About 5000 miles on this filter. Didn't see any problems. Well made filter. Filter was on a 1999 Ford Taurus 3.0 Vulcan with 210,000 miles. Oil was Mobil Super 5000 5w20. I changed to PYB with Fram Ultra. Enjoy! Made in USA! The material felt stiff, but no rips or tears. A little wavy. Pleats were well spaced. Valve was flexible, but a little stiff.
