I'm very curious about the origins of Amsoil's newly revised EAO oil filters. The newly released EAO17 suggest that it's built by Champion Labs, however, there is no listing on Champion's site suggesting this. Take a look at the pictures I took comparing both filters.
The print on the top of both cans are identical, other than the top "serial/batch/tracking number".
The cans themselves both look and feel identical.
The bypass plate is identical, with the exception that Amsoil's version is zinc plated for extended shelf life rust prevention. You should also note that the anti-drain back valve is the same, with the exception of color. Material could possibly be different, but unless I cut both open, there is no way to know.
Amsoil's bypass valve and center metal can is identical to the Royal Purple 20-500 as well.
Amsoil EAO17
Royal Purple 20-500
Royal Purple also has micro glass (i.e. nano-fiber) media inside with wire backing, just like Amsoil. *This is not a 20-500 filter - different base plate*
I'm convinced that Amsoil's EAO17 is built by Champion, however....more evidence is required to confirm it.
Anyone have a clue?
