The X4 PDS was updated recently to add A40. Somewhat odd because this contradicts the product positioning and advice of everyone else previously regarding A3/B4 (A40 base sec) and C3 (C40 base spec) interoperability. It makes sense from a practical perspective, since I am guessing one could make a C40 oil that would pass A40 tests, discounting the spec minimums.

It's the base oil that carries the strength of this Mobil-1 ESP.
Definitely should be on someone's purchase radar, who's looking for a SP in 12.5 viscosity range.
Nice find Buster.

What’s the HTHS of this stuff?
I think it is 3.5!
So which one has better specs?
5/30 esp or the standard Euro A3/B4 0/40 /5/40
I think MB 229.5 is about as good as it gets for wear prevention.
Source for these numbers?
there are differences concerning pour point,flash point between these 2 sheets.
not that matters much but which one is the right one?

Noack - 8.6%
Some comments from the site:
"1) Since the oil has to pass more demanding fuel economy tests, here in any case, molybdenum was replaced by an organic friction modifier (OFM), which is not visible in the analysis.
2) Fortunately, we now know what Infineum uses in MB 229.71, most likely they used it by analogy with Infineum C9440 glycerol mono-oleate organic ester friction modifier (guess).
3) There are no esters, yes - but esters are bad for the quick release of alkaline properties, which this mobile has always done - this was its main disadvantage. They were one of the last to abandon esters...
4) There is clearly a bit of PAO, most likely even mPAO, and no thickener, as there is very little PAO in MSDS, up to 5% to 3%, and it won't improve the performance much. Meanwhile, NOACK has 8.6%, and a suspiciously high CCS = 6350, and no less suspicious for adding PAO, the pour point is -42C. Vanguy that there is no longer a polymer thickener here, you need to send this sample to Shear Stability and check it. Now the analysis costs 5000 rubles, you can chip in and check.
5) it contains a lot of succinimides, dispersants, amine and phenolic antioxidants."

appart from the excellent noack ,what is the conclusion? is it better than the sn api or worst?
:
Noack is actually no longer "excellent", just average now with this SP flavor.

No idea. Because the metallic additives are so low, moly gone and oxidation value around 10, people naturally assume it's worse. I don't believe that.

Noack was 7.1% in the previous version. This is average for a good 5W30.
Anyone know the Noack for esp 0w30?
ROC VOA showed 9.1% 3 years ago.
i know previous was lower,seen it here,talked many times.but i meant for a sp flavor ,isnt it excellent? which other SP 5-30s have lower knoack?
