Went to GC this oil change, and bought five quarters earlier in the week. However, after I went with a higher capacity filter, I ended up a bit short. Went back to Auto Zone to get a top-off quart, went to the rack, sorted through the yellow label Syntex 0W-30 until I got a red label, and bought it. Wasnt until I got home that I saw the made in Germany was missing, and the list of specs that it met was decidedly shorter. I compared the empties, and yes, they were all the German version and so stated on the back of the bottle, right above the UPC code. When I took it back, I compared the yellow labled version with the new, red labeled, "USA" version and they appeared to be identical. Looks suspiciously like a red labeled version of the yellow label product. Did I miss something, or is this a CASTROL shell game to fool even the BITOG regulars by just changing label colors on the US stuff? (P.S. Got to tell you, first time in my life I went back to exchange a quart of oil, but the AZ guys did it, and, I got to tell them about the BITOG site in the process, and that yes, there is a difference in Syntex products of the same viscosity).
