It is not a good reason, but what fix did Amsoil make when all the filters were clogging and they pulled some off the market for a remake?
I think they put out a service bulletin (seen it talked about here a few times - search for TSB: FL-2009-05-01) that changed the recommended filter application or changed the filter usage interval, and they might have redesigned the filter media to be less restrictive.
