Really helpful. Thanks!
Very impressive oils.
Looking forward to seeing results from people running it and some UOAs.
The 25k mile test with a turbo GDI Ecoboost monster is most impressive to me.

Me to literally yesterday i checked it and it was still the old one lolGreat, I've been refreshing this page for months and you get the drop on the one day I forgot!
The important notables to me (starting TBN isn't a concern in use, but it is notable to be fair)
Better Noack in the 0w-20 and 5w-30 grades.
The entire lineup appears to have better CCS scores and Flash/Fire points.
Of course, this doesn't tell us that much, but some improvements are nice there and is in line with their claims to have much better results in testing; which is the most important thing,
It was a really good oil before. Nothing to indicate it won't be as good and seems to be better.
Anyone racing to see the SDS yet?

Yes I’m looking forward to someone decoding the tea leaves. What are the base oils?The important notables to me (starting TBN isn't a concern in use, but it is notable to be fair)

Agree. It’s a big hole in the line up.
On paper, I guess. But in practice? Does anyone actually need 5w-40 vs 0w-40 Signature Series in order to decide to buy their 40 grade, solely on the starting "w" rating?

Well, the 0W-40 is an ILSAC oil (or has been historically), so a very narrow range of applicability.
I suppose if Amsoil were a company that was based in Europe, maybe they'd actually have the 5w-40.
Also, I've got no experience using anything above 5w-30 in my personal vehicles.
Ok I checked for 5W-30. Nothing in there about base oils that I could see.
I noticed it wasn't shown for that grade. But it and the following are dated as revised in February 2026. Not sure if this reflects the formulation change being it's 5 months old.
The 0w-20, 0w-30, and 0w-40 shows a range of 10%-<30% here

Good question but I don’t know why they’d list it for some and not all if they didn’t have to.
At least, not per the SDS. But, again it's likely the old one and regardless it's not exactly a recipe books anyway.
No clue whether it's concrete based on an assumption if it would be "required to be" listed; if it's past a certain amount or the laws around disclosure.
But, then again it doesn't show much of anything in the 5w-30 SDS; which is kinda the point.
The SDS sheet is for what it is for hazardous materials involved!!!!, not a recipe for other than that. If a certain base oil formulation is not deemed dangerous then it is NOT on the sds list., the actual formulation is generally proprietary information. to the manufacture of the product. so only you are assuming what happens here.
Thanks for pointing out the obvious.

I received these in the mail today. It’s for my wife’s 2021 Kia Telluride. The vehicle has 49k miles, all those miles was Kia oil from the dealership. Instead of the dealership doing the oil changes, I decided to do them myself. I want to not void the warranty so I decided to pick a great oil that matches all the requirements based on the owner manual. Based on this thread and the pictures previously posted these appear to be the new formula, is that correct?
I believe that the gallon jug is the new formula since it says that it is API SQ. The quart bottle appears to be the old formula since it SP.
