If you pour German Castrol into an empty Mobil 1 bottle you will have Mobil 1's highest quality 30 weight.

I have not bothered to compare the pour points myself, but that said, there is a statement on the Mobil site to the effect that the "old" Mobil 1 0w30 is the same product that's now sold under the green cap. Here is the "blocked and copied" text from the Mobil web site:

They are the same formulations as the products marketed prior to 2008. As the importance of fuel economy has increased, we felt it was important to communicate to consumers which products in the Mobil 1 family offer the greatest potential for improved fuel economy. Mobil 1 Advanced Fuel Economy oils are engineered to deliver outstanding engine protection while improving fuel economy.

ekpolk,
Here is the old formula's MSDS with a -54C pour point:

It was ACEA A1,A5,B1,B5 back then. AFE is just A1, B1. I know this is the 2001 formula but this formula made it through at least one other incarnation I just can't find the MSDS. It carried the Corvette spec too.
