I am sure I am the only one to make this mistake, but I thought I should share:
For 20 years I have assumed that oil entered the center of the oil filter and flowed to the outside. This is because of the perforated cage in the middle. I figured large debris would get stopped there before entering the paper element. As such, when I cut open my filter I only inspect the inside surface.
Today I decided to look at the other side, and what do you know, for the first time in 20 years of inspecting filters I found some carbon deposits. Not sure how I could be so dumb, but I am!!!
