Personally, I don't have any problems with Penzoil. People debate the particulars and the minutiae of oil on a constant basis...and for me, the bottom line is this: they all work well when used properly. I've run Penzoil before and never noticed any problems from it.
I can't say much about the 2.5, but the 4.0 was designed in an era when our cheapest, most crap-tastic oils would have been considered state of the art. It's a very tolerant beast...as are most engines. Thus, I believe that dino oil, a good filter (I've even used Fram and never killed an engine...my stars!), and changing both regularly will serve you well.
If it's worth doing, then it's worth overdoing.
