I could be mistaken, but I thought the M1 0w-40 was on the list.
Nonetheless, if you were to go for an out of spec choice, I'm not sure I'd go with the regular 5w30 M1. I'd still be looking for something with a little higher HTHS, and I'm not sure what else is missing from "vanilla" M1 5w30 versus a speced lube. Delvac 1 ESP 5w-40 has SA around 1, as does the Delvac 1 ESP 0w-40, and at least the former is very affordable up here. We do have some HDEOs in 0w30 up here, without excessive TBN, but I doubt you can get them down there.
In any case, if it were me, I'd prefer to stick with a specified lube, or not stray too far from it. We definitely need someone in this thread who has a bit more familiarity with the ACEA diesel sequences and what might be a suitable alternative outside the official list, and I know who that is, but we put him on the spot way too often as it is.
One may simply have to sit down and compare some spec sheets the hard way. Petro-Canada also has a rather long list of various HDEOs from 0w30 on up, with fairly comprehensive spec sheets (including ACEA approvals, ACEA meet or exceed, and so forth).
