Are you actually saying that HPL Euro (and HPL No VII) should not be used, with 2024 technology in play ?https://www.savantlab.com/documents/52/Q1_2014_TEOST_Technical_Brief.pdf
this is a deposit formation test that high moly oils are exempt from in certain viscosities as they fail it. the deposit formation tests are more stringent in euro manufacturer specs.
more here:
We've had quite a few good posts about the TEOST 33C test and whether it's relevant. Star polymer VII, very high levels of moly, concentration of VI, AO and base oils all play a role.

Lots of moly.
Also lots of calcium.
I am gonna guess that 2024 HPL Euro (and No VII) is nothing like the oil that was tested in 2014.
