I just wish Shell would jump on that; I suspect they could cure a lot of PUP problems very quickly that. way.

They still should, but we still have to be cautious about sump size and such things. However, all things being equal, I would gather that an A3/B4 type lubricant would be able to go longer on an OCI than a basic A5/B5 lubricant.
I'm not convinced about the M1 issue and A5/B5 any more than I am with QSUD and A5/B5. The M1 labeling and the data sheet and the website don't quite match, so I'm really not sure which side of the fence the A5/B5 matter has fallen on. Of course, no one really looks at A5/B5 in North America except us, anyhow. Mobil does have precedent for having screwy labels on their jugs. I've mentioned elsewhere where they wrote one of the wrong ACEA specifications on Delvac 1 ESP 5w-40, a spec that is long, long obsolete, and that error has even stuck around with the label redesign. Mobil is usually quite careful about such things, but there is precedent for a screwup.
QSUD's 5w-30 ACEA stuff seems to have fallen off their data sheets, too, and I'm not sure what to think there, either. Did these companies just not wish to bother anymore, since almost no one cares? Did it coincide with when the ACEA 2012 specifications were supposed to be replaced by the 2014 ones, but were delayed? Do the products indeed not meet them any longer?
So, that's why I disagree with Gokhan, but don't disagree with Gokhan.
His point is valid, if we're darned careful, and your comments make that clear. M1 and M1 EP are still marketed and guaranteed as long drain oils, regardless of the ACEA sequences. Same would go for Amsoil and RP. Eneos is probably quite capable, despite not having A1/B1 A5/B5, at least in its North American guise. But, there are some rather weak things out there marketed as synthetic.
On the other hand, one could probably find rather equal performance between M1, QSUD, and PP, despite the vagueness of ACEA matters lately on the first two, and the clarity on the latter one. I just wish the oil companies didn't have a history of laziness when it came to bottle labeling and data sheets, and we wouldn't be spitting into the wind like we are here.
As for Mobil 1 HM stuff, I wonder about the timing of the stuff in relation to the delay of replacing ACEA 2012, and the other little possibilities I've already put forward. So, Mobil 1 has no Chrysler spec because Mobil is annoyed with Chrysler. They put a ridiculously out of date ACEA specification on Delvac 1 ESP 5w-40 labels of two different designs (but not on the sheet or website). And, the ACEA specifications on M1 PCMOs have been mysteriously reshuffled.
They blew through their ink budget on the dexos1 markings. That has to be it. PP and PU won't waste ink on mileage warranties, QSUD yanked the ACEA stuff, and M1 cut the ACEA specs, all to save ink. I've got it!
