Anyone know what the viscosities of virgin G...err...Castrol SLX 0w30 is at 40C and 100C.

what they are saying is the both forumalations meet the minimum testing standards, that says nothing about one oil being better than the other as nothing is said about any of the oils meeting higher standards. So you are left to think about which forumlation ultimately performs best, in terms of minimum standards they both meet them and in Castrol's definition they are the same. As oil nuts we know some oils can perform better than other irregardless of them meeting the same standards.

I should search before I ask, but my presidential campaign is eating up all my time. . . Has anyone done VOAs or UOAs on the <b><i>yellow label</b></i> stuff so we can tell for sure? I don't doubt that IF the yellow label DID comply with the higher A3 standard, and thus presumably perform "better," it would be marked A3. But I'd really like to see a scientific indication of just how much difference there really is in such things as viscosity stability, TBN retention, HT/HS vis, etc.
The viscosity of the yellow label oil was not sufficient to meet the HT/HS min requirement for ACEA A3
Forget the YELLOW label stuff for a minute....
Does anyone know if the RED label "Made in USA" stuff is green as well? I've never looked...actually, I think all the Red label stuff here is "Made in Germany".
If not, reply by asking them why the "Made in Germany" version is green??? Same formula?
By the way, thanks Losiho.
