i know this is old news, but this filter has been serving duty on my truck since about 2011. I drained it once 2 years ago without changing the filter, and ran a 2 year OCI on the next change. so a total of 3 years in service. the truck is a 83 chevy k20. it is my powered wheelbarrow and spray rig in the summer, and a plow rig in the winter. gets tons of idle time, but not much road time. I can verify with my records, but the total miles driven on the road since 2011 is about 700 miles. with all the horror stories about the supertech and ecore, i thought i'd have a let's see. i have to say i was genuinely surprised and most surprising: made in USA! odd. i really expected to see some type of deterioration being in service for 3 years. the end caps are still firmly glued and the filter core is wholly intact. it is now wearing a napa gold. i do not intend to keep them in service this long again ... but i did find this interesting.
