You're are of course right in principal.
No of course I'm not, I stated it tongue in cheek.
Oil pressure is NOT a representation of hydrodynamic lubrication. You keep mistaking the resistance to flow of oil through a bearing for bearing hydrodynamic separation.
If oil pressure was representative of hydrodynamic lubrication, there would be no requirement for different viscosities with BMEP output, petrol or diesel...and obviously Subaru don'y think oil pressure is the answer either.

And no one said it was oil pressure but rather oil back-pressure as indcated by a OP gauge that just happens to correlate to HTHSV.
