I believe the Fram rep mentioned in a thread here not to run them past 15K as is indicated on the box.
I know many guys do and few if any seem to have any problems.
It seemed the media integrity was more of the question than dirt holding.
Amsoil claims their EAO filters can go for up to 25K.
I haven't seen a longer claim from a spin on, but am curious what you guys have found.
