Synpower and PU don't use esters in their oils. I find that interesting. A former BITOG member once said that additives are becoming the base oils. I don't know how much of this is true, but from what I read, it's become a trend. From what I understand, esters have always been one of the most costly components. (Why many like Redline). bruce/mola/Tom maybe can chime in here.
In the Pennzoil FAQ page, they mentioned how Grp III's have better solvency.
I'm sure it goes back to the same general concept, which is that oils can be built very well using a variety of components, therefore only the end result is what matters.
In other words, don't equate base oil #'s with performance. It's the total product as mentioned all the time.
