I was on the Pennzoil website and saw that PP is being marketed as meeting the new GM requirement, SN requirement, and GF-5 however PU does not. PU does exceed some of the GF-5 criteria for "engine cleansing and protection requirements" however it is still only a SM/GF-4 and in the Q&A session a question was asked that started with "You state that Pennzoil Ultra™ already meets the new SN standards..." and Pennzoil did not refute nor confirm this, they simply said that Pennzoil works to meet any new requirement.
So does PU meet the new GM, GF-5, and SN requirements?
