To the people running extended oil change intervals, I'd highly recommend using a synthetic/fleece filter.

A lot of the more expensive "high end" filters are made by the same companies using the same materials as less expensive filters. For example, here's what they have to say about the K&N filters:
this is why i'm excited my work is finally starting to carry the mobil filters.

Thanks for the link
