At what intervals will these previous Amsoil filters still not become "too restrictive" ?
In closing, even if the Amsoil filter has become too restrictive, will it start releasing "previously trapped dirt etc." into the engine OR will it just affect fuel economy (after the filter has become too restrictive) ?
Why? The media filled up as stated.
When? I think 15K-25K miles. But even then, it was quite rare.
I think it would have gone into bypass at some point.
