I can't access the document you linked to. But as far as I know, this is the same oil as Pennzoil Ultra Euro 5w-40 which we have over here. You should be able to google its specs. What sort of data are you looking for exactly?

Sorry if doesn't work - could you re-try to open it, please? I'm interested in TBN, viscosity index, sulfated ash. Probably, should be great to see a VOA.

OK, I can see it now. Thanks! The specs appear to be identical to Pennzoil Ultra 5w-40. See here: http://www.pennzoil.com/documents/PENNZOILULTRAEuropean5W40.pdf According to the VOA I did, TBN was 10.4, although I it may have been an older version of the product... http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=2100590#Post2100590 We can always use another VOA if you're volunteering. smile

Actually, viscosity at 100C of the new M1 0w-40 has gone down from 14.3 to 13.5. It is now a light 40 weight. smile
And before that [14.3] was 14.0 cSt. Years ago I think it was 15 with an HTHS of 3.6? Now we're at 13.5 with 3.8.
