Went to autozone the other day found the GC,checked for the "made in Germany" on the back and bought 4 quarts, not sure how much this oil usually costs but I paid $5.19 a QT. Was telling my neighbor some of the things I read about GC from here and how it's supposed to be green, I opened one QT and sure enough it's green. Now to see if it's better than the Mobil 1 I normally use, I've read alot of people say how when they switched to GC their engines ran quieter so I'll see if that applies to mine as well.
