I've always been skeptical about comments such as "my car likes Brand X oil" or my car runs better on "Brand Y oil" but I have to admit to a noticeable difference now that I've switched to GC. I started running it in my BMW 740 and through the coldest days this winter (I'm in Canada) I noticed easier starts compared to the 5W-30 I was running previously. My car also hasn't burned a drop of oil and I've gone 9,000 km since my last oil change. Hard to say if the engine is any smoother, because the BMW V8 is pretty smooth to begin with.
I also switched my '99 Ford Explorer from dino 5W-30 to GC and the difference is even more noticeable than in my BMW. My Explorer has always had a pronounced rattle from the overhead cam chains, and the engine is definitely quieter with the GC in it. My Explorer also has high mileage and has been used to tow my boat, and so far with the GC I haven't burned any oil yet.
Fortunately, at least for now, in Canada we don't seem to have the supply issues you have in the US. I can get GC anytime at Wal-Mart, NAPA, Canadian Tire, and Parts Source. All major retailers.
