Yea, some white paper from a very reputable source that you can find, if YOU want to. It's been posted on this site before ( I think I did just for YOU at one point) to make it easier for you.
I always make it a point to source my claims with links or images. You could learn from that approach instead of being snarky.
That said, I located the thread, I think your memory is off:
I saw a LSPI whitepaper somewhere and they showed where a high Ester oil had the largest and quit drastic id I remember right LSPI reduction factor (vs each) over Moly, CA and Mag. You guys may know I am going off looking at it 3 years ago. I am running a low CA (1650) compared to some oils...

I posted this table from STLE in the thread, you'll note the slight
increase of LSPI events with the addition of esters:
This is because, per the following quotes:
STLE said:
The ability of a base oil to act as a solvent (i.e. solvency) may be a contributing factor in increasing the frequency of LSPI events during operation of a direct fuel-injected engine. Base oil solvency may be measured as the ability of un-additized base oil to act as a solvent for polar constituents. In general, base oil solvency decreases as the base oil group moves from Group Ito Group IV (PAO). That is, solvency of base oil may be ranked as follows for oil of a given kinematic viscosity: Group I>Group II>Group II>Group IV. Base oil solvency also decreases as the viscosity increases within a base oil group; base oil of low viscosity tends to have better solvency than similar base oil of higher viscosity. Base oil solvency may be measured by aniline point (ASTM D611).
STLE said:
Ester base fluids, which are characterized as Group V oils, have high levels of solvency as a result of their polar nature. Addition of low levels (typically less than 10 wt %) of ester to a lubricating composition may significantly increase the resulting solvency of the base oil mixture. Esters may be broadly grouped into two categories: synthetic and natural. An ester base fluid would have a kinematic viscosity at 100° C. suitable for use in an engine oil lubricant, such as between 2 cSt and 30 cSt, or from 3 cSt to 20 cSt, or even from 4 cSt to 12 cSt.
Note you never provided a source in that thread for your statement, I'm the one who posted the above material. You also never responded to that material. So, you were saying?
Back to your post though:
Who's hyping it, who is discounting it?
Clearly, you are hyping. I don't think anybody is discounting, simply injecting some reality into the marketing-heavy spin being pushed by yourself.
I know they are not all Ester based as you would not have seals left if it was. All I said I use it since I run a small red glowing turbo so I want some Ester to take the heat. I don't trust PAO in a extra high heat scenario as I learned first hand from work. EVEN Summits PAO that has even more Ester then the normal OEM Altlas Copco oil PAO oil, I would varnish up. I even went up against their engineers because they thought I was nuts saying their PAO oil was not up to THEIR OWN use case. I had all my documentation from Polaris Labs tests $ 800 worth of testing brought forward and after that they did not say a word. I just got a wink from the the states service manager saying he was on the emails and he said "good job" with a wink. Virgin oxidation levels are close with my Redline and my Summit group 5 compressor oil, so correlate it as you may. I just brought up he has a choice of Redline since looking up Schaefers I found a price of $12.99 and you came back with your nerve was hit.
Yet you chose to focus on the "Group V!" in your statement, and calling out your own take on its abilities, rather than indicating that the oil was primarily Group IV based with some Group V content.
There are various grades, and viscosities, of PAO, just saying PAO is being just as vague as proudly proclaiming "Group V!" with liberal interpretation being left up the individual reading it. Given that the majority of the Redline base oil blend is PAO, how do you propose that the POE is doing the heavy lifting on "taking the heat"? It's much more likely that, given that their products tend to be heavier for the grade, that they are using a heavier PAO base.
You didn't hit a nerve, I'm just not a fan of somebody sounding like an infomercial promoting a product, and making claims without sourcing them, which is common courtesy.
Just saying Scheafer's is full of BS marketing, as I was a dumbars for believing their tech dept, as the choice to use their oil almost took out my compressor at work. I opened up to do UOA and gel chunks were all floating on top. A group 3 oil where the compressor kills OEM PAO oil into starting to varnish at 600 hour on their 8,000 hour oil. Will a smoking high lower particulate count, and failed every varnish test. Switch to Summit Ultima Group 5 oil (12,000 hour speced oil) zero varnish, but I still dump at 8,000-9,000 as I like to keep clean air compressors. He does have options I guess I like having a 6 NOACK oil, low CA and very low Ash and a Group 5 to take my turbo's red hot heat. Maybe if we call that oil Yellowmark Oil you won't have a nerve hit.

Not sure what any of that rant has to do with the OP's vehicle, which isn't a compressor? Your inclination to bloviate when triggered is impressive however!
I'm not defending Shaeffer, I don't use their products, but I also don't see what relevance their product's lack of performance in a compressor has with this thread.
If you've got more to add, preferably on-topic, I'll gladly hear it.
