European vs non in the 0w-40 flavour:

AZF:
KV100: 14.8cSt
KV40: 84.6cSt
VI: 184
CCS @ -35C: 6,062cP
Flash: 222C
Pour: -50C
NOACK: 7.7%
HTHS: 3.76cP

EFO:
KV100: 13.3cSt
KV40: 74.7cSt
VI: 182
CCS @ -35C: 5,888cP
Flash: 232C
Pour: -51C
NOACK: 9.9%
HTHS: 3.7cP


It would seem the EFO might have slightly more PAO in it?

Other than the NOACK, I'd say EFO wins.

Like the looks of AZF. If I didn't have a warranty on my vw I would run it. I think it would do well.

Looks to me like it will crank and flow marginally better under all conditions. For PCMO, Im not a huge fan of overly viscous 40wt oils personally... Id rather it be as "thin" as possible but in the range. I dont own firebreathing performance cars that are tracked, just twin turbo engines that like a 40wt oil... and the 3.7 HTHS is so close to the 3.76 value of the other oil that its effectively the same, and a good enough value for me.

I just want the lower NOACK due to having a DI engine.
