I would think syn media could last far longer than that.
However, I've seen cellulose filters last far longer than 5 years and be OK. I'm not advocating for that, just telling you what I've seen. Specifically oil and fuel filters.
I realize what the OP asked, but
I can't even comprehend leaving an oil filter on for longer than 12 months max, let alone 3-5 years, no matter what the filtration media was constructed from...
Depends on how many miles are put on the oil filters. Lots of guys (including myself) have vehicles that might only get 1000~1500 miles a year put on them. So they use a good full synthetic filter with a silicone ADBV and change the oil every year, but leave the filter on for 2 or 3 years. C&Ps of those filters show zero difference than if they were changed every year.
Gotcha Zee...I understand. Guess I still put too many miles on yet!!!
