OK, your call...
As I keep saying...the BOQI does nothing that you say it does,
* doesn't represent hydrolytic stability,
* doesn't even give the same "quality index" for three 100% PAO basestocks in the same family, nor 6 oils blended with them,
* does not represent the context of the patents that you claim support them.
re the Harman Index, it is the ratio if the HTHS to the theoretical 150C viscosity were the oil a Newtonian oil and not have temporary polymeric shear non Newtonian effects. It has a sound theoretical basis...and claims nothing more than demonstrating the non-Newtonian behaviour of an oil.
You are confusing the two issues.
If I divide the viscosity by the vapour pressure and divide by NOACK, I have a meaningless number, regardless of how "correctly" and accurately I calculate it.
