Just check the manual. The c8 requires dexos 2 (or 2023 its dexos R) 0w40 oil. Theres three oils available that meet this (2 are identical oils actually).
1. M1 ESP 0w40
2. M1 Supercar 0w40
3. M1 ESP x3 0w40
The one referenced is indeed an approved oil and arguably a the best of the three

Mobil has discontinued the ESP for 23. The options are the ESP X3 (dexos 2) and the Supercar (dexos R). The 23+ Stingray’s are spec’ed dexos R and from recent dialog with Mobil they claim that the SuperCar is the only product for this application. I did notice that the X3 does have a slightly higher viscosity though. The SuperCar is currently hard to find and seems to be a bit more expensive.

You can buy supercar from Walmart (online only). But yeah I have a 2022 so i go with esp x3 that has much better high temp protection.
Put in your car information then search the term "oil"

No and both oils are very close in chemistry based of the data released by Mobil. Definitely not “much better”, but maybe a little better.
I have had some dialog with Mobil via email. I will inquire more about the two options. Mobil has not re-added the C8’s to the application guide since the change. What is most important is the noack volatility and phosphorous content.

I have also had email exchanges with Mobil and was told that dexosR supercedes dexos 2. And someone posted a reference, direct from Mobil (and not second hand from a third party website) that said ESP Formula 0W-40 (not to be confused with ESP X3 which was the subject of my question) and Supercar are identical, at least at the time the material was published.

I was answering your question in regards to the difference based on the information that has been released from the manufacturer, not a third party, about the difference between the 0-40 esp x3 and the 0-40 supercar. Not the previous esp.
The pds does have some important information about the physical properties, such as the viscosity, shear and flash point. These properties are relative to the chemistry. There is not much known other than what has been released by Mobil.
This is speculation based on the known viscosity and the limits of allowable phosphorus for catalytic emission vehicles one can deduce that these are very similar. As mentioned if we knew the noack and phosphorus values maybe we could quantify the difference between the two current offerings. IMO these are very close in performance. The esp x3 is specified to have been developed for applications using particulate filters.

Yes, thanks. And your answer to the question - do any of the parameters reflect increased temperature protection - was no. There are several parameters that appear to have something to do with high temperature - Kinematic Viscosity at 100C, Hi-Temp Hi-Shear Viscosity at 150 C, and Flash Point. I was asking the person that made the statement if any of these reflect the protection at higher temperature. I was not trying to make a point - I'm just interested in how it was determined.

I had heard about it on bobistheoilguy site which I've been part of for years. Some of those guys are immersed in tje tech side of oil, it's overwhelming. They had put out a lot of Info on that oil at that time and I remember it just being a robust oil that met the Porsche test standards which are very stringent. I read over data sheets and comparisons, check out that site for additional info but know it's in elite territory to meet a Porsche test and wear standard.

3.8 is significantly higher than the 3.53 which just barely skates by the minimum required 3.5.
as far as virgin oil analysis, these were done at different labs so take them with a grain of salt. I use three labs and their values are regularly off by around 10 to 15 percent. Nothing jumps out from them ...

Thanks! That's what I was wondering. I can see the difference, which was a little over 7.6% higher, but don't have a feel for whether or not the difference is significant.

Those oil analysis’s are very close. Viscosity is a very straight forward measurement. Based on the tests the old esp was very close to the x3. There are manufacturing tolerances, it is possible that they could overlap when in the min and max condition. Based on the information so far, the difference is small and the overall benefit might not be measurable. I’m not trying to be a naysayer, but just practical or realistic. There is always a possibility that there are economic reasons behind the different versions. Would not be surprised if GM profits from the dexos labeling or Supercar product.

I wouldn't call it a massive difference but definitely significant. To put it into perspective generally oils from 0w20 up to 15w50 have from around 2.5 to 5.5 high temp high shear viscosities
