/made that the traditional NOACK testing typically cannot discern the resultant values.
Suffice it to say that they are some of the best performing oils on the market in regard to volatility resistance.

Absolutely. Likely well below that.

Can't find Calcium, Magnesium, Phosphorous, Zinc, Moly and Boron numbers either (all the BITOG add-pack favorites)
Would like to find them for the two best selling grades / viscosities (0w20 and 5w30) of each oil jug label that offers 0w20 / 5w30.
If it weren't for a few random UOAs / VOAs, at BITOG, we wouldn't have anything to compare..

I need a link to find what you have posted above, plus other typical elemental concentrations for HPL.
Thanks.

Hpl have all ingredients for low noack and high flash point, but pds show flash point of synthetic blend level,
Can anyone explain why?
Probably because they use a lot of PAO. PAO is generally better than Group III or GTL base oils in terms of volatility and pour point, but the lighter PAO base stocks used for 0W and 5W oils tend to have a lower flashpoint. The thicker PAO base oils have similar flashpoints to the others.
I'm late to this party, but.... HPL doesn't use Noack. They use TGA for volatility, a more preferred method. The procedure for using TGA for volatility was actually written by their technical director, Dr. Rudnick. They did have their entry level PCMO 10W-20 sent off for Noack on request. It was 3.4%.
Is HPL running a modified ASTM D6375? D6375 is the standard method for Noack Volatility by TGA. There are also two CEC methods.

The method in our TGA is D6375. We do not modify the method

I look at it like when described by Rolls-Royce as producing "sufficient" power. The Noack is undoubtedly very low.
