I just changed oil on my truck at 11K miles. Cut open the filter. This is the 1st time I've used a cheap walmart filter, i bought the Motorcraft FL-1a, under 4 bucks.
I still had my used m1-301 laying around from the last oil change. I cut both open. I counted the pleats on the Motorcraft, it was 42. I counted on the M1, well I started to, got half way around and it was 40 when I stopped counting. Not sure it matters, both looked in good shape, no blockage, sludge, but since I go high miles between changes I guess I'll go back to the higher end filters.
