Is PP a heavier weight 30 as well like GC? Only have 10 qts of GC left and need a good replacement for my Nissan VQ35DE which prefers heavier 30s. Thanks!

Oil used for analysis has been in since May 07, used for 5,000 HEAVY city miles. Portion sent in for testing was drained from oil filter, as only the filter was changed. Oil = M06 GC 0W-30, filter = OEM 9E000 Planning to do another test when I reach ~7,500 miles total on the oil.
