I dare you to find a better wear metal UOA at 5000 miles on a G37 than this UOA on Pennzoil Platinum.

Raising a thread from the dead . . .
I would like to see what the SUS Viscosity index is on Pennzoil Ultra that has done 5,000 miles in a hard driven G37. I have had five UOAs at 5,000 miles each using Mobil 1 EP on my G and in every one the SUS Viscosity was below what it should be.

I'm preparing to make the switch to synthetic for our G, and after reading probably hundreds of pages on UOAs at both BITOG and the370z.com, I've decided to use PU. (there is an epic multi-page oil thread somewhere on the370z.com that is a great read for our engine)
But I agree that pretty much any quality synthetic will give acceptable results. I may also one day mix PU with Edge titanium for our G. I mix synthetics in our MB, and get great results.

When I was choosing a synth to use on my G the only real "requirement" I was looking for was some ester in the additive pack (to technically fulfill Nissans requirement [for previous model years] of ester oil)
Valvoline full synth, Pennzoil Platinum and Ultra, etc. all have something in it to fulfill the requirement (per the manufacturer). It sounds like Napa full synth oil is relablled Valvoline full synth so thats another option.
I stuck with PU because of the UOAs posted all over the net.
