Apparently, Extended Life does equal Global.
The Peak website doesn't show the Extended Life, only Long Life, Global, and original, so it is obviously new.
I noticed at a Walmart a week or two ago that as two assoc. were stocking the antifreeze shelves the new Extended Life was being mixed in together with the existig Global on the shelf at the same price, and I would swear the same UPC. The front labels of the two were identical and both used the same color bottle. The back labels were a little bit different but it was obvious the Extended Life was replacing the Global. And now the Global is gone from all the shelves around here.
I'm obviously concluding that the Global is no more. The Peak website is just lagging behind a bit.
