Being convinced I need Versatrak for my AWD system, I purchased some from Amazon. The description shows the label, and proper part # in a 16.9 oz bottle. The stuff I got had a slightly different label. Beneath the word Versatrak, it has the numbers 75W-85 GL-5. Also it's 1.06 pints. I was afraid it was some kind of knockoff so I returned it, and ordered some from a GM direct parts dealer. I got the same thing. Is this the right stuff?
