I come from the mazdaspeed world. one of the earliest performance DI engines on the mass market. many more small things to think about on that engine than in the current DI engines, but penzzoil platinum came back with great oil analysis all the time. i used it exclusively on my car from its first oil change to when i sold it at 108 with perfect compression. and that engine was not babied, used, abused and enjoyed with a big turbo and many autocrosses and canyon runs at 350whp and a short stint at 400whp until the clutch could no longer hold. i will continue to use PP in this platform.
as for oil filters, check out this comparison granted it is a few years old http://www.mazdaspeedforums.org/forum/f427/oil-covered-now-what-best-oil-filter-106998/

At one time PennzPlat was the ONLY mass market oil which could beat the Honda HTO-06 turbo spec, and they had an oil on the shelf with an incredible 4.xx volatility rating!
