Can you explain what those compounds are and why it would be significant Mobil may have changed formulation?

They may not be considered hazardous and thus, not need to be mentioned.

It group 5 oil which better in solvancy, seal compabitily. Last longer in engine can extented drain interval and protect engine better cold or hot climate ,do not need viscosity improvers .this base oil is better in every aspect in terms of gtl , group 3 oil which mostly used in syntice oil.

As of today do you have any information which mobil 1 like 0-40,0w20,5w20 etc contain AN or ester. I think I read bitog that either 0w40 msds used to has AN list .

A blend using Esterex and/or AN's still requires VII's if it is trying to meet a wide spread like say 5w-30 or 0w-40. A 0w-20 or 10w-30 can be blended without VII's but they are not common.

No, because Mobil doesn't divulge that information. Their base oil "example" blending chart shows both products however, it's surfing around this board somewhere if you search.

I have search from last 6 month only find that they contain 2% ester oil I even have search in google but no one can able to if any Mobil 1 contains ester oil more than 2 % even bitgo same there no form that have this information even ask mobil 1 but same story it a trade secret. Even if you have any idea about which Mobil 1 contains AN or ester base I will appreciate it.

Most of XoM M1 marketed oil formulations are not synthetic.

The day was many years ago when Mobil 1 was formulated with PAO/AN/POA. I had a jug sitting around as a fond memory of Mobil before BP ruined synthetic oil in North America with their junk group III blends.

Oh, that again … I think they did us a favor … nothing wrong with Group III lubes at the price we pay in the USA … Here is what I bought today for $25/5 quart jug:

4WD, around 60% PAO in Mobil1 Extended Performance 0w20 is impressive, especially at that walmart price point. Mobil1 Annual Protection is similar too, although with presumably better anti-oxidants in the additive package.
Ravenol DXG 5w30 and 0w20, by comparison, has no GroupIII (all PAO+esters base oil), although you have to pay a lot more.

Agree … even though the OLM will have me changing it out by 8k … figured with DI and AFM this will hold up and I don’t bother with UOA … and I admit the 20’s are something I’ve had to get my head around …
now if I could find a good filter with the correct PSI on bypass …

Yeah I posted that same SDS many moons ago. The Only product I could find with significant PAO to be classified as synthetic. No proof though SDS can be wrong/old. Ran it in the wife's Subaru with just MEH result and mucho engine noise. Back to Valvoline 0w20.
An NO, the group III ive run don't come close to performing like a well formulated real syn blend IMO. I do LIke the QSUD but that's a special case for MISSCLASSIFIED true synthetic paraffin. But its a paraffin.

I agree that group 3 oil is no way near true synthetic group 4 or group 5.
