No problem and yes I did. Amsoil z rod 10w40, amsoil XL 10w40, and amsoil ss 0w40
I have another voa of amsoil premium protection 10w40 posted as well.
Definitely not with the calcium levels. Kinda surprised they didn’t offset it with magnesium to be sp rated friendly. I’m sure they have their reasons for it.
Someone's gonna take that bait and bring up hpl 0w-40... Might just be me actually
But Amsoil is great stuff, just not very lspi safe with that detergent pack in applicable engines. Many off the shelf 0/5w-40 are toned down now.
Who makes that hpl 0w-40?Someone's gonna take that bait and bring up hpl 0w-40... Might just be me actually

Ester free by the looks of the oxidation.
They might have a good reason for the high calcium formulation, but they're recommending it for applications that might require an LSPI-friendly oil, like MB 229.5, and they really shouldn't be.

I said the same thing on the Facebook group where he also posted this VOA
That's a good thing, right? Oxidation is supposed to be as low as possible. I remember about vegetable oil during a coocking class I toulk ages ago. If oxidation is bad for cooking oil, I can't imagine it being good for engine oil.
Where is the oxidation seen?
It's a 40 grade therefore the API limits don't apply.
There are Euro's that are SP compatible & I was just distinguishing this didn't seem to be the case on this particular oil. Some folks may want SP Euro while others don't. Should be some SP Euro 40 grade oils on the market that add packs would look a bit different. I'm using 5w-40 Mobil FS that "Meets" SP for example. We have options.
Esters are made by reacting acid with alcohol. Alcohols have oxygen in them and the oxygen is also in esters. It’s incorrect to think of alcohol and the ester that gets created as being oxidized, in the same way as an ester that gets oxidized naturally later in its life. The oxidation test detects the oxygen in the ester. The change in the oxidation result from VOA to UOA is what matters, since that truly does indicate how much unwanted oxidation has occurred.
Under Fluid Properties, at the far right of the report. Just to the right of the Base Number.
+1. I know M1 FS states "meets the performance requirements" of SP. Iirc the allowance for higher phosphorus levels is 40 grade as the reason for this.There are Euro's that are SP compatible & I was just distinguishing this didn't seem to be the case on this particular oil.

The FS in 30 grade I think says same thing. ESP might actually be SP.
Overall, not you btw, people don't really understand that LSPI occurred because of engine tuning and the reduction in phosphorus levels (emissions). Iirc the ACEA Cx oils can easily meet SP but the ACEA Ax can only meet the performance requirements of SP.

It's interesting that some of the newer European oils are doing away with esters, at least per virgin analysis. Any reason for this? I've seen it mentioned in patents of using "cleaning booster", whatever that is..... Mobil 1 ESP 5w30, as well as all Mobil 1 Triple grades including FS 0w40 now have a virgin oxidation of <10.
If you look at some of the highest priced oils on the market they usually have a group V common denominator (POE/AN/Diester).
I wonder if esters are being replaced with newer additives.
Young adds: "Some elements of the chemical composition of our new engine oil are a departure from what we would normally formulate a product with.
"What was a long shot a few years ago - a vision of a low ash, high temperature, low friction engine oil that incorporates bio-based components became a reality this year, thanks to the efforts of our whole team, in collaboration with Honda and Red Bull.

I’m curious about that as well. Wondering why. Even the off the shelf euro oils have dropped significantly in oxidation value. As we know Valvoline restore and protect has a very low oxidation value however cleans the engine very well and doesn’t show up at all on the tests. I’m curious if theirs new base oils that don’t show and provide better results. I don’t see a reason why amsoil would step back always going above and beyond for their oils.
Also curious if they are gonna wait for sq to come out to make any changes to their full sap formula to be more lspi friendly in direct injection engine unless there something about this oil that I don’t know about to be a lspi quencher even with the calcium level.
That sounds right.
It does look like the add pack is preventing the 5w-30 FS from being API SP & they are only saying "ETR". However, the 5w-30 ESP seems to claim SP. That would make sense since it has lower Ph in the ESP. What I find a bit odd is the additive for the 0w-30 ESP is 800 Ph & 900 Zn. You'd think that would get the SP & not ETR. It should have a similar add pack to the 5w-30 ESP.
5w-30 FS = SP ETR - ACEA A3/B4
5w-40 FS = SP - ACEA A3/B4
0w-40 FS = SP - ACEA A3/B4
0w-30 ESP = SP ETR - ACEA C3
0w-40 ESP X4 = SP - ACEA C3
5w-30 ESP = SP - ACEA C3
