What oil pressure should I be looking for then at revs with:
Std oil pump? 50 psi
or
High pressure oil pump? 70 psi
Dropping to under 30 psi at idle when hot.
Hi
Yes, it would be too thick when hot. Here is some information about why we don't recommend 10w-60 very often.

I don't know what pressure it should be reading, but people often worry too much about oil pressure rather than flow rates, it's the flow that gives the protection. Also, it can be that thinner oils flow better, helping to generate a higher pressure.
