4200 miles on the Motorcraft 5w-20 oil and 2500 miles on this filter.
This truck had the FL-820s with the big hole in the media. I replaced that filter with another FL-820s before I found the hole. When I found torn pleats on the FL-400s I took off my Focus, I replaced the second FL-820s, which had loose bits of adhesive (pic included), with this Napa 1372. I changed it early partly because of the loose glue and partly because now my oil changes will be every 5000 miles on the odometer.
I don't know if the debris is the glue from the last oil filter, or if the air filter has a weak seal. It feels snug, but the slide in tray makes it hard to tell. There are no leaks in the intake or intake hose. I have never seen it before on this truck.
The FL-820s with loose glue.
The FL-820s with the hole for those who haven't seen it yet.
