Here is a photo of the filter from my 88 F-150, 5.0 liter, taken between the treatment and rinse phases (supposedly there should be even more crud after the rinse). A-RX was applied at 142K into whatever dino I had lying around , and run for 3K. Vehicle has been in my possession for the last 60K and had 3-4K dino OCIs'.
As bad as the crud looks in the photo, it doesn't do justice to the actual. Many of the folds were like the ones on the left in the picture.
