True but the HTHS is going to be over 3.5 regardless with the 0w40. He knows what he's looking for and I would suspect, based on experience, he has a good idea of how this oil would perform on the performance tests under A40. He's a tribologist after all.
Unveiling the Superiority of Pennzoil Ultra Platinum Oil: A Detailed Analysis by Mr. Lake Speed Jr.
So can we say PUP is a group V Ester based oil?
I used to think Pennzoil Ultra Platinum was the best of the best, but without PAO, Ester, and since it's on the thinner side of the 5W-30 grade (almost a 5W-20 by Kinetic Visosity @ 100C), I lost interest in it.
I also have doubt's on the anemic additiive package that Pennzoil oils have shown in virgin oil analysis here on BITOG.
Theoretically the GTL process yields an oil which flows better in the extreme cold and also resists oxidation better in extreme engine heat,
but it's unknown if these hot/cold temp advantages are only a negligable and tiny unmeasurable difference when compared with a regular group III full synthetic.
An interesting comparison would be Pennzoil's Ultra Platinum GTL based oil versus a low priced regular group III full synthetic like SuperTech. There might not be any noticable differences in extreme cold flow or extreme heat oxidation resistance between the 2.
Without any testing, my thinking is that all domestically produced group III and group III+ (GTL) oils are about the same in extreme cold / extreme heat flow/protection, and only differences will be seen if you compare with a Group IV (PAO) / Group V (AN + Ester) formulation.

No. We just know it's there per the FTIR results shown in the video. Esters, and AN's as well, typically account for a small percentage of total volume anyways.
$55/jug makes ESP look even better.
Especially when Autozone sells Mobil 1 ESP 5w30 for like $35 to $37…. And shockingly that is not a sale price. It’s the price every day.

Why wouldn't I go with Pennzoil ultra platinum here as Project Farm found it third best compared to amsoil and red line, which is expensive!
None of his “tests” for motor oil are relevant to what actually happens in an engine. The Pennzoil isn’t bad by any means however, especially if you stick with manufacturer recommended OCI’s.
Oxidation of 10? I kinda thought no one paid any mind to it if >30? Id have to see where Redline, Amsoil fall in their numbers before I got head over heels for PUP.
I think the oxidation of 10 is due to just the borate esters from the boron, where as Amsoil and HPL/Redline/Mobil etc. are blending in group V base oils. The boron additive is what is driving the oxidation in PP.
Red Line has the highest oxidation numbers I've seen, followed by Amsoil. Red Line is 90-120 and Amsoil is around the mid 50's to 60's range. Mobil uses AN's which don't show the same spike.

I would think any 5w30 would have faired well in a 4000 mile trip
I'm focused on that phlebectasis on his lower lip and my strong desire to take a freaking laser beam to it...
Here's my prediction for his Porsche. Whatever he's using right now is good enough and when he uses the PUP it will be indistinguishable...you know like most decent quality and up oils.

I proved to you guys years ago based on UOAs that PUP was better than the critics said it was, so it’s quite bittersweet to see some of you fawn all over today like there’s some magical revelation thanks to LSJ 
I went 17k+ on PUP about 4 years ago and some folks said I was crazy and that PUP wasn’t fit to be a long drain oil…

Been using Pennzoil Ultra Platinum for many years, but, my newer Toyota cars need 0W16. Tempted to use 0W20.
That's what I do. Didn't see a change in MPG, but, it's mostly highway driven. I would think if it were short-tripped, there might be a slight chance a 0w16 would have some MPG effect...but, it might be too little to notice amongst the noise of variables.
P.F. also has a video posted around a year ago . 4 5w-30 PENNZOIL oils are compared . They are the Syn-Blend , Full synthetic , Platinum and the P.U.P.. Includes V.O.A. for each oil from BLACKSTONE Laboratories . V.O.A.s' start @ 7:14 minutes in the video .

So what oil do you currently use then?
What in your UOAs proved this?I proved to you guys years ago based on UOAs that PUP was better than the critics said it was, so it’s quite bittersweet to see some of you fawn all over today like there’s some magical revelation thanks to LSJ
