Ah yes, it is wonderful to see a new member of the Royal Elvish Order of the Green aka the REOG; there will be festivities in the Black Forest tonight (well actually this morning, Elvish time)
Doesn't work that way....The "GC" is an anomoly and not a regular item......and to further rain on the parade....it has been changed to a yet undefined/untested formula.....so...I will use up my stash of 04GC and continue on with "known" tried and true brands....
GC is only available in qts. at Autozone and "could" be closed out in your area. I see difficulties finding it in LA, so buy up a bunch now while available if you want to run it.
GC is available via mail-order, but the price is punishing.
