all this filter talk is just silly, have you noticed how most makers have at least two grades of the same filter now?? the upgrade or "gold" series if you will is the old good filter and the regular one is the new cheapo one, just get the gold series filter of whatever maker you like, i usually buy NAPA gold if only because i do most of my parts shopping there.
just like all those big "what oil" debates,,, other than a few exceptions they are all relatively the same, proper maint is most important to good lifespan.
