Or 16,372Km. This filter was in service from October 27th, 2013 to September 1st, 2014. Oil used was Pennzoil Ultra 5w-30 SN. Vehicle is a 2002 Ford Expedition with the 5.4L 2V and 280,5xxKm on it at the time of this post (roughly 175,000 miles). Filter was cut with a reciprocating saw. Sorry for the cutting surface, I couldn't find any cardboard today Not a hint of tearing, media was wonderfully pliable still, though a bit wavy, likely due to it being used all last winter including that beautiful -30C start I posted when we were driving through NB/QC. I tried tearing the media with my fingers by pushing on it where it met the glue at the can and was not able to do so. Also, the potting/glue at the ends flexed readily with the media, FWIW. Another FL-820S has gone on in this filters place.
