Apologies - when I said "What I have noticed is that the 0/30 is showing higher cold pressure, but lower hot pressure than what was in there before, but I don't know what that was.........."

I meant the 5/30 is showing....blah blah blah.

It had been a long day! innocent

I know modern engines are very tolerant of posh thin oil, but as a practiced amateur mechanic, 5/20 seems on the thin side, and I suspect very hot tickover pressure will be affected (lowered). Just my opinion.
