Taken from my cousin's 2005 Mustang GT. About 6 months (4,000 miles) on OCI using Pennzoil Platinum 5W-20. Looked good, even with the large gap around the seam there were no tears. End cap came unglued, which I find to be typical for Purolators. Not the best photos I've ever taken, but hopefully they will suffice. They seem to be good filters for sub 5k OCIs. I wouldn't trust them not to tear if pushed over 5k.
