Is GC ONLY available in 0-30 or are there other weights available? Also I read in another post that GC in the USA was only available at autozone, is that right?

It's on the bottle...
And people around here have been saying the 5W40 and 5W50 aren't (completely?) Grp III like the rest of the Syntec line.
I could be wrong though..
