About 3X a day a new thread is started on GC, German Castrol. This thread will suffice from now on. Use it to post pictures of the GC bottle, where to buy it, why to buy it, why not to buy it, why to talk about it, why not to talk about it, and any other why's you can come up with. Talk about the smell, the color, the lot numbers, the price, leaky bottles, the elves, how it works in your auto, why it stinks, why it is the greatest thing in the store. Why your engine knocks with it, why it made your tire go flat, why the engine idles slower, why the stuff costs so much etc. Have at it. Now all new members can go to one thread and it will contain all the info they can digest. So post away in here.
