Changing the filter in between oil changes is an interesting thought. On my F150, I use the oil meter, so routinely go to around 7500 miles in between changes. I'm actually changing that one in a couple of hours here - meter is at 12% and 7100 miles. That filter sits right on top too.
I used to be an, "every 5000 miles like clockwork" guy, and in the really old days, "every 3000 miles like clockwork".
