On another note the AMZ/OIL EAO80 oil filter appears to be available to order, $16.60 Dealer Cost.
Maybe you'll have better luck than I do. It shows in stock but when I go to checkout it strips it from the cart stating its not available to ship to my address, or any address I try.
notice how the "S" looks like a "Z"
If I remember the story correctly, Amzoil was being sued by Pennzoil, because of the similarity of the name. The late Al Amatuzio Sr. just flipped the "Z" around and "Amzoil" became "Amsoil". That seemed to satisfy the judge, although Pennzoil was not amused.
Perhaps, John Holmes (very knowledgeable about Amsoil and other topics) can verify for accuracy.
And the “OIL” could also be visualized as “710”......when upside down.Current design, notice how the "S" looks like a "Z"

Just checked my order for 4 EAO80 oil filters and they are shipped. Will be interesting to see if they look the same and are still Made in USA.
