Most of us have seen or are at least aware of "ancient" 0W-30, aka AC or American Castrol...
...and, of course, are familiar with GC or German Castrol.
However, I recently saw what I assume to be something even older, and am wondering if any of you have any experience with or knowledge of it.
It is a lone bottle at a K-Mart, so who knows how or why it ended up there.
The graphics are similar to, but not the same as those on an AC bottle. Where the AC bottle has "Syntec" in white, this one has "Synthetic" (or maybe "Syntec") in silver. Above and to the right of that it has "New" on an upward slant in a box.
There is no copyright date on the back, though it does say "Made in America", is SJ/ILSAC GF-2 and has the same SKU # as found on GC Green bottles.
There isn't the familiar date stamped on the bottom, though there is a date on the bottom of the rear, and it is M82716A54A4 1316.
Do you believe that "8" refers to 1998?
Does any of this ring a bell with any of you?
Unfortunately, no photo.
