GC is available at AutoZone. Its actual name is Castrol Syntec 0W-30 European Formula. Be sure to look on the back of the bottle for the Made in Germany stamp. This is why BITOG'ers call it German Castrol.

Amsoil and Redline will definitely not be cheaper than M1 0w40! I pay $10/qt for RL 5w30. RL 0w30 is $1/qt more. I can get M1 0w40 at my local Meijer store for $6.80/qt.
dave at red line said 12000 miles the most i ran this oil is 7500 miles 1.5 years..no oil sample taken..iam easy on all my vehicles though i have confidence in red line/motul mix.

Pep Boys still has it in their roller-racks as well, but their sales are not as frequent (nor as good) as AZ's.
Oops, I forgot about the name change. It's Edge with Syntec Power Technology. 0w30 in the black bottle. The API rating will be SL. ACEA A3/B3/B4. BMW Longlife-01.
Here's a link to the data sheet:

I've had little luck getting them to look it up unless I had a bottle for them to scan. Once they have the code, they can see which AZs in town have the stuff, and how many.
Don't count on getting the correct info on the phone.
I found these Castrol Edge with Syntec 0W30 ... it says made in germany in the back. Are these as good as the old green formula? I heard the old formula was the best for my ls1!
I just looked at O'Reilly's website and noticed that you can order the European Castrol 0W-30(GC) and they will ship it to your nearest store for you to pick up.

This was debated extensively here when the green GC was phased out.
The eventual consensus was that there was no real difference between the two, although you'll see a post every now and then where someone finds some NOS green GC.
Most AZs around here have GC.
The only PB I ever visit has it on clearance at $6.19/qt, while the nearest O'Reilly's said that they could order it.
Still, if you think you need such a high HTHSV oil, why not use M1 0W-40, which has a higher VI as well as a more modern formulation?
