Ok. I can not find 0W30 GC in the Houston area -- been to 3 Auto Zones and all they have is the US stuff. But my warranty calls for 5W40 VW approved oil anyway so I am running the BC 5W40. Not to worry though! I was changing my oil yesterday and I used a red funnel. I noticed that the way the light was hitting the gold stream of oil and the red funnel turned the BC into a light greenish hue by some law of physics that I know nothing about! So I guess if you are like me and can't find the green stuff, use a red funnel when the sun is out and pour it just so. No if by chance someone knows where in Houston I can get the real deal though, I would like to start hording the 0w30.
