It'll be interesting to see what PP knocks loose, if it's never had synthetic oil in it before. The GTX is going to be tough to beat for the price (once the free PP is gone).

With the calcium and magnesium levels the GTX shows in this UOA, I don't think that there's much for PP to knock loose.
Too short a run without doubt but this GTX UOA from a Nissan V-6 is a hall of famer.

20W-50 is good stuff. A loooong time ago the OP and I had a Z car thick v thin discussion (re:argument).

No arguing with these results.

I'll add some personal notes to the uoa. It's my only car,my daily driver. Multiple daily short trips,long extended high speed 80-90mph highway runs. I've had it a little over 15 years. I bought it with 30,000 miles on it,I'm the second owner. My first oil used was Syntec Blend 10W30 (and a Fram Orange Can of Delight) the day I bought it and brought it home. Then a whole collage of oils (haha I get bored easy). Mostly Mobil 1 10W30 or 15W50. I used Royal Purple 20W50 for awhile. Mobil 1 10W40 High Mileage for a pretty long time. GTX 20W50,Edge 5W50,then Edge 10W40. When Walmart discontinued Edge 10W40,I went back to GTX 20W50. My current fill is Pennzoil Platinum 10W30 High Mileage.

The GTX 20W50 looks to have a great add pack (moly and zddp).
