This filter was used on a 1997 Saturn SL1 SOHC for 3,500 miles and nine months. The car has 151,000 miles on it and is averaging 1qt every 1,000 miles. The car has been neglected in the past and even run with the oil level so low that the oil pressure light flickered up hills...
The filter has ~131.5 square inches of media (~848 square centimeters).
Notice how much debris is caught between the pleats on the right side of the picture.

I'm not a huge fan of the way that the spacer that holds the ADBV mounts to the filter cartridge. I'd prefer it if there was some sort of gasket between the two parts instead of having metal on metal contact. Either way, I doubt it makes much of a difference.

The wire mesh behind the media is coated.
This is what I was able to scrape out of a few of the pleats. The debris is mostly made up of solid pieces of carbon.
This is what the top of the engine looked like when I replaced the valve cover gasket yesterday.
