I hear you guys. I posted knowing full well I'd get called out but I promise you I push it until I can't take feeling the added vibration from the engine, either in miles used or in the level. Yes, I am that tuned into the changes.

Tcoat, one thing I just remembered is that on my last car I took to changing the filter every few thousand miles and just topping off the oil. I haven't been doing that because this engine is still under warranty and I've been keeping records. Some of the head loss is due to reduced flow through the filter.
Just do what feels right as long as it's within the interval specified in the owner's manual.
