Sorry, no pics, but...
They were both filters from auto-rx clean cycles. One from a 2002 3.5 altima (Purolator) and the other was a 99 LHS (STP). Each filter had about 1200 miles. Both cars have about 58K
The Purolator: Cut it open, media was pretty much evenly spaced, the endcaps were not a secure as I would have liked, and the antidrainback valve was still flexible. This filter had gritty grime, but it was minimal.
The STP: Media was very evenly spaced and very secure the endcaps, but there wasn't as much media. Also, the center tube support was like a plastic crate and not metal with holes. ADBV was still soft. The debris in this filter was smaller than grains of sand, and had near mud like deposits b/w the pleats.
