I cut apart the filter on my 2000 Concorde after about 4500 miles on Schaeffer 7000. I was impressed with some aspects but not others.
The can isn't real thick. Since I poke the bottom of the can to allow it drain fully I can easily compare can thickness with other filters. Mercruiser filters are much thicker.
The red anti drainback valve looks very good. I thought the sealing ring was the same material, but it is black and coated red. There was a surprising amount of red coating it the filter media. They should lose the red coating on the seal since some of it ends up in the filter.
The filter media was attached well to the end caps, but cutting the media away from the caps resulted in some of the adhesive coming off the caps in chunks. It is brittle and does't adhere as tight as it could.
The filter media had a couple of wide pleat gaps.
The relief valve looks good.
As far as what I learned about my engine there was little metal but some carbon. I doubt the carbon is very abrasive, but there was enough of it that I wouldn't consider using the same filter for two OCI's.
Hard to describe how much carbon was there, but I will call it similar to a 1/2-1" long piece of cassete tape (by volume) in each pleat. That is the carbon that is visible, not hidden in the filter media.
