Pennzoil Platinum lineup sure isn't anti-shear capable, when reading many UOAs. Now Gokhan states the SP GF6 Platinum has increased VIIs noticeably more, to meet MPG mandates.
All this fight against lspi, turbos, direct inject, timing chain wears, engine cleaning....etc...etc... is going to show a negative-side with engine wear.
I look for the oil producers to constantly tweak this SP / GF6 formulas for the next few years. I'm not sure the brand spanking new formulas arriving this year, will look the same in a couple more years.
