Never said amsoil made that claim. Pablo stands behind that belief apparently
Amsoil severe service Engine opened with 82000 miles, 10k oil changes...CLEAN!!!

I don’t think people understood the nature of my comment or the sarcastic ridiculous rhetorical exchange
I don’t. Some people might I don’t know.
A note about Amsoil's up and coming new formulation. The fact is all oil makers will discreetly change the formulation from time to time for various reasons. When we do these oil samples the formulation we see from the lab seems a little different than whats on the oil makers data sheet. It could be certain chemicals/materials are not in a great supply or that the oil maker is monitoring the used oil analysis themselves and decided to change the formula to make them better...etc. It could be possible that the new Amsoil formulation is already on the shelves and they are just not telling us...
Did it burn any oil? Seems like there's lot of reports of those K series engines burning oil later in life, but they seem to respond well to a Valvoline Restore and Protect cleanup.
Just a note...Amsoil uses mainly Group 4 PAO basestocks with Group 5 Ester base stocks as their soluble additive carriers in their Signature Series oils. In their XL and OE lines of PCMO's they are Group III hydro cracked oils.
When thinking of Amsoil Signature Series its like what Pennzoil Ultra Platinum is to the Pennzoil brand. The Signature Series competes against the other oil makers top brands. XL is designed to compete against the lesser brands such as Pennzoil Platinum. High Mileage is to compete against something like Valvoline MaxLife.
Im in the camp of if we going to buy the better oil than lets buy their best which does not cost a lot more and in this case its Signature Series with high quality base stock and high quality ingredients. In the XL, OE and HM world its the lesser Group III with high quality ingredients.

Yep. I can show what $2 per qt maxlife 0w20 synthetic, used exclusively on our 2018 rogue from new to 85k did. I changed it every 5k religiously and when I snaked a scope down the valve cover it was pristine. Not a discolored spot to be had. Maybe supertech could have done the same, but I know valvoline did for sure.

The latest SDS for their Signature Series motor oils states the PAO content is 5-10%, from which I gather the balance of the base oil blend is likely Group III (certainly not ester, PAG, or AN). Only a GC scan can tell for sure. At such a low PAO level, esters are not technically needed although may be present.
SDS for SS Series Oils
It did, but not badly. At its worst it was burning about a quart per change (10k miles). It would have been a good candidate for Valvoline Restore and Protect, but sadly its gone now. Niece traded it for a new civic.
But its a good example of conditions being ideal as well. That car saw regular commuting of 150+ miles per day. I also drove to project sites all over the East Coast and as far west as Indiana. I five years I put nearly 200k miles on that car. So it spent its majority of life in the sweet spot for the engine. Long freeway cruising.
Pretty sure you can't backwards engineer an oil with an SDS.
A few years ago the European SDS showed GTL/PAO. My guess is it's a III/IV/V blend. Could even be some mPAO. With Noack very low across the SS line, Dan Peterson saying they definitely use esters, and oxidation value in the SS line ranging from 48-62, I think it's a III/IV/V blend.
Of course not, but there are some valid conclusions that can be drawn if one has formulation expertise.
You can tell, to a limited extent, what Amsoil lines they save for the top tier base oils. Look at the price, oxidation value and Noack. OE/XL - dry - similar to off shelf synthetics, priced accordingly. SS/Dominator/some Euro oils (Euro line varies in price significantly from $11-$17/qt) show virgin oxidation >40. Even with that said, you can't conclude what exactly and how much of each are being used. Then you also have additive levels, type/quantity of VM, type of AO etc....
Amsoil has provided more than any other company data that shows their SS is very very good.
RL/HPL go all out across entire range other than RL's OE range. Smaller market share. Amsoil has had to cater/cave to expand.

I kinda wonder if Amsoil's OE line would even exist; the label itself not necessarily the formulation that goes into it, if folks weren't convinced SS could somehow void their warranty.
I mean, there is likely a considerable number of DIY'ers that believe if it doesn't say "API service level x, y, z," then you "can't use Amsoil during warranty!" so really they had no choice but to accommodate this portion of the market for more sales; likely including some of their own customer base due to ignorance! (I say that with love)Which, in the end, IMO all of that is fine and good, so long as their top-tier boutique quality product continues to be just that!
If I were Amsoil, I'd likely have caved, too. OE line for those that need it to say API for warranty. Their better tier products remaining for after warranty and of coures the majority that believe in Signature Series outright.

I wasn't commenting on the quality of the AMSOIL Signature Series line, just correcting the statement from another poster that they are mainly based on PAO.
AMSOIL Signature Series is a great choice but if you're looking for max shear stability have you considered Red Line? To this day the most shear stable oil I've seen based on many used oil analysis. I don't think it's due to the VM type either, but rather lack of VM. They use less VM. Their 0w40 is ok but I'd opt for Red Line 5w40.
Oxidation value is 129. This is likely the one grade Dave G. referenced when he said some Red Line grades use up to 40% POE. Noack is 5.6% too.
Very consistent numbers between ROC and Spanish guy's VOA. Identical oxidation value and Noack.

I can pour in a $5 can of Gunk Engine Flush and run for 5 minutes, and see the same resulting pictures.
Overbased cleaners i.e. Amsoil, Mobil, etc, eat ALL seals and gaskets.

Wrong
Did you just wake up today, choose violence, search for Amsoil, and troll every thread?
