Oil Analysis on Pennzoil Ultra
Here we go. Pennzoil Ultra is a relatively new product. Supposed to be their top of the line oil. So far, six Ultra Used Oil Analyses have been reported on BITOG.
I've made a chart of the UOA results, which is attached below. To me, the wear metals either look great or vastly improved. The TBN looks strong. Viscosity may be on the thin side, but that's good for MPG.
If you get a UOA on Ultra from your G37, please post it here. Thanks!

Here's the first VQ37 Ultra UOA, thanks to l2awin:

The updated Ultra chart is attached. Note that we have engine Universal Averages on 5 of the 7 UOAs to compare against. So far, Ultra is below the Universal Averages in all wear metals except Aluminum, but that result is skewed by a 2010 Genesis which reported 15 Al. Here's the kicker. That Genesis averaged 39 Al in 2 prior non-Ultra UOAs, so 15 Al on Ultra was a real improvement.

Do the low viscosity numbers indicate shearing here?
For reference the Nissan Ester Oil Viscosity numbers hovered around 8.1@100C and 53@210F. Although those were from slightly shorter intervals as well.
I know this is only one report, but can somebody smart translate this?

Generally speaking, the thinner oil you run, the better your gas mileage. At normal to short OCIs, you usually want to run the thinnest oil you can that protects your engine.
If you want to run extended drain intervals in an engine that can run hot like ours, you might want to start with a thicker oil. In this regard, the Ultra Euro 5W-30 is much more viscous to start than regular Ultra 5W-30, and is more appropriate for long OCIs (which is what the European car makers specify).
Ultra Euro is hard to come by right now, but it will soon be readily available.

I've just recently switched from Mobil1 to Penzoil Ultra and the first thing I noticed (I only have ~150 miles on the Ultra) is my MPG went down ~3-4 MPG.
I used to be able to get 24 on the highway without even trying. I could drive it hard on the highway and still pull 24. Now I have to really try to even get 21. If I drive it hard at all it drops to 20. Not a huge deal b/c 20 is still good but compared to the 24 I was getting it feels low

It seems more likely the change in oil had something to do with it than just a random bad tank of gas doesnt it?

well there is absolutely no difference in the car other than that...I drive the exact same routes the exact same way. The only thing that changed was the oil.

I think I might wait to see what its like over a longer period time. With such a short data sample of only 150 miles, there can be NUMEROUS reasons for the fuel mileage decrease. Watch it over a few tanks of gas and see what it does.
3-4 mpg is pretty extreme for oil. Especially going from one synthetic to another and staying at the same 5w-30 weight. Id guess over a 1,000 mile period, you wouldnt see a difference.

I guess its all relative. And I agree what you are probably going to post in response, that your Eneos looks better. But compare it to the Ester Oil Nissan recommends...... as I posted in the other thread on this UOA:
Its shearing a little, but no where near what the Ester did. The virgin SUS @212 viscosity of the Nissan Ester oil I think was around 60 and mine sheared down to 53 after 4k miles, and I saw numerous others in that range.
The VOA I saw on the Ultra started at 57.5 and sheared down to 54.8 and the Platinum was 57.4 to start and the OP's sheared down to 55.2, both after 5k miles.
I'd still put in either Pennzoil product over the Nissan Ester for longer OCIs.
I agree with the Blackistone copy and paste though.
You guys could both be on "schedule 2" and change it at 7500 miles with the Pennzoil.When I hit 20,000 miles I hope my UOA's look that clean!
While Im not bowing down in awe and declaring this the new nectar of the Gods, I would use this over the Nissan Ester oil in my car..... especially for longer OCI's.
Im still waiting to see UCLA Bruin's new Eneos UOA along with VOA and waiting for another Ultra UOA to pop up. I would prefer to see a few different data sets before making any conclusions. You might get one guy who drives his car hard vs a guy who puts 7k all highway miles on it so seeing numerous data points kinda eliminates the driver to driver variable.

Back to Ultra, if an oil starts as a thin 30-weight and ends as a thick 20-weight, what exactly is the problem IF IT PROTECTS THE ENGINE AND HAS PLENTY OF TBN FOR THE OCI?
In fact, wouldn't your MPG be better with such an oil compared to one that remained thicker?
